Mock the Week is a British topical celebrity panel game hosted by Dara Ó Briain. The game is influenced by improvised topical stand-up comedy, with several rounds requiring players to deliver answers on unexpected subjects on the spur of the moment. It is made by independent production company Angst Productions and made its debut on BBC Two on 5 June 2005. It was created by Dan Patterson and Mark Leveson, the same people responsible for the comedy game show "Whose Line Is It Anyway?"
