A couple are dining in a small restaurant. The husband notices that the wife is staring over his shoulder at a wall table behind him. He is naturally curious and looks around. He sees a guy sprawled in his chair and with his head on the table, clutching a glass of whisky, dead to the world.

The wife tells him: " That's my ex-husband whom I divorced 12 years ago".

The guy says in a musing tone of voice: " "Gee. I never realized that anyone could celebrate that long."
