There was a koala bear who was approached by a prostitute
one day. He had never been with a prostitute before. 
Curious and excited, Koala spent the night with her and had
a GREAT time......

The next morning, he went down on her one last time before
departing.  After he's done, Koala headed for the door and
was about to leave when the prostitute yelled, "hey........
what about my money?"  Confused, the Koala turned around,
gave her a puzzled look, shrugging his shoulders, and
replied "Huh?"

"Come here....." she said and pulled a dictionary out of
her purse. She pointed to the word "prostitute" and its
definition:  "has sex and gets paid."

Finally understanding, the koala borrowed her dictionary,
turned to the word Koala and showed her its definition: 
"eats bush and leaves."
