Actually Tegan, it was Tony the Tiger (he's grrrrrrrreat!) who sang "You're a Mean One, Mr. Grinch" in the animated version (Boris Karloff narrated and provided the Grinch's speaking voice). It wasn't supposed to be the Grinch singing about himself. That was one of the many little things that added up to me not loving the Jim Carrey version. I didn't hate it, but it's a pretty good example of why you just shouldn't tamper with a classic.

I still think Tim Curry would have made a kick-ass Grinch.
