The show is presented by Angus Deayton. The team captains are comedians David Mitchell and Lee Mack.

For each show, two celebrity guests join each of the team captains. The two teams then compete head-to-head with each player revealing incredible facts and embarrassing personal tales for the consideration of the opposing team. Some of the yarns are true; some are not, and it’s the panellists’ task to separate the facts from the fabrications.

The show airs 21:55 on Saturday nights on BBC One, and was recorded at Fountain Studios in Wembley during March and April 2007.

Working title for the series were Unbelievable and Pants On Fire before the final title was settled upon. Alan Carr was announced as a team captain but was later replaced by Lee Mack.

Initial ratings for the first show in the series indicated 3.7 million viewers - a reasonable share for BBC1 given the time slot.
