How is it pronounced?

[Hookman]

So I just got around to reading The Call of Cthulu by H.P Lovecraft and something has been bugging me...How do you say it?
I've been pronouncing it Kuh-Fool-Ooh the whole time but it dawned on me that I've actually never heard it said out loud before. I realised this when I saw that I had been pronouncing R'yleh wrong the whole time. Help a brother out?

k-THOO-loo

Make the 'k' as clipped as possible.

Thanks, I know it sounds stupid but it really bugs when I don't know how names are pronounced when I'm reading.

Well, there are several different variations. You can say it any way you like, really, but the name that appears in the story is pronounced KUH-THOO-LOO

There's also:
Tulu, Clulu, Clooloo, Cthulu, Cthullu, C'thulhu, Cighulu, Cathulu, C'thlu, Kathulu, Kutulu, Kthulhu, Q?thulu, K'tulu, Kthulhut, Kulhu, Kutunluu, Ktulu, Cuitiliú, Thu Thu.

Then there's HPL's own way of saying it, the way that is supposed to be the closest to the actual pronounciation:
Khlûl'-hloo

Mmmyep. You see, it's supposed to be impossible to actually say the name, because it's so utterly alien.
