A man and his wife are dining at a table in a plush restaurant, and the husband keeps staring at a drunken lady swigging her drink as she sits alone at a nearby table, with a big smile on her face. The wife asks, "Do you know her?" "Yes," sighs the husband, "She's my ex-girlfriend. I understand she took to drinking right after we split up seven years ago, and I hear she hasn't been sober since." "My God!" says the wife, "Who would think a person could go on celebrating that long???"
