A man and his wife are dining at a table in a plush restaurant, and the wife keeps staring at an old drunken man swigging his gin as he sits alone at a nearby table, until the husband asks, "Do you know him?" "Yes," sighs the wife, "He's my ex-husband. He took to drinking right after we divorced seven years ago, and I hear he hasn't been sober since." "My God!" says the husband, "Who would think a person could go on celebrating that long?"
