Old girlfriend

My wife and I were sitting at a table at my high school reunion, and I kept staring at a drunken lady swigging her drink as she sat alone at a nearby table. My wife asks, "Do you know her?"

"Yes," I 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!" says my wife, "Who would think a person could go on celebrating that long?"
