Nick: Here's a thought. Why don't we get an egg and start our own chicken farm? That way we'd have all the eggs we could eat.

Nick: No... no, we'll need an egg. You have the egg first, that's where you get the chicken from.

Fetcher: No, that's cobblers. If you don't have a chicken, where are you going to get the egg?

Nick: From the chicken that comes from the egg.

Fetcher: Yeah, but you have to have an egg to have a chicken.

Nick: Yeah, but you've got to get the chicken first to get the egg, and then you get the egg... to get the chicken out of...

Fetcher: Hang on, let's go over this again.
