John Cleese says there's one constant throughout his life, from Monty Python through today. He still has a very strong childish side and it has done him well. John talks to Marc about putting that childish side to work when he was doing sketch comedy at Cambridge and why the success of Monty Python had a lot to do with five guys who all liked pushing boundaries. Also, John and Marc try to find the line between affectionate and inappropriate comedy by telling each other a string of off-color jokes.
