Rob Brydon is back in the host's chair for a festive edition of the comedy panel show with David Mitchell and Lee Mack, as ever, the lightning-quick team captains. Over the course of the show, celebrity guests reveal amazing stories about themselves, some of which are true, and some of which are not. The aim of the game is to fool the opposition into mistaking fact for fiction and fiction for fact. David Mitchell is joined by Miranda Hart and Stephen Mangan, while Barry Cryer and Miles Jupp are on Lee Mack's team.
