You know, there's one OTHER Snow White Parody I've seen, years ago. Months, actually. It was called "Cute First, Ask Questions Later," a FABULOUSLY Cheap Cartoon, that was like an extended version of the Snow White Story, where Snow White becomes evil, intent on being the cutest in the land, and she orders the TWO Dwarves to capture Dot, the Cute One! It had Dennis Hopper doing that "You're cute" thing, man! And it had such a FABULOUSLY Annoying narrator!
