You know, it always amazes me when I see a word that I have pronounced one way for years, only to find out that I was misreading it. I have played D&D for over 20 years, and ever since the 1st Edition Monster Manual, I could have sworn that the ugly, slimy demon's name was pronounced Jubilex (joo bill ex). Now I read it and see that it is actually Juiblex? How did I read that name literally thousands of times and never catch this?
Oh, my Fav would still be Demogorgon. Makes all the other demon lords look like pansies.
