Why did the chicken cross the road?

William Lane Craig: In the wake of your new book, Chicken Physics–published by Bantam Press (pardon the pun)–I'd like to ask you a question or two. For starters, "Why did the chicken cross the road?"

Lawrence Krauss: That's the sort of deceptive, prejudicial question I've come to expect from Bible-thumpers like you.

Craig: Why do you say that?

Krauss: It begs the question by assuming there was a reason the chicken crossed the road.

Craig: What's wrong with that question?

Krauss: Because nothing caused the chicken to cross the road. 

Craig: Nothing at all?

Krauss: That's right. 

Craig: So how did it get from one side of the road to the the other side?

Krauss: It just popped out of a quantum vacuum. 

Craig: Is that anything like a Hoover vacuum? 

Krauss: Nothing is not like anything. That's the point.

Craig: Very well. Permit me to ask you another question: "Which came first: the chicken or the egg?"

Krauss: There you go again with your loaded questions! One didn't come before the other. Rather, both popped right out of the quantum vacuum.

Craig: That's a mighty impressive vacuum. Almost like pulling rabbits out of the hat.

Krauss: If I didn't know better, I'd say the quantum vacuum has godlike powers.
