1x7 - Scooby-Doo: Behind the Scenes

One of the Scare Pair, the Gypsy and the Witch Doctor all claim to have been the first to refer to the gang as "those meddling kids". From within a jail cell, the Cat Creature explains that the key to being a good villain is the "hidden door". The Ghost Clown admits that he'd been "groomed to be an astronaut". Dr. Najib, the Black Knight (still stuck in the pillory) and the Headless Specter are all given a chance to give their true feelings on the gang, but appear hesitant to really say much of substance.
