"Ya know, when I was 30 and got a hard-on,
I couldn't bend it with both hands.
By the time I was 50, I could bend it
about 10 degrees if I tried really hard.
By the time I was 60, I could bend it
about 20 degrees, no problem.
I'm gonna be 80 next week, and now I can
almost bend it in half with just one hand."
"So, what's your point?"
"Well, I'm just wondering
how much stronger I'm gonna get!"
