Ben Gay

This guy walks into a pharmacy and says to the pharmacist "Listen, I have 3 girls coming over tonight. I never had 3 girls at once, I need something to keep me horny, keep me potent."

So the pharmacist reaches under the counter, unlocks the bottom drawer and takes out a small black cardboard box marked with an "X" and says "Here, if you eat this you'll go NUTS for 12 hours!"

The guy says "gimmee 3 boxes".

Same guy walks into the same pharmacy, right up to the same pharmacist and pulls down his pants. The pharmacist looks in horror as he notices the man's dick is black blue, the skin's hanging off in places. The man says "gimmee a bottle of Ben Gay."

To which the pharmacist replies "Ben Gay? You're not going to put BEN GAY on that are you?"

The guy says, "No it's for my arms, the girls didn't show up".
