I once turned on The Enemy Within and decided to give it a shot. It's theme is that players have to try and answer trivia questions for money. The player with the most money wins the game. But, there is one player, called the Enemy, who has all the answers given to him/her. If, at the end of the game, the players find out who the Enemy is, the Enemy gets no money. If they do not find out who the Enemy is, the Enemy gets all the money. Overall, this is an interesting show probably worth your time.
