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 4, but cut each one in 4 pieces."

The pharmacist said "That wont do you any good."

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