The next story about adventures of famous Koala!

Do you remember the famous Koala? I've heard another funny joke about him recently:

The Koala walks into a pub reads a menu above the table:
"Sandwich 2$
Beer 5$
Hand job 4$"

After that the Koala comes to the hot woman behind the table. The girl was very hot, more beautiful than the prostitute. The Koala asks her - Excuse me, are you the one who does the hand job?
She smiles at him and answers - Yes!
Then the Koala replies - Can you wash your hands? I'd like to buy a ham sandwich, please.
