The Koala Joke

So a koala meets a woman on the street, takes her back to a motel room, and proceeds to have sex with her. Afterwards, the woman turns to the Koala and says, "Okay, give me a hundred bucks."

The koala is shocked and says, "Why should I?"

The woman says, "I'm a prostitute." She tosses him a dictionary and says, "Look it up."

The Koala turns to the entry on prostitute and reads, "Person who has sex for money."

The koala tosses the dictionary back to the woman and says, "Yeah, well, I'm a Koala, look it up."

The woman is puzzled, so she quickly finds the entry for Koala:

"Furry marsupial that eats bushes and leaves."
