Host Dara O Briain is back with the comedy panel show's traditional helping of seasonal silliness. As well as the usual mix of out-takes, highlights and unseen material, there's a Christmas quiz, a festive Scenes We'd Like to See, a seasonal newsreel from Hugh Dennis and a guest appearance from a somewhat sinister teddy bear. There are contributions from Josh Widdicombe, Holly Walsh, Rob Beckett, Katherine Ryan, Ed Byrne, Romesh Ranganathan and Sara Pascoe, and even something a little bit different in the opening titles too.
