An 80 year old man went to the doctor to ask for a prescription for Viagra. The doctor was a bit taken aback not only by his age but also because he was a widower. He told him he would have to have a physical first to make sure his heart, etc., was up to it. He checked out OK for a man his age, so the doctor handed him a sample package. "Lets just try a couple of pills first and see how well you tolerate it. If it works out I'll write you a prescription." The old man looked at the pills and said "Doc. Don't you have something smaller? All I want is a quarter of a pill."
