In 2012, two of Channel 4's most popular quizzes - the topical hit 8 Out Of 10 Cats and the cerebral words-and-numbers game Countdown - came to metaphorical blows as the anarchic comedians of the former took on the brainbox format of the latter.
The gang returned to play Countdown a second time later in 2012.
In January 2013, as part of the next Channel 4 Mash Up, Jimmy Carr, Jon Richardson and Sean Lock hijacked an episode of Deal or No Deal. A number of comedians joined in, plus Rachel Riley and Susie Dent again. Joe Wilkinson acted as the Banker's assistant.
Since 2013, the show has run regularly with multiple-episode series. By their own admission, the stars never thought the format would last beyond one episode, but it still regularly appears in primetime slots (whilst 8 Out Of 10 Cats itself has moved to E4).
