Strongest But Useless Viagra…

This older guy went to the doctor asking for a prescription for Viagra. The guy asked for a large dose of the strongest variety. The doctor asked 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 came back to the doctor for pain killers. The doctor asked 'why, is your dick in that much pain?' 'no', said the guy, 'it's for my wrists - the girls never showed up!'
