yet another Viagra joke

Two 80-year-old men sat talking about the latest advances in medical science.

One brings up the medical miracle, Viagra.

The other elderly man isn't familiar with Viagra, and asks the first man, "What's it for?"

The first man says, "It's the greatest thing I've ever known. The Fountain of Youth! Makes you feel like a man of thirty."

The second asks, "Can you get it over the counter?"

"You probably could," replies the first, "if you took enough."
