Two old men are sitting in a bar when the first one says, "Ya know, when I was thirty and got an erection, 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?"
