Cleese wrote for the original British That Was the Week That Was (not the less-inspired American copy), and worked with Eric Idle, Terry Jones, and Michael Palin on David Frost's satirical Frost Report.
Cleese was a founding member of Monty Python's Flying Circus in 1969, along with Chapman, Idle, Jones, Palin, and Terry Gilliam.
Cleese stayed with the show for three of its five seasons before feeling that the comedy had declined, and cordially drifting away.
John Cleese was born in Weston-super-Mare, Somerset, England to Reginald Francis Cleese and Muriel Cross.
As a boy, Cleese was educated at Clifton College in Bristol, from which he was expelled for a humorous defacing of school grounds: he used painted footsteps to suggest that the school's statue of Field Marshal Earl Douglas Haig had got down from his plinth and gone to the toilet.
Cleese described it as "a one-man show with several people in it, which pushes the envelope of acceptable behaviour in new and disgusting ways." The show was developed in New York with William Goldman and includes Cleese's daughter Camilla as a writer and actor.
