An 85 year-old man was requested,by his doctor for a sperm count as part of his physical exam.
The doctor gave the man a jar and said Take it home and bring it back with a semen sample tomorrow.
The next day the 85 year-old man reappeared at the doctor's office and gave him the jar,which was as clean and empty as the previouvs day.
The doctor asked him what happened and the man explained,well doc I tried with my right hand,but nothing happened,so I tried with my left hand but still noyhing happened.
Then I asked my wife for some help. She tried with her right hand,then with her left hand and still nothing.
She tried with her mouth,first with her teeth in,then with her teeth out,still noyhing.
We even called up Arleen,the lady next door and she tried too,first with her hands and then with her mouth,still nothing.
The doctor was shocked,yes ask the neighbor too?
The old man replied,"Yep,none uf us could get the jar open".
