Two Elderly Gentlemen...

...from a retirement center were sitting on a bench under a tree when one turns to the other and says: 'Slim, I'm 83 years old now and I'm just full of aches and pains. I know you're about my age. How do you feel?'

Slim says, 'I feel just like a newborn baby.'

'Really!? Like a newborn baby!?'

'Yep. No hair, no teeth, and I think I just wet my pants.'
