A Koala bear and a prostitute were in a motel. After very satisfying sex for both, the koala bear gets his jacket and procedes to the door. The prostitute yells, "Hey! you forgot to pay me." The koala bear looked at her with confusion. The prostitute explains..."I'm a prostitute. You have to pay me for sex." Still looking confused, the prostitute gets the dictionary and points to the word ....
