45. Broken Window

A: My son broke a window yesterday.

B: How did he do that?

A: He said he was practicing his pitching.

B: He was pitching against the window?

A: No, against the side of the house.

B: If he missed, he's not a very good pitcher.

A: No, but he's pretty fast and can run long distances.

B: How do you know that?

A: I chased him when I found out he broke the window.

B: Well, you contributed to his training.

A: As his coach, my fee is three months of his allowance.

B: What a coincidence!

That's enough for a new window.
