Homicidal Barber is a sketch that appears in "The Ant, an Introduction," the ninth episode of Monty Python's Flying Circus.
Synopsis[]
A customer (Terry Jones) enters a barber shop, where the barber (Michael Palin) washes blood from his hands and acts nervous, fighting his urges to murder the customer. He tries to dissuade him from getting a haircut, and after he fails to start cutting the man's hair, he instead plays a tape recording of typical barber conversation. The customer notices, and the barber confesses that he wanted to be a lumberjack.
