An elderly gentleman went to the local drug store and asked the pharmacist to fill his prescription for Viagra. "How many do you want?" asked the pharmacist.

The man replied, "Just a few, maybe half a dozen. I cut each one into four pieces."

Upon hearing that, the pharmacist said, "That's too small a dose. That won't get you through sex."

The old fellow said, "Oh, I'm past ninety years old and I don't even think about sex anymore. I just want it to stick out enough so I don't pee on my shoes."
