A young couple is out carousing one evening. While driving down the 
highway the guy says to the girl,

"If I go 100 miles an hour, will you take off your clothes?" 
     
She agrees and he begins to speed up. When the spedometer hits 100 she 
starts to strip. When she gets all her clothes off he is so busy staring
at her that he drives off the road and flips the car. The girl
is thrown clear without a scratch but her clothes and her boyfriend 
are trapped in the car. "Go get help.", he pleads.      

She replies, "I can't, I'm naked." 
     
He points to his shoe that was thrown clear and says "Cover your 
snatch with that and go get help." 
     
She takes the shoe, covers herself, and runs to the gas station down 
the road. When she arrives she is frantic and yells to the attendant,
"HELP! HELP! My boyfriend's stuck!" 
     
The attendant looks down at the shoe covering her crotch and replies, 
"I'm sorry Miss. He's too far in."
