A man in his 40s goes in for a physical. The doctor says "I have good news and I have bad news."

The man says, "Give me the bad news first." Doc says, "There is a problem with your penis, you can only get a few more erections, and then you won't have any more for the rest of your life."

The man says, "What in the world is the good news?"

Doc says, "We know the number is exactly 25, so you can plan your use of them accordingly."

The man leaves and drives around for a couple hours pondering his situation, and how to confront his wife. When he gets home he tells her, "Honey, I have good news, and I have bad news." She says, "Give me the good news." He says, "I can only have 25 more erections, and then I can't have any more, ever."

She says, "We can work around that, we will just make a list and only use them when it is absolutely necessary to fulfill our desires, and make the most out of each one, what in the world is the bad news?"

He says, "I already made a list, and you aren't on it.."
