The Class sketch is a comedy sketch first broadcast in an episode of David Frost's satirical comedy programme The Frost Report on 7 April 1966. It has been described as a "genuinely timeless sketch, ingeniously satirising the British class system" and in 2005 was voted number 40 in Channel Four's "Britain's 50 Greatest Comedy Sketches". It was written by Marty Feldman and John Law, and features John Cleese, Ronnie Barker, and Ronnie Corbett. Source: Wikipedia (en)
