Ex Husbands

This 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 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."
