An 85-year-old man went to his doctor's office to get a sperm count.

The doctor gave the man a jar and said, "Take this jar home and bring
back 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 on the previous day.

The doctor asked what happened and the man explained, "Well, doc, it's
like this - First I tried with my right hand, but nothing. Then I tried
with my left hand, but still nothing. Then I asked my wife for help. She
tried with her right hand, then her left, still nothing. She tried with
her mouth, first with the teeth in, then with her teeth out, and still
nothing. We even called up Arleen, the lady next door and she tried too,
first with both hands, then an armpit and she even tried squeezin' it
between her knees, but still nothing."

The doctor was shocked!  "You asked your neighbor?"

The old man replied, "Yep. And no matter what we tried, we still
couldn't get the jar open."

"Many more men die with prostate cancer than of it. Growing old is
invariably fatal. Prostate cancer is only sometimes so."
