Husband：The Blacks got divorced。

Wife：Really? Why?

Husband：Mr. Black has been getting a little on the side。

Wife：I’m surprised. He doesn’t look like a guy who’d ever cheat on his wife, does he?

Husband：No, he doesn’t. But his wife found out that he's been two-timing for a long time. Incredibly, he’s had many different girlfriends starting almost right after they got married 20 years ago。

Wife：Well, I'm really surprised. You’re not doing anything behind my back, are you?

Husband：No. The only thing I’ve ever done behind your back is zip you up. Besides, I told all my other girlfriends that my wife was getting suspicious and that we had to cool it for a while until the smoke blew over。

Wife：Ha! Ha! You’re not very funny. I guess that means you expect me to tell my lover we have to stop seeing each other too。

Husband：You’re not funny either. I can’t believe I married a woman like you。
