 ^^ When discussing the RMT and its actors, we might be hard-pressed to find a more classically trained, shakespeareian actor than Dr. Arnold Moss. Yet, unintentionally, he could do a "DOH" on par with the character of Homer Simpson who wouldn't be on the scene until a decade later. He did several of them in this episode, written by Dr. Moss in an adaptation of the Ambrose Bierce story which may have inspired the "Jonny Quest" creators 11 years earlier. The RMT couldn't directly "rip off" the very same sound in the "Quest" episode, but if their creature wasn't inspired by the TV cartoon version than the choice of sound effects (save the "pack of dogs" in the last attack scene) were quite a coincidence.
