Walliams & Friend

David Walliams is joined by award-winning comedian Jack Whitehall. The episode includes Jack and David's inappropriate take on Sherlock and Watson, the world's worst dating show contestant and Jack doing something David has never done before - dressing as a woman. There is also the launch of Britain's cruelest reality TV show Celebrity Slammer, in which David finds himself locked up with the Chuckle Brothers.

David Walliams has invited comedian Harry Enfield to be his 'Friend' and the result is a masterclass in sketch. Together they appear as John Torode and a rather fussy Gregg Wallace in MasterChef, portray a hilarious pair of ageing lotharios and take a look back at some of Harry's comedy characters that never saw the light of day, until a certain David Walliams got his hands on them.

David Walliams is joined by stage and TV actress Sheridan Smith, who transforms into a real-life Barbie doll, faces an unlikely dilemma whilst filming a swords-and-sorcery epic and hits all the wrong notes as a cruise ship singer with a chip on her shoulder.
