One day a completely naked young lady walks into a bar. Of course, the bartender stares at her as she walks up to his bar.
"What?" says the young lass. "Haven't you seen a naked lady before?"
The bartender continues to stare at her. "Give me a beer," she says. "And stop staring like a fool!"
The bartender fetches her a brew and then answers her original question -- "Of course I have seen naked ladies before! But I was just curious as to where you'll pull the money from to pay for this beer."
