An elderly gentleman went to see his doctor and asked for a prescription of Viagra. The doctor 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 doctor 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 am over 90 years old. I just want it to stick out far enough so I don’t pee on my shoes.”
