The Ghost Clown first appeared in the Scooby-Doo, Where Are You! episode "Bedlam in the Big Top" as the disguise of Harry the Hypnotist. Throughout the episode, he uses a gold coin to hypnotize Daphne Blake into riding a unicycle, Norville "Shaggy" Rogers into being a lion tamer and Scooby-Doo into walking on the high wire. In the end, Shaggy and Scooby foil the Ghost Clown with mirrors.
