A nod is given to the Tin-Man, Scarecrow and the Cowardly Lion as the woman packs her suitcase. Inside the suitcase sits a book by Nietzsche - philosophy for the scarecrow (if he only had a brain). To this is added a booked called "How To Find Your Courage" - for the Cowardly Lion. The suitcase zip then sticks and she uses some WD-40 to release it - oil for the Tin-Man.
