The Best Part of Waking Up Is Cthulhu Attacking a British Game Show

Countdown is a British game show involving word and number puzzles. It does not, generally, involve Cthulhu, at least until a contestant gets a very unfortunate selection of letters to decipher — as shown here in this a wonderfully violent, The Thing-inspired, CG animated, fan video. My question is, why hasn’t this happened on Wheel of Fortune yet?
