Cthulhu; It is said the proper pronunciation is "Koo-Too-Loo"
Cthulhu's name is usually pronounced /ku'tu'hlu/, or /ku'thul'lu/, or /Chattanooga Choochoo/
however, according to Lovecraft, this may simply be the closest that human vocal cords can come to reproducing the syllables of an alien language. In fact, Lovecraft speculated that "Khlul'hloo" might be a better pronunciation.
or if you are feeling suicidal "cho-chee, cho-chee, chooo".
ahhh .... it's sooo cute!
