So this older guy goes to the doctor asking for a prescription for Viаgrа. The guy asks for a large dose of the strongest variety. The doctor asks why he needs so much.
The guy says that two young nymphomaniacs are spending a week at his place. The doctor fills the prescription.
Later that week, the same guy goes back to the doctor asking for pain killers. The doctor asks, "Why, is your d**k in that much pain?"
"No," says the guy, "it's for my wrists - the girls never showed up!"
