A couple is sitting in a restaurant and the husband sees that his wife keeps looking over at a thoroughly besotted fellow at a nearby table.
"I notice that you keep looking over at that poor fellow. Do you know him?"
"Yes," says the woman, "he's my ex-husband I told you about, and he's been drinking like that ever since I left him seven years ago."
"That's remarkable," her companion says. "I didn't think anyone could celebrate that long."
