Cash Cab is a game show originating in the United Kingdom in which passengers in a specially designated taxi cab are offered the chance to win money by correctly answering a series of trivia questions on the way to their destination. It was devised by Adam Wood. In late 2005, an American version of Cash Cab began airing with comedian Ben Bailey as host. If the passenger stays in the cab, the game begins. The first four questions are worth $25 each, the next four questions are worth $50, and any question thereafter is worth $100. In Cash Cab After Dark, however, all of the money values are doubled to $50, $100 and $200, respectively.
