Larson's episode of
Press Your Luck was recorded on May 19, 1984. With
production code number 0188, the episode was
produced by Bill Mitchell and
executive produced by show co-creator
Bill Carruthers. Larson was seated at the center lectern. To his right was returning-champion Ed Long from California, a
Baptist minister; to his left was
dental assistant Janie Litras. In the first question round, Larson earned three spins. He stopped his first spin on square 17, which revealed a Whammy, but also allowed him to calibrate the timing of his button presses. His next two spins landed on square four, giving Larson the lowest first-half total of , while both Long and Litras managed to avoid the Whammy and respectively accumulated and with their spins.
Second half In the second question round, Larson earned seven initial spins of the Big Board, and his last-place position earned him the first spin. In his first 15 spins, Larson occasionally missed his safe squares of four and eight, but was successful in avoiding Whammies, earning cash and prizes of . Beginning with spin 16, he then landed only on squares four and eight for 29 consecutive spins, totaling in cash and prizes. After this 44th overall spin, Larson was losing his focus. On spin 45, Larson missed the extra-spin squares: "I remember that moment. I was just so drained, [...] I suddenly forgot where the Whammies were. So I stopped and passed control of the board to the other players. I felt so relieved that it was over." Ed Long received Larson's remaining spins and hit a Whammy on his first. When the show's control-booth operators realized what Larson was doing, they called Michael Brockman,
CBS's head of daytime programming. Brockman later told
TV Guide, "Something was very wrong [...] Here was this guy from nowhere, and he was hitting the bonus box every time. It was bedlam, I can tell you."
Press Your Luck producers wanted to stop the show, but without any apparent rule-breaking by Larson, they were forced to allow it to continue. When Litras's turn came around, she passed her last three spins to Larson, who was obligated by the rules to use them. Larson stopped the first two spins in squares four and eight, but he stopped the third too early and it landed on square 17. Instead of the Whammy again, though, it was a trip to
the Bahamas. That ended the game, and after 47 spins of the Big Board, Michael Larson had won cash and prizes (including a
sailboat and
all-inclusive vacations to
Kauai and the Bahamas) totaling . Ed Long still received his from the previous episode, while Janie Litras's last Whammy had left her with nothing.
Fallout CBS's
Standards and Practices department thought that Larson had cheated and was not entitled to his winnings. Network executives pored over the footage, but could find no evidence of malfeasance. Former executive for
CBS Daytime programming
Bob Boden explained in 2007 the network's "prevailing wisdom [...] was that he hadn't cheated; that he was just smarter than CBS." A few weeks later, they mailed Larson a check. He was ineligible to return to the show (as Long had done) because he had exceeded the network's limit of . The episode aired on June 8 and 11, 1984, broken into two parts due to its length. Some at CBS had wanted to cancel the episode entirely, and afterwards made the decision that it never be aired again, even including that requirement with their
broadcast syndication contracts. To prevent anyone from repeating Larson's success, the Big Board was programmed with 27 additional light patterns, and CBS set a limit for contestants' winnings. Larson later contacted
Press Your Luck contestant coordinator and issued an unanswered challenge: "I know you've added patterns to the board, but I bet I can beat you again. How about a tournament of champions?" ==Legacy==
