This features many fourth wall breaks, such as a military man (Graham Chapman) interrupting a sketch to say to the filmmakers it was rather silly, telling them to show a sketch he wrote. As the Monty Pythons ruined the sketch, making it silly, he stops it again and shows a cartoon about the army, who got getting "just silly. And quite suspicious.", then saying "show a cartoon!" He appears many times then, such as John Cleese in many places (such as sitting at a desk or being cooked by old ladies), saying "and now, for something completely different", as they changed from a sketch to other rather different.

"Daffy Duck" who is tormented by a seemingly sadistic, initially unseen animator, who constantly changes Daffy's locations, clothing, voice, physical appearance and even shape.
