The same doctor prescribed the same medication to a man who said that he had a date with twin nymphomaniacs so needed the strongest pill available.  The doctor prescribed a double dose of what he'd given the other couple.  The pharmacist filled the prescription but warned the man to be careful.  The next day he went back to the pharmacist and told him about the previous night. "I was hornier than I've ever been.  I was going crazy, actually chewed up my pillow and did a lot of yelling and screaming.  And I was hard for hours, literally hours.  But now I have another problem."  He took out his Johnson and it was raw, red and bleeding.  "I need some Ben Gay." he said.  The pharmacist told him that Ben Gay would surely make his pecker scream, in pain.  "Oh, it's not for that," he said, "it's for my arms.  The girls never showed up last night."
