I've waited a long time for this one, another piece that was previously here but deleted from YouTube due to copyright issues. Dailymotion seems to be a safe haven for videos that YouTube can't hang on to.
Case in point, "The Nutcracker Scoob" episode of The New Scooby-Doo Mysteries.
Fred (Frank Welker) returns for this episode, one of several appearances he'd make during the season. Y'don't suppose that might be to ensure there is no chance at Shaggy & Daphne getting close, do you? And, man, don't ya think they could've used him for the later 13 Ghosts series?
