Two 80 year old men sat talking over the weather and the latest in medical
science and such, when one brings up the latest male medical miracle,
Viagra. The other wasn't familiar with Viagra and asked the first man what
it was for.
The first man said, "It's the greatest thing I've ever known. The Fountain
of Youth!! Makes you feel like a man of 30."
The second then asked, "Can you get it over the counter?"
The man looks a little taken aback but replies "You probably could, if you
took two pills".
