Synopsis[]
A man (Michael Palin) tells his wife (Terry Jones) that he has received a letter from the BBC asking him to be in a sketch, his job to be standing at a counter until the sketch starts. She tells him that this is called a "walk-on." A robber (John Cleese) and an assistant (Eric Idle) wait for him at the shop where the sketch is to be filmed. The wife watches live on television as the husband does his part in the sketch.
