Tony the Tiger, R.I.P.

Well, okay, not exactly the Frosted Flakes cartoon character. But that was the voice that Thurl Ravenscroft was most famous for.

Thurl did a lot of voices you're probably familiar with. If you've ever been to the Haunted Mansion at the Disney theme parks, it's Thurl who sings the Mansion's theme song (Grimbling Ghosts, About to Socialize). He also sang "You're A Mean One, Mister Grinch" in the Chuck Jones classic How the Grinch Stole Christmas.

But it's the Tony the Tiger yell he's most famous for: "They're GRRRRRRRREAT!"

The only other bass voice with that kind of range is James Earl Jones. But somehow, the idea of the voice of Darth Vader shilling breakfast cereal is a little, er, disconcerting.

Thurl Ravenscroft passed away from prostate cancer on Sunday, at the age of 91.
