Two old geezers are sitting in a bar when the first one says, "Ya know, when I was thirty and got a hard-on, I couldn't bend it, even using both hands. By the time I was forty, I could bend it about ten degrees if I tried really hard. By the time I was fifty, I could bend it about twenty degrees, no problem. I'm gonna be sixty next week, and now I can bend it in half with just one hand."

"So," says the second drunk, "what's your point?"

"Well, I'm just wondering how much stronger I'm gonna get?"
