"Cthulhu"???? How the heck do you pronounce that? Well, humans aren't really supposed to be able to pronounce it. Cthulhu and many other hideous alien entities originated in the fantasy writings of Howard Phillips Lovecraft, a literary giant of pulp fiction and a sadly obscure character in the history of American letters. In one of his letters, Lovecraft said, "The best approximation one can make is to grunt, bark, or cough the imperfectly formed syllables Cluh-Luh with the tip of the tongue firmly affixed to the roof of the mouth. That is, if one is a human being. Directions for other entities are naturally different." Lovecraft scholars tend to say something like "Cloo-loo". Chaosium, makers of the "Call of Cthulhu" game suggest "kuh-THOOL-hoo".
