And now for something completely different
Michelangelo: Good evening, your Holiness.
Pope: Evening, Michelangelo. I want to have a word with you about this painting of yours, 'The Last Supper.'
Michelangelo: Oh, yeah?
Pope: I'm not happy about it.
Michelangelo: Oh, dear. It took me hours.
Pope: Not happy at all.
Michelangelo: Is it the jellies you don't like?
Pope: No.
Michelangelo: Of course not, they add a bit of color, don't they? Oh, I know, you don't like the kangaroo?
Pope: What kangaroo?
Michelangelo: No problem, I'll paint him out.
Pope: I never saw a kangaroo!
Michelangelo: Uuh... he's right in the back. I'll paint him out! No sweat, I'll make him into a disciple.
