Two guys in their mid-twenties are sitting at a bar having a beer.

One of the guys remarks to the other, “Boy you look really tired!”

Dude, I’m exhausted, my girlfriend wants sex all the time! Three, four, sometimes even six times a night! She wakes me up at all hours. I just don’t know what to do!”

A fellow, in his seventies, is sitting a few bar stools down from them and overhears their conversation. He looked over at the two men, and showing the wisdom of his age says,

“Marry her. That’ll put an end to that nonsense!”
