Ex-Spouse

A married couple was sitting in a fine restaurant when the wife looks over at a nearby table and sees a man in a drunken stupor.  The husband asks, "I notice you've been watching that man for some time now. Do you know him?"

"Yes," she replies. "He's my ex-husband, and he has been drinking like that since I left him seven years ago."

"That's remarkable," the husband replies. "I wouldn't think anybody could celebrate that long."
