It was very funny to me, and also not surprising, that the scene was used in an article titled “How Do You Know She’s a Witch?”: Witches, Cunning Folk, and Competition in Denmark" in the journal Western Folklore (v.59 no.3/4, 2000):
Already in the seventeenth question, “How do you know she’s a witch?” is not, “She turned me into a newt,” or some other example of physically verifiable maleficium, but rather, “Because I say so.”
