An elderly gentleman went to the local drug store and asked the pharmacist for Viagra. The pharmacist said "That's no problem. How many do you want?"

The man answered, "Just a few, maybe four, but cut each one in four pieces."

The pharmacist said, "That won't do you any good."

The elderly gentleman said, "That's alright. I don't need them for sex anymore. I am over 80 years old. I just want it to stick out far enough so I don't piss on my shoes."
