Look It Up
A koala bear walks into a bar. He asks the bartender how he can get a little action for the night. The bartender points to a cute little trick at the end of the bar. So the koala bear walks up to her and in a few minutes they're heading to her place. When they get they're the koala bear immediately goes down on her. After a few minutes he jumps up and splits.
The next night, the woman spots the koala bear at the bar again and confronts him saying: "You owe me money!" "For what?" the koala asks. The woman rolls her eyes and tells him, "I'm a prostitute." The koala bear pulls out a dictionary and looks it up: "Prostitute: Has sex for money." The koala says, "I don't owe you a thing. I'm a koala bear. Look it up." Before she can protest the koala hands her the dictionary.
The woman looks up "koala bear" and reads, "Koala bear: Eats bush and leaves.”
