"I'm Sorry I Haven't a Clue" developed from the long-running radio sketch show "I'm Sorry, I'll Read That Again", the writers of which were John Cleese, Jo Kendall, David Hatch, Bill Oddie, Tim Brooke-Taylor and especially Graeme Garden who suggested the idea of an unscripted show which, it was decided, would take the form of a parody panel game. A panel game with no competition was not itself a new idea: the BBC had a history of successful quiz shows designed to allow witty celebrities to entertain where winning was not important. Examples include "Ignorance Is Bliss", "Just a Minute", "My Word!" and "My Music" on the radio and "Call My Bluff" on television.
