I remember reading about a guy who was on The Price is Right and got to play the Punch Card game. For those who don't know, you have to win chances to punch out holes on a board, and in each hole is a card with a cash prize amount on it. (I think you could win up to five chances.) Most of the cards said "$100" or some other small amount. There were (I think) two cards with $5,000, and one card with $10,000, which was the highest prize.
You punched all the holes you were entitled to, and then Bob Barker would pull out the cards in the order you'd punched them. You'd have the option to either keep the amount on the card, in which case the game was over, or go on to to the next card - taking the risk that the next card would be for a smaller amount.
Anyway, this guy got a card that said $5,000. The crowd went nuts, and Bob was all "Okay, so you're going to keep that and end the game, obviously." The guy said NO, and then the crowd REALLY went bonkers! Bob was like "You're kidding. You're giving up five grand on the off chance that you MIGHT get the ten thousand bucks? Are you crazy?" But he had to do what the contestant wanted, and .... the next card said $10,000. Cue pandemonium.
I wouldn't have believed it if I hadn't seen the film on YouTube. And the weirdest part is, the guy looked very calm and matter-of-fact, like he KNEW that the $10,000 was waiting for him on the next card.
