Yeah, but I thought he was drawing a parallel between Wizard of Oz and something else, i.e. Elsa is the wicked witch of the East. If it's older than Frozen, then it's probably not that!
They were playing a game of Hedbanz / Headbands / Celebrity , and one of them had The Good Witch Glinda from Wizard of Oz as their character, and they are arguing about them not guessing it based on the clues.
