A guy 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. I need something to keep me ready and 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 twelve hours."
The guy says, "Gimme three boxes."
The next day, the guy walks into the same pharmacy, limps up to the pharmacist and pulls down his pants. The pharmacist looks in horror as he notices the man's ‘member’ is black and blue, mangled and chunks of skin are hanging off in some places.
In a pained voice, the man moans out, "Gimme a bottle of Deep Heat."
The pharmacist replies in horror, "You can't put Deep Heat on that!"
The man replies, "No, it's for my arms, the girls didn't show up."
