A man and his wife were sitting at a table at his ten-year high school reunion, and he kept staring at a drunken lady swigging her drink as she sat alone at a nearby table.
The wife asked, "Do you know her?"
"Yes," he sighed. "She's my old girlfriend. I understand she took to drinking right after we split up those many years ago, and I hear she hasn't been sober since."
"My God!" said his wife. "Who would think a person could go on celebrating that long?"
