On June 2–7, 2010, at the Bellagio in Las Vegas, Laak set the world record for the longest time spent playing poker in a single session. He halted at 115 hours. The previous official record, 72 hours and 2 minutes, was held by Larry Olmsted, set at the Foxwoods Resort Casino in 2004. Guinness allows one 5-minute break every hour, in which Laak could do whatever he wanted, and Laak could "bank" those 5-minute breaks into longer breaks if he played through. Laak banked several breaks to take a 30-minute nap (allowed), but he vows that he did not use caffeine or any stimulants. Playing $10/$20 No Limit Hold'em (with uncapped buyins), Laak finished up $6,766 and donated half of his winnings to charity. He did this for Camp Sunshine, a charity that helps sick children enjoy summer camp. His feat was witnessed live on streaming video by over 130,000 people.
