A man is having problems with his Johnson which certainly had seen better times. He consults a doctor who, after a couple of tests, says, “Sorry, but you've overdone it the last 30 years. Your dick is burned out and you only have 30 erections left in your penis.”
Deeply depressed, he walks home. His wife is already expecting him at the front door and asks him what the doctor said concerning his problem. He tells her what the doc told him. She says, “Oh no, only 30 times! We shouldn't waste that. We should make a list!”
