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 won't do you any good."

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