Rob Brydon hosts a festive edition of the award-winning comedy panel show with David Mitchell and Lee Mack as 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. This episode's guests are Liz Bonnin, Stephen Merchant, Sharon Osbourne and Dr. Ranj Singh.
