A couple of old guys sat at the bar... Ernest pops up with a comment ""George, when I was 20 years old and I had a hard-on, I couldn't bend it with both hands!"" They sit in silence a few minutes, punctuated by the occasional sip. Ernest says ""When I was 35, I could bend it with one hand."" A few minutes later, he says ""Now I can bend it with one finger!"" Another few sips and he says ""George, how much stronger do you think I'm gonna get?""
