My wife has been having an affair with the mailman.

A couple of guys are at a bar. The first guy says to his buddy, “My wife just admitted to me that she’s been having an affair with Bob the mailman.”

“What?” says his buddy. “That fat ugly slob I see every morning outside your house?”

“That’s right,” says the first guy.

“Jesus,” says his buddy. “Why would Bob the mailman want to fuck that?”
