Schick is walking down the boardwalk in Atlantic City, runs into a hooker,
and he says, "How much?"
She says, "Twenty bucks."
He says, "All right."
They climb down under the boardwalk, and he bangs her.  The next night, he
runs into the same hooker, they go under the boardwalk, only this time 
while he's banging her, she blasts two incredible farts.  When they get 
done, he hands her twenty-FIVE dollars.
She says, "What the extra five?"
He says, "That's for blowing the sand off my balls."
