Wetten, dass..? is a German-language entertainment television show. The core gimmick of the show was the bets: ordinary people offer to perform some unusual (often bizarre) and very difficult task. The other major attraction of the show was the top-ranking celebrity guests. Each of the guests had to bet on the outcome of one of the performances and offer a wager, in recent years usually a humorous or mildly humiliating, originally more charitable, activity to be carried out if they lose. Until 1987, each of the celebrities bet on all the performances and the most accurate one was selected to be that show's Wettkönig ("bet king"). Ever since, one of the people performing the task is selected by a telephone vote.
