We have a surprise visit from Scooby fan Kenny Biddle, then speak with Mark Norman, folklorist and author of the upcoming "Zoinks!: The Spooky Folklore of Scooby Doo." The show is beloved by skeptics, and for good reason. But did you know the show owes its existence to a panic in the 1960s about violence in kids' shows? Between guest stars like the Harlem Globetrotters and Vincent Price, Scooby Doo also introduced kids to a wide array of cryptids, ghosts, witches and folkloric concepts like curses, mysterious mirrors, and of course haunted houses. The show itself has also become the subject of a few urban legends and modern myths, from Shaggy's alleged drug use to the characters representing Massachusetts colleges.
