If you children are bad, or if you answer a problem wrong, I'll wiggle my ears, stick out my tongue, and turn you into apples!
~ Mrs. Gorf

Mrs. Gorf is a teacher in the Wayside School children's books. She hates children and punishes them by turning them into apples. Eventually, one of her students holds up a mirror and she turns herself into an apple. Louis then eats her unknowingly.

After her death, Mrs. Gorf's continues to haunt Wayside School, and her former students occasionally see her. Her son, who has a third nostril, appears as a substitute teacher and gets revenge on her former students by stealing their voices.
