In 1984, ice cream truck driver Michael Larson set a record by winning $110,237 (a combined total of cash and non-cash prizes) in one appearance on the game show Press Your Luck -- and he did it by gaming the system. He had noticed that the Luck board did not rely on luck at all, but was actually running in five predictable patterns -- which he memorized over the course of six weeks, with the help of a VCR. By the time the show's taping was completed, everyone from the host to the contestants were mystified by Larson's amazing ability to avoid the Whammy (the squares on the board which would end the player's turn) and consistently win prizes. For Larson, there were indeed "No Whammies."
