A man and his wife are dining at a table in a plush restaurant, and the husband keeps staring at an old drunken lady swigging her gin as she sits alone at a nearby table, until the wife asks,
"Do you know her?"
"Yes," sighs the husband, "She's my ex-wife. She took to drinking right after we divorced 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?"
