A wee old man went into a chemist to buy Viagra.
“Can I have 6 tablets,” he asked, “and can you cut them into quarters for me?”
“I can cut them into quarters sir,” said the chemist, “but a quarter won’t give you a full erection.”
“I’m 96,” said the old man, ‘and I don’t have any use for an erection. I just want it sticking out far enough so I don’t piss on my slippers!”
