Why some people don’t follow prescription

An elderly man 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 man 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.”
