Copperhead walks into a drug store and says to the Pharmacist behind the counter,

'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 chemist reaches under the counter, unlocks the bottom drawer and takes out a small cardboard box marked with the label Vi@gra Extra Strength and says, 'If you take this, you'll go ****** for 12 hours.'

Very happy and excited, Copperhead says, 'Gimme three boxes.'

The next day Copperhead walks into the same drug store, right up to the same Pharmacist and pulls down his pants. The chemist looks in horror as he notices Copperhead's c**k is swollen, black and blue, and the skin is hanging off in some places.

Copperhead says, 'Gimme a tube of Deep Heat.'

The Pharmacist replies, 'Deep Heat? You're not going to put Deep Heat on that are you?'

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