A guy comes into a bar with a frog and sets it down next to the prettiest
"This is a very special frog," he informs her. "His name is Charlie."
"What's so special about this frog?" she asks.
He's reluctant to tell her, but when pressed, explains that,
"This frog can eat pussy."
The girl slaps him, knocking him off his chair, and accuses him of telling her
a filthy lie. But no, he assures her, it's completely true. And after much
discussion, she agrees to come back to his apartment to see the frog in action.
She positions herself appropriately, the guy carefully takes out the frog, and
says, "Okay, Charlie, do your stuff!" The frog is immobile, despite his
owner's exhortations, and the girl starts to snicker.
"Okay, Charlie, do your stuff!"
"C'mon Charlie, do your stuff!"
By now, the girl is laughing openly.
"Okay, Charlie," says the guy, moving the frog out of the way, "I'm
only going to show you one more time."
