Two old drunks were drinking in the pub together, when the first one says:
"You know, Mick, when I was 30 and got a hard-on, I couldn't bend it with both hands. When I was 40, I could bend it about 10 degrees if I tried really hard.
By the time I was 50, I could bend it about 20 degrees, no problem. I'm 60 next week and now I can almost bend it in half with just one hand."
"So, " says the second drunk, "What's your point?"
"The point is, I'm just wondering how much stronger I'm going to get."
