In case you missed it, zombie originator George Romero (the creatures were his creation in Night of the Living Dead) was a guest on the Halloween edition of NPR fave Wait Wait ... Don't Tell Me! He shared this interesting factoid: Romero got his start working with Fred Rogers on the Mister Rogers episode, "Let's Talk About Going to the Hospital," in which a little girl gets a tonsillectomy.
