The pharmacist reaches under the counter and removes a brown box with an "X" on it. "Here. If you eat this you'll go wild and nuts!!"
"Great!" the guys says, "Give me three of them!"
The next day the guy comes back into the pharmacy. He drops his pants and the pharmacist looks in horror at the guys penis. It's black and blue, and the skin is hanging off of it. "That X stuff was great but now I need some Ben-Gay!!" He shouted!
"You're not going to put Ben-Gay on that are you?" asked the pharmacist.
"Hell no!!" was the reply. "It's for my arms. The girls never showed up!!"
