8 Out Of 10 Cats Does Countdown

2012 Specials

As part of a special evening of programming in which a number of Channel 4's most popular programmes crossed into each others' territories, Jimmy Carr hosted an edition of cerebral quiz show Countdown, with Sean Lock and Jon Richardson playing the game. No one realised back then that it'd spawn this long-running show.
