9. I'm Going to Explode

A: I have to go to the bathroom.

B: Why didn't you go before we left?

A: I did, but I have to go again.

B: Well, hold on a little longer.

A: I think I'm going to explode.

B: Just hold on.

A: Oh! Don't hit any more bumps!

B: We'll be at McDonald's in just a few minutes.

A: I hope they are fast minutes.

B: Think about something else. Think about a hamburger.

A: I'm thinking, but I still have to go.

B: It's the next exit. Hold on!
