Once upon a time there were two deaf mutes standing on a street corner talking to each other with sign language.

Mute #1 (SIGN) "What would you like to do?"
Mute #2 (SIGN) "I don't know, what about you?"
Mute #1 (SIGN) "Let's get my car, find some girls, drive to a dark space and have some fun."
Mute #2 (SIGN) "Good idea."

So they get his car, find some girls, drive to a dark spot and are having a ball when the guy in the back seat taps the guy in the front seat on the shoulder...

Front Seat Mute (SIGN) "What?"
Back Seat Mute (SIGN) "Have you got any protection?"
Front Seat Mute (SIGN) "No. Don't you?"
Back Seat Mute (SIGN) "No. We had better go to a drug store and get some."

They procede to drive to a drug store and the man in the back seat gets out and goes inside. In two minutes he is back outside and taps on the car window.

Inside Mute (SIGN) "What?"
Outside Mute (SIGN) "I've got a problem."
Inside Mute (SIGN) "What?"
Outside Mute (SIGN) "I can't make the druggist understand what I want."
Inside Mute (SIGN) "I know What to do."
Outside Mute (SIGN) "What?"
Inside Mute (SIGN) "Go back inside. Put five dollars on the counter. Put your pecker on the counter. He'll know what you want."
Outside Mute (SIGN) "Good idea."

The man goes back into the drug store and two minutes later he's back at the car window.

Inside Mute (SIGN) "Well?"
Outside Mute (SIGN) "It didn't work."
Inside Mute (SIGN) "What do you mean?"
Outside Mute (SIGN) "I did what you told me to do. I went inside. I put 5 dollars on the counter. I put my pecker on the counter. He put his on the counter. It was bigger than mine. He took my 5 dollars."
