Biker

Crazy Mike the Biker walks into a pharmacy and says to the pharmacist, "Listen, I have three girls coming over tonight. I've never had three girls at once, and I need something to keep me horny ... keep me potent."

The pharmacist reaches under the counter, unlocks the bottom drawer and takes out a small cardboard box marked with a label "Viagra Extra Strength" and says, "Here, if you eat this, you'll go NUTS for 12 hours!"

Then Crazy Mike says, "Gimme 3 boxes."

The next day, Crazy Mike 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 pens is black and blue, and the skin is hanging off in some places. Crazy Mike says, "Gimme a bottle of Ben Gay."

The pharmacist replies, "BEN GAY?!?!?! You're not going to put Ben Gay on that, are you?"

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