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, and I need something to keep me horny...or keep me potent,
that is."

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 goes up to
the pharmacist and pulls down his pants. The pharmacist looks in
horror as he notices the man's jewels are black and blue, and the
skin is hanging off his penis in some places.

The man says, "Gimme a big can of Ralgex"

The pharmacist replies, "Ralgex? You're not going to put Ralgex
on that, are you?!"

The man says, "No, it's for my arms... the girls never showed up."
