An 80 year old man sees a Urologist. At the end of the visit, the doctor hands him a jar and tells him he wants him to come back tomorrow with a semen sample.
The old man comes back the next day in the jar is empty. So the doctor asks him what happened?
" well doc, I tried with my left hand... nothing. I tried with my right hand.. nothing. I tried with both hands.. nothing. I went to my wife for help.. nothing. So I went next door to my neighbor Gladys for help.. nothing."
The doc says, hold up. You went to your neighbor Gladys for help?
" yeah! None of us could get the lid off of that damn jar!"
