The Blacks got divorced.
Really? Why?
Mr. Black has been getting a little on the side.
Really? I am surprised. He doesn't look like a guy who'd ever cheat on his wife, does he?
No, he doesn't. Anyway, his wife found out that he has been two-timing for a long time.
Well, I am really surprised. By the way, have you done anything behind my back?
No. The only thing I've ever done behind your back is zipping you up.
I like that joke, but I hope it's true.
