From Monty Python's The Life of Brian:

• Nisus Wettus Crucifixion?
• Mr. Cheeky Ah, no. Freedom.
• Nisus Wettus What?
• Mr. Cheeky Eh, freedom for me. They said I hadn't done anything, so I can go free and live on an island somewhere.
• Nisus Wettus Oh, oh that´s jolly good well. Off you go then.
• Mr. Cheeky No, I'm only pulling your leg, it's crucifixion really!
• Nisus Wettus [laughing] Oh, I see, very good. Well...
• Mr. Cheeky Yes I know, out the door, one cross each, line on the left.
