An old man hobbles down the aisle to meet the pharmacist. “I would like to buy some Viagra please”, he says, hands shaking and reaching the counter for support.

The pharmacist is surprised and questions, “You look like in no shape to get into the love making act. Why do you want Viagra?”

The old man replies, “No, No. It is not for the bedroom. I want to take this so that I can stop peeing on my slippers.”
