This episode has a stern governess named Treadwell, and a man named Bert who draws chalk pictures on the pavement to entertain passersby. One might even think that "Treadwell" is a reference to "Travers" (traverse). A sly reference to Mary Poppins (1964). Miss Treadwell also references Miss Gulch from The Wizard of Oz (1939) as a stern woman who wants to put a young woman's dog to death.
