A married couple were sitting in a fine restaurant when the wife looks over at a nearby table and sees a man in a drunken stupor.
Her 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, "Who would have thought anybody could celebrate that long."
