You would think that after fellow SCTV alumni Martin Short & Joe Flaherty had bombed just a couple of years earlier with The Completely Mental Misadventures of Ed Grimley, Rick Moranis would've thought twice about doing a Saturday morning cartoon. Instead, he agreed to lend his voice and likeness to Gravedale High, which, like Ed Grimley and SCTV, aired on NBC. Umbrellagecko uploaded the open to YouTube, which features Rick joining the cast in singing the title song:
Gravedale High, like Ed Grimley, lasted just one season. Viewers just didn't warm up to an all-ghoul high school. Oh, by the way, Hanna-Barbera produced both Ed Grimley & Gravedale High, the latter in conjunction with NBC, which thought Gravedale might fit in with its developing line of live-action teen sitcoms. I believe NBC-Universal owns the show now, which is why you probably will never see it on Cartoon Network.
