- 'Ey, here's a thought. Why don't we get an egg and start our own chicken farm? That way we'll have all the eggs we could eat.

- Right. We'll need a chicken then.

- No. No, we'll need an egg. You have the egg first. That's where you get the chicken from.

- No, that's cobblers.

- If you don't have a chicken, where you gonna get an egg?

- From the chicken that comes from the egg.

- But you have to have an egg to have a chicken.

- But you gotta get the chicken first to get the egg, and then with the egg, you get the chicken outta it.

- Hang on. Let's go over this again.

- The egg, obviously. Rollin' along, happy as Larry. Then, crack! Hatches into the first chicken.

- Yeah, but where'd the egg come from, then?

- What do you mean, where'd it come from?

- Egg comes rollin' along happy as Larry. It's wonderin', where'd it come from? Without a chicken, you get no egg to come rollin' along.

- Well, conversely, without an egg to hatch into the chicken, there will be no chicken to lay the other egg that hatches into the chicken that lays the egg I mentioned in the first place.

- So we got two eggs now?

- No, we're still talking about the very first egg.

- But what about the very first chicken?

- It's in the very first egg! Aren't you listenin'?
