Ole and Lena were sitting at a table at her high school reunion, and Lena kept staring at a drunken man swigging his drink as he sat alone at a nearby table.
Ole asks, "Do you know him?"
"Yes," Lena sighed, "He's my old boyfriend. I understand he took to drinking right after we split up those many years ago, and I hear he hasn't been sober since."
"My God!" says Ole, "Who could believe a person could go on celebrating that long?"
