The Ruby Slippers - Wizard of Oz (1939)
Quick, what's the first incidence of someone killing a person and stealing their shoes? Long before Nike and Reebok were making $200 kicks, Dorothy was jacking ruby slippers from a dead witch. We love the ruby slippers! They are one of the first "cursed objects," where the wearer can't remove them and gets a heap of trouble. But upon rewatching, we can't help but wonder: What was the point?
According to Glenda, the "Good" Witch, the ruby slippers have two uses: Protecting Dorothy and sending her home. "Never let those ruby slippers off your feet for a moment, or you will be at the mercy of the Wicked Witch of the West," advises Glenda. Sounds like good advice ... except the reason why the Wicked Witch is after Dorothy in the first place is because Dorothy is wearing the ruby slippers. Plus, they really don't seem to be any good at keeping flying monkeys at bay, so we're not sure what Glenda was talking about.
The big payoff comes at the end of the film, when Dorothy learns the slippers can send her home. Well, that's actually useful ... except we count three other ways Dorothy could have gone home at that point: Balloon, Glenda using her magic to help Dorothy get home, or just waking up.
So what were the shoes good for? They gain Dorothy entrance to the Wizard's castle. The door guard should have just said, "Oh, you're wearing shoes from a corpse? That's our Glenda all right: Too cheap to buy business cards or call ahead!"
