A man is having problems with his penis, which certainly has seen better times.

He consults a doctor who, after a couple of tests, says, "Sorry, but you've overdone it for the past 30 years. Your penis is burned out. You only have 30 erections left."

The man walks home, deeply depressed. His wife is waiting for him at the front door and asks him what the doctor said concerning his problem. He tells her what the doctor told him.

She says, "Oh, no, only 30 times! We shouldn't waste that. We should make a list!"

He replies, "Yes, I already made a list on the way home. Sorry, your name isn't on it."
