LOS ANGELES (Reuters) - Ten years ago, poker shows proliferated on TV and then faded but with several states and federal legislators moving to legalize the game online, some networks are betting that TV poker is back.

"Online poker will introduce a lot of new people to the game and I think that will bring another big wave to television," said Jamie Horowitz, vice president original programming and production for Walt Disney's ESPN.

ESPN televises the popular World Series of Poker (WSOP) tournament, currently taking place in Las Vegas through July 6. ESPN will air 26 segments on WSOP starting on July 23.

On Wednesday, CBS's Showtime will air for the first time on TV a 2009 documentary called "All In - The Poker Movie," about how poker has come to be part of the mainstream culture.

Hollywood agents, TV executives, poker and gaming executives have been meeting to discuss and pitch new poker programs, from reality shows about female tournament players, to shows potentially featuring new online gaming companies.

Others caution, however, that a resurgence in poker TV needs more than the three states, Delaware, Nevada and New Jersey, that have passed online gambling laws to kickstart the game on TV again.

"Although online gambling may only have momentum in three states right now, it could be a great lead-in for programming," said Alec Driscoll, director of gaming development for American Casino and Entertainment Properties LLC.

Off-shore poker websites such as PokerStars were the forces behind the poker TV boom, starting around 2003, serving as on-air sponsors and buying air time for their own shows.

But that all changed on April 15, 2011, known in the gaming industry as "Black Friday," when the U.S. Department of Justice indicted the founders of these sites on charges of bank fraud, money laundering and illegal gambling offenses.

The sites were closed to U.S. online players, sending shockwaves through the poker world and the TV industry.

Networks slashed shows. But then the DOJ in late 2011 clarified its stance on the Wire Act, enabling states to legalize online gambling.

CASINOS AND NETWORKS EXPECT BIGGER MARKET

Nevada was the first state to go live in late April, while others like New Jersey and Delaware are preparing to start online poker in coming months. Several others are considering similar laws, while lawmakers in Congress are also working on legislation to allow online poker gambling across the United States, giving casinos and TV networks a bigger market.

Larry Gerbrandt, principal of Media Valuation Partners, said the last poker TV boom helped offshore online poker sites to drive viewers to their sites. Gerbrandt said it will take similar investment by fledgling online gaming companies to fuel television, although he believes poker show ratings are rising.

Comcast's NBC Universal's E! Network is developing a new reality show called "Queens are Wild" that follows four top female poker players who room together as they travel the world and compete to win millions.

Ben Spector, of Los Angeles-based Tollin Productions, said he was approached by top Hollywood agency CAA to pitch the reality show on female poker players to networks.

Taiwanese-born professional poker player Maria Ho, who has accrued more than $1 million in tournament earnings, is one of the women featured. Ho is no stranger to TV and has appeared on "The Amazing Race" and "American Idol" and is a commentator on the "Heartland Poker Tour" syndicated TV series.

"When I got into poker, I didn't see myself going down the TV path," Ho said. She gave up plans to go to graduate school to play poker. "It's been the ride of my life."

Gary Quinn, vice president, programming, NBC Sports Group, said the unit is in discussions about different poker projects. It airs the "National Heads Up Poker Championship" and brought back "Poker After Dark" in 2012 after withdrawing it a few years earlier.

New online gaming companies are mulling TV opportunities. Station Casino Inc's Ultimate Gaming, the first company to take online bets in the U.S. in Nevada last April 30, is in discussions with networks.

"We are speaking with NBC and Fox and several other networks to see what the appetite is for the category over the next 24 months," said Joe Versaci, Ultimate Gaming's chief marketing officer.

Versaci and others are watching California closely because of its size and entertainment footprint. "What happens in California in late 2014 and 2105 will be key, not only because it's the epicenter of where TV is produced, but because it's like a country itself and can support a large poker market," he said.

SEOUL (Reuters) - North Korea reopened a Red Cross hotline with South Korea on Friday and invited officials from Seoul to talks over the weekend, a further sign the North wants to improve ties after a barrage of threats to wage war this year.

On Thursday, North Korea proposed talks to normalize commercial projects, including a joint industrial zone it shut down at the height of tension in early April.

North Korea's moves come ahead of a summit between Chinese President Xi Jinping and U.S. President Barack Obama on Friday in California. North Korea's actions, including its latest nuclear test in February and threats to attack South Korea and the United States, are likely to be high on the agenda.

North Korea had stopped responding to calls on the Red Cross hotline in March. Another hotline, used by military officials, remains down.

"We appreciate the fact that the South side promptly and positively responded to the proposal made by us for holding talks between the authorities of both sides," the North's official KCNA news agency quoted a spokesman for the Committee for the Peaceful Reunification of Korea as saying.

The two Koreas have not held talks since February 2011.

South Korea has proposed cabinet level talks on June 12 in Seoul to discuss a range of issues including commercial projects and families separated during the 1950-53 Korean War.

In response, the North invited South Korea to a working-level meeting on Sunday in the border city of Kaesong, where South Korean companies employed 53,000 North Korean workers to make cheap household goods until the North ordered it closed.

Later on Thursday, South Korea used the restored hotline to accepted the proposal for working-level talks but suggested they be held at the Panmunjom truce village straddling the border. It also suggested the talks include preparatory work for the ministerial-level meeting.

Tension escalated on the peninsula after the United Nations imposed new sanctions on North Korea for its February 12 nuclear test, the country's third. North Korea also said two months of joint U.S.-South Korean military drills that ended in late April were a prelude to an invasion.

The international community condemned North Korea for its threats. China, the North's major diplomatic ally, was also critical.

China told a North Korean delegation that visited Beijing late last month that North Korea should stop conducting nuclear tests and focus on economic development, a source with knowledge of the talks told Reuters.

WASHINGTON (Reuters) - Merck & Co's experimental insomnia drug was safe and effective at the lower of two doses studied, a panel of medical experts said on Wednesday, increasing the chance it will be approved by the U.S. Food and Drug Administration.

The advisory panel was convened to help the FDA decide whether to approve the drug, suvorexant, which would be the first in a new class of sedatives designed to help people fall asleep and stay asleep.

On Monday, the FDA's internal reviewers published a report expressing concern about the drug's potential to cause next-day sleepiness and impaired driving. They asked the committee to consider whether patients should be started at a lower dose than that recommended by Merck.

Merck proposed that elderly patients start by taking 15 milligrams of the drug and increase that to 30 if necessary. The company recommended non-elderly adults start on 20 milligrams and increase it to 40 milligrams if needed.

On Wednesday, the FDA reiterated its opinion that there was little evidence in Merck's data to show that the higher dose was more effective than the lower dose, and considerable evidence to show it was less safe.

The FDA's reviewers pointed to an increase in the risk of suicidal thoughts and behaviors, an increased risk of impaired driving, and an increased risk of severe sleep disturbances.

Speaking for the FDA, Dr. Ronald Farkas noted cases in which patients had reported sleep paralysis and terrifying hallucinations. He also expressed the agency's concern about the drug's impact on driving.

"What we are trying to prevent is criminal prosecution of patients taking their drug as prescribed," he said.

Merck celebrated the panel's recommendation, saying in a statement that it was "excited about the potential of suvorexant as a new and different approach to treating insomnia."

The FDA is not bound to follow the advice of its advisory panels but typically does so.

The FDA had asked the panel to consider whether patients should start with a 10 milligram dose, saying data from a smaller trial showed that amount might work for some people. Merck disputed that, saying 10 milligrams would not be effective.

The FDA asked the panel if Merck should conduct an additional trial to further evaluate a 10 milligram dose. The panel voted against that. Some panelists agreed with Merck that 10 milligrams would not be effective. Others agreed in principal with a lower starting dose, but said a new trial would not add meaningfully to the information already in hand.

The panel voted 13-3, with one abstention, that the drug is safe for elderly patients at 15 milligrams a day and for non-elderly adults at 20 milligrams. It voted 8-7, with two abstentions, that the drug is not safe at 30 and 40 milligrams.

The 23-year-old Corbin worked through six innings, striking out five and allowing four runs, to improve his spectacular start to 9-0 for the National League West-leading Diamondbacks (32-24)

His mark ties a team record for consecutive wins to start a season, matching Brandon Webb in 2008.

Arizona broke a 4-4 tie in the sixth inning where they scored three times.

Paul Goldschmidt had a run-scoring single in the inning, his 46th RBI of the year, and finished 2-for-3 with three runs scored.

In Baltimore, Chris Davis belted his Major League-leading 20th home run to spark the Orioles past Detroit 4-2.

Baltimore trailed 2-0 in the seventh before Davis drilled a homer to right field and the home Orioles added two more runs to take the lead.

Davis finished the game 2-for-4 while his nearest American League offensive competitor, Detroit's Miguel Cabrera, went 1-for-4.

Cabrera is batting .367 with 65 RBIs to lead the AL and second-place Davis, hitting .357 with 52 RBIs, but he trails Davis' home run total by three.

In Oakland, the Athletics put an end to pitcher Chris Sale's scoreless innings streak to complete a sweep of the Chicago White Sox with a 2-0 win.

Josh Donaldson's sacrifice-fly in the sixth inning ended Sale's stretch of 28 innings without a run allowed and handed him his first loss since April 18.

Jarrod Parker tossed 6 1/3 scoreless innings for the A's, Jed Lowrie added an RBI single in the eighth and Oakland took three straight from Chicago.

In Pittsburgh, the Pirates rallied from a 4-0 deficit to top the Cincinnati Reds 5-4 in 11 innings.

Travis Snider's RBI single in the 11th completed the comeback win and tied Pittsburgh (35-22) with the Reds (35-22) for second place in the National League Central.

Pedro Alvarez and Garrett Jones each hit homers to help pull the Pirates out of the hole created when Cincinnati scored four times in the first inning. (Writing by Jahmal Corner in Los Angeles; Editing by John O'Brien)

Face transplants are extraordinarily complicated and relatively rare procedures that usually require extensive preparation of the recipient over a period of months or years. But medical officials said the Polish patient's condition was deteriorating so rapidly that a transplant was seen as the only way to save his life. The patient is now being watched for any potential infections.

In a photo taken Tuesday, just six days after the surgery, the patient, identified only by his first name, Grzegorz, was shown giving a thumbs-up sign from his hospital bed. Another picture, based on computer tomography, showed the extensive damage to his skull.

He was injured in an April 23 accident at his job at a stone mason's workshop near the southwestern city of Wroclaw when a machine used to cut stone tore off most of his face and crushed his upper jaw.

He received intensive treatment at a hospital in Wroclaw that saved his life and eyesight. But an attempt to reattach his own face failed, leaving an area close to the brain exposed to infections, doctors said. The damage was too extensive for doctors to temporarily seal the exposed areas.

So he was taken to the Cancer Center and Institute of Oncology in Gliwice, the only place in Poland licensed to perform face transplants. The center has experience in facial reconstruction for patients disfigured by cancer and its experts have practiced face transplants on cadavers.

Doctors at the center said the 27-hour face and bone transplant was performed May 15 soon after a matching donor was found.

The surgery reconstructed the area around the eyes, the nose, jaws and palate and other parts of the man's face. Pictures show stitches running from above the patient's right eye, under the left eye and around the face to the neck.

The donor, a 34-year-old man, was chosen from a national registry of potential donors after his age, gender, blood group and body features were determined to be a good match for the injured man.

The head of the team of surgeons and other specialists, Dr. Adam Maciejewski, said it was the first time a face transplant was carried out so soon after the damage. Face transplants are usually a last resort after conventional reconstructive and plastic surgeries have been tried.

"In such an extensive injury, where the structures close to the skull base and in contact with the brain area are exposed, any infection would be dangerous, not to mention the impossibility to function normally, including problems with breathing, with eating," Maciejewski said. "All that led us in one direction."

"We assume the surgery will allow the patient to return to normal life. He will be able to breathe, to eat, to see."

Maciejewski said that over time, the face will mold to the man's facial bone structure and he will not look like the donor.

The patient is now breathing on his own and responds to questions by nodding his head or squeezing the hands of doctors. But his condition is serious and it will be months before the procedure can be declared a full success, said Dr. Krzysztof Olejnik, head of the team of anesthesiologists.

Another member of the transplant team, surgeon Dr. Maciej Grajek, told The Associated Press that the patient was receiving drugs to ward off any potential viral, bacterial or skin infections, but the face is alive and is healing.

Though he is in sterile isolation, the patient has started the rehabilitation process. He will stay on special drugs for the rest of his life to prevent rejection of his new face.

More than two dozen transplants of the face or parts of the face have been performed around the world. The first one was a partial face transplant in a woman maimed by her dog in France in 2005.

Dr. Bohdan Pomahac, who in 2011 led a team in the United States that performed a full face and double-hand transplant on a woman mauled by a chimpanzee, said in an email he believes that in the future surgeons will decide more swiftly on a transplant, just as the Polish team did.

"This is the way we likely will practice in the future," said Pomahac, a reconstructive surgeon at Harvard-affiliated Brigham and Women's Hospital in Boston. However, he cautioned that patients should be given more time to be fully involved in a decision that will have a life-long impact on them.

"I still think that a traumatized patient, even with all the psychological support, probably has a hard time making the right decision within hours/days after life-changing trauma," Pomahac said.

Dr. Zbigniew Wlodarczyk, who has performed limb transplants in Poland but was not involved in the face transplant, told the AP the surgery was groundbreaking because it was carried out on a fresh injury and on tissues that have not healed, but that leaving such an extensive wound open would have led to infection and the patient's death.

"Such rare but spectacular procedures show the possibilities of medicine today and advance it," he said."This places Poland in the elite group of countries performing such transplants.

In the mix all day during a record 68 lead changes, the popular Brazilian dipped inside defending IndyCar champion Ryan Hunter-Reay on a restart with three laps to go and cruised from there under the yellow caution flag.

He flipped up his visor to wipe tears from his eyes as the crowd roared, and then poured the celebratory winner's milk over his head in Victory Lane.

"I have to say, the last lap was the longest lap of my life," Kanaan said. "I got a little bit of luck today. I was looking at the stands, and it was unbelievable. I'm speechless. This is it, man. I made it.

"It means a lot to because so many people, I could feel that they wanted me to win, and it's such a selfish thing to do because what are they getting from it? I'm the one who gets the trophy. And if you can bring some joy to them and I think the best thing was trying to put an exciting race for them. And I said it before the race, I believed that this win was more for people out there than for me."

Kanaan had his fair share of chances to win at Indianapolis Motor Speedway, but came up short time and time again. He was leading when the rain came in 2007, only to lose to Dario Franchitti when the race resumed.

In all, Kanaan went into Sunday's race with 221 laps led at Indy more than any non-winner except Michael Andretti and Rex Mays but his second-place finish to Buddy Rice in 2004 was the closest he had come to victory. He had a pair of third-place finishes, including last year, again to Franchitti.

"I wanted it all my life, but over the years I was kind of OK with the fact that I may never have the chance to win," Kanaan said. "We can disprove the theory that nice guys don't win. We proved that wrong."

This time, it was Franchitti whose crash brought out the final caution to seal Kanaan's victory.

"It's wonderful for him," said Mario Andretti, himself a victim of bad luck at Indy. "He's raced here long enough that he deserves it, no question."

The win for Kanaan and car owner Jimmy Vasser was celebrated throughout the paddock. Alex Zanardi, who came from Italy to watch the race and gave Kanaan one of his 2012 London Paralympics medals as good luck, wept behind the pit wall as Kanaan took the checkered flag.

"I tell you I'm starting to think (the medal) really works," said Zanardi, who lost his legs in a 2001 crash in Germany. "It's a dream come true to see Tony win, to see Jimmy Vasser win, my dear friend. I'm so happy, I'm so happy."

It was Vasser who brought Zanardi's medal to Kanaan before the race, telling his driver that Zanardi wanted him to rub it for good luck.

"I cuddled with it," Kanaan later admitted.

Fellow Brazilian Helio Castroneves, shooting for a record-tying fourth Indy win, was happy for his long-time friend.

"Finally he's able to win this race. He's so close so many times, but the good news is the good old boys are still able to run fast," Castroneves said.

Carlos Munoz, a 21-year-old rookie making his first IndyCar start, finished second and Hunter-Reay was third.

"T.K. is such a fan favorite, absolutely, it's great to see him win it. If anybody is going to win it in the field, he's one of the few I'd like to see other than myself," Hunter-Reay said. "We were leading on that last restart, I knew I was a sitting duck, and I wasn't too bummed about it because I knew we had enough laps to get it going again and have a pass back. Maybe I would be third on the last lap, which is where I wanted to be."

Only there wasn't a last lap as Franchitti brought out the caution seconds after the race went green.

"I went into the first corner on the last restart and it just didn't turn and then hit. The big, old hit," said Franchitti. "When I saw who was leading, it cheered me up a little bit. He's a very, very deserving winner."

The leaders came to the finish line all bunched up around Kanaan, saluting the longtime IndyCar stalwart who had longed to add the final missing piece to his resume. That was about as slow as anyone had driven all day. The average speed was 187.433 mph, another Indy record.

Marco Andretti finished fourth, failing to win for the eighth time, and Justin Wilson was fifth in the highest-finishing Honda on a day that was dominated by Chevrolet. Castroneves was sixth. Pole-sitter Ed Carpenter led a race-high 37 laps and finished 10th.

For a time, it appeared the win would go to AJ Allmendinger, who led 23 laps in his Indy 500 debut for Roger Penske.

Fired by Penske from his NASCAR ride last year after failing a NASCAR drug test, Penske gave him a second chance with this IndyCar opportunity. Seven years after leaving open-wheel racing, Allmendinger finally ran "The Greatest Spectacle in Racing" and was leading when his seat belt came undone, forcing him to pit.

It put Allmendinger off the pit cycle, and he was forced to stop for gas twice far in advance of the rest of the field. It meant Allmendinger had to drive his way back to the front each time, and he finally sputtered out at seventh.

"Once I figured it out, it was phenomenal. I could drive by guys at will when I wanted to," Allmendinger said. "I felt like we were up front running our own race, and, I don't know, belts come undone. It just popped.

"I'll be honest, pretty special moment to be leading at Indy," he said. "My body kind of went numb, my mind was racing and I could feel my heart beating really fast, and that's a special moment I'll never forget."

A year after 34 lead changes and a frantic finish created what many considered the best Indy ever, IndyCar had its hands full trying to top itself.

This one might have done it, with the slicing and dicing at the front, over and over and over again. There were a record 68 lead changes by 14 drivers, and 28 of the 33 cars were running at the end. With 100 miles to go, 25 drivers were on the lead lap.

"It was a hell of a race. That's all I can say," said Mario Andretti. "This is riveting competition, that's all I can tell you. It's just amazing. The reliability of the cars is there. The product is there. It's unbelievable racing, the best I've seen in years."

Tony Parker had 20 points and nine assists, Kawhi Leonard added 18 and the Spurs wasted little time sending a message to the visiting Grizzlies who are experiencing their first conference finals.

San Antonio, meanwhile, is trying to get back to the NBA finals for the first time since 2007 and looked especially determined in Game One of the best-of-seven series.

Game Two is on Tuesday in San Antonio.

Having been inactive since Wednesday when they finished off the Oklahoma City Thunder in the second round, Memphis came out slow and fell behind by 17 after the first quarter.

The Grizzlies briefly pulled within 62-56 late in the third, but San Antonio spread the floor and hurt Memphis with 14 three-pointers and 28 assists for the game.

Quincy Pondexter led Memphis with 17 points off the bench while Marc Gasol added 15. Zach Randolph had his worst game of the playoffs, managing just two points on 1-for-8 shooting.

Danny Green put up 16 for the Spurs who are seeking revenge for their past post-season matchup with the Grizzlies. Memphis stunned San Antonio in the first round of the 2011 playoffs. (Reporting by Jahmal Corner in Los Angeles, Editing by Gene Cherry)

SAN FRANCISCO (Reuters) - Google staged four discussions expounding on the finer points of its "Glass" wearable computer during this week's developer conference. Missing from the agenda, however, was a session on etiquette when using the recording-capable gadget, which some attendees faithfully wore everywhere - including to the crowded bathrooms.

Google Glass, a cross between a mobile computer and eyeglasses that can both record video and surf the Internet, is now available to a select few but is already among the year's most buzz-worthy new gadgets. The device has geeks all aflutter but is unnerving everyone from lawmakers to casino operators worried about the potential for hitherto unimagined privacy and policy violations.

"I had a friend and we're sitting at dinner and about 30 minutes into it she said, 'You know those things freak me out,'" said Allen Firstenberg, a technology consultant at the Google developers conference. He has been wearing Glass for about a week but offered to take them off for the comfort of his dinner companion.

On another occasion, Firstenberg admitted to walking into a bathroom wearing his Glass without realizing it.

"Most of the day I totally forget it's there," he said.

Many believe wearable computers represent the next big shift in technology, just as smartphones evolved from personal computers. Apple and Samsung are said to be working on other forms of wearable technology.

The test version of Glass looks like a clear pair of eyeglasses with a hefty slab along the right side. Since it began shipping to a couple thousand carefully selected early adopters who paid about $1,500 for the device, it has inspired a bit of ridicule - from a parody on "Saturday Night Live" to a popular blog poking fun at its users.

Other industry experts take a more serious tack, pointing out the potential for misuse because Glass can record video far less conspicuously than a handheld device.

Glass also has won many fans. Google and some early users maintain that privacy fears are overblown. As with traditional video cameras, a tiny light blinks on to let people know when it is recording.

Several Glass wearers at the developers conference said they whip the device off in inappropriate situations, such as in gym locker rooms or work meetings. Michael Evans, a Web developer from Washington, D.C., attending the Google conference, said he removed his Glass when he went to the movies, even though the device would be ill-suited for recording a feature-length film.

"I just figured I don't want to be the first guy kicked out of the movies," he said.

NO GLASS ALLOWED

A stamp-sized electronic screen mounted on the left side of a pair of eyeglass frames, Glass can record video, access email, provide turn-by-turn driving directions and retrieve info from the Web by connecting wirelessly to a user's cell phone.

Google Executive Chairman Eric Schmidt dismissed concerns about the brave new world of wearable computers during a talk at Harvard University's Kennedy School of Government in April.

"Criticisms are inevitably from people who are afraid of change or who have not figured out that there will be an adaptation of society to it," he said.

Schmidt acknowledged that there are certain places where Glass will not be appropriate but that he believed new rules of social etiquette will coalesce over time. Firstenberg said it will take time for all sides to get comfortable with the new technology.

"I don't think we should go into the conversation assuming that Glass is bad," he said.

Indeed, previous technology innovations such as mobile phones and wireless headsets that initially raised concerns are now subject to tacit rules of etiquette, such as not talking loudly on the bus and turning a ringer off in a meeting.

Still, some have decided to leave nothing to chance.

Casino operator Caesar's Entertainment recently announced that Glass is not permitted while gambling or when in showrooms, though guests can wear it in other areas. In March, Seattle's Five Point Cafe made headlines for becoming the first bar to ban Glass. "Respect our customers privacy as we'd expect them to respect yours," says a statement on the caf's website.

The California Highway Patrol says there is no law that explicitly forbids a driver from wearing Glass while driving in the state. But according to Officer Elon Steers, if a driver appears to be distracted as a result of the device, an officer can take enforcement action.

PRIVACY TRACK RECORD

Lawmakers are beginning to consider Glass.

On Thursday, eight members of the U.S. Congress sent a letter to Google Chief Executive Larry Page, asking for details about how Glass handles various privacy issues, including whether it is capable of facial recognition.

According to Google, there are no facial recognition technologies built into the device and it has no plans to do so "unless we have strong privacy protections in place."

During one of this week's conference sessions - an open discussion about Glass - members of the Glass team answered a question about privacy by noting that social implications and etiquette have been a big area of focus during the development of the product, which is still a test version.

Some of the Glass-phobia may stem from Google's own track record on privacy. In 2010, Google revealed that its fleet of Street View cars, which criss-cross the globe taking panoramic photos for the Google Maps product, also had captured personal information such as emails and web pages that were transmitted over unencrypted home wireless networks.

"The fact that it's Google offering the service, as opposed to say Brookstone, raises privacy issues," said Marc Rotenberg, the executive director of the Electronic Privacy Information Center, a non-profit privacy advocacy group, citing Google's history and its scale in Internet advertising.

Rotenberg says his main concern centers on the stream of data collected by the devices - everything from audio and video to a user's location data - going to Google's data centers.

Ryan Calo, a University of Washington law professor who specializes in privacy and technology, said Glass is not very different from other technologies available today, whether it is a smartphone or "spy" pens that secretly record audio. But Glass is on people's faces, so it feels different.

"The face is a really intimate place and to have a piece of technology on it is unsettling," Calo said. "Much as a drone is unsettling because we have some ideas of war."

For all the hand-wringing, some early adopters are sold.

Ryan Warner, who recently graduated from college and who has developed a recipe app for Glass with Evans, said he was surprised by the reaction he got when he went to a bar.

"I was like, I don't know if I should have it on or not.' I was kind of in that phase," he said, "and the bouncer was like, Oh, my god, is that Google Glass?' He was excited."
