British game show Golden Balls only ran for three years, from 2007 to 2009, but it created one moment that is totally unforgettable. The basic principle of the game was simple: hollow plastic balls with amounts of money written inside are opened by players, who then vote each other off while trying to keep as much money as possible. At the end of the game, the two remaining players can choose to “split” or “steal” – if they both choose split, they split the money. If one splits and one steals, the stealer gets the money. If both steal, none of them get anything. But what happens when a player insists he’s going to steal? This clip defies everything we know about psychology, and it’s amazing.Get your balls in the game! Donate to the Sean Kimerling Foundation to win the battle against testicular cancer.
