A guy is walking down the boardwalk in Atlantic City when he runs into a hooker.

"How much?" he asks.

"$20," she says

"OK," he says and they climb down under the boardwalk, where he bangs her. The next night, he runs into the same hooker and they go under the boardwalk again, only this time, while he's banging her, she blasts two incredible farts.

When they get done, he hands her $25.

"What's the extra five?" she asks.

"That's for blowing the sand off my balls."
