An old man goes into a drug store to buy some Viagra.

"Can I have 6 tablets, cut in quarters?"

"I can cut them for you," said the pharmacist, "but a quarter tablet will not give you a full erection."

"I am 96", said the old man.

"I don't want an erection!"

"I just want it sticking out far enough so I don't pee on my slippers!"
