Joke

Two old guys 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 his buddy, ‘what's your point?’
‘Well, I'm just wondering how much stronger I'm gonna get.’
