Glen: Why have women never been to the moon?
Nick: I'm thinking, I have a question for you Glen, why have women never been to the moon?
Glen: 'Cause it never needed cleaning!

Glen: Why do gypsies walk funny?
Nick: Glen, why do gypsies walk funny?
Glen: 'Cause they have crystal balls!

And one from Nick:

Nick: What's the difference between unlawful and illegal Glen?
Glen: Erm, illegal is against the law and unlawful is erm, when something takes place that is not necessarily against the law...
Nick: Oh, blimey! You know this is actually supposed to be comedy now. Your answer was supposed to be, "I don't know Nick, what is the difference between unlawful and illegal?" You're crap at this, you want to stick to carpentry, mate.
Glen: Well you see I'm a very intelligent person and I'm thinking of the intellectual response to that question not the erm, comical one. OK, I'll give you the comical response now.
Nick: Let me ask you the question again: What is the difference between unlawful and illegal?
Glen: I don't know, what is the difference between unlawful and illegal?
Nick: Unlawful is against the law, and illegal is a sick bird.
