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."
