To Tell the Truth

To Tell the Truth is an American television panel show in which four celebrity panelists are presented with three contestants (the "team of challengers", each an individual or pair) and must identify which is the "central character" whose unusual occupation or experience has been read aloud by the show's moderator/host. When the panelists question the contestants, the two impostors may lie whereas the "central character" must tell the truth. The setup adds the impostor element to the format of What's My Line? and I've Got a Secret.
