Erin - do you pronounce mom as mum? I used to date a guy from pittsburgh and that's how he pronounced mom...drove me bonkers!
I say Mum too. But my mum is British and thats how they say it. They also spell it Mum instead of Mom though.
I had a Japanese math teacher once who always said calculator "cal-ick-u-lator", it was so funny and cute that my friends and I all started saying it and it has stuck.
My bf says "viet-man-ese", instead of vietnamese and it drives me crazy.
It bugs me when other people say "pellow" instead of "pillow" and "melk" instead of "milk."
Oh, I hate that too! I also hate when people say EL-ih-noy. There's no E in Illinois! (I've heard several people do this, maybe it's a SE Wisconsin thing?)
I'm guilty of sherbert, joolery, coo-pon. Up until a few years ago, I totally thought geisha was pronounced geesha.
My roommate is constantly pronouncing things wrong and it bothers me so much! For example, there's a street a few blocks from where I live called Ogden St. She prounounces it oge-den, instead of og-den.

Now the name of a frozen dessert, the word sherbet appeared in English in the seventeenth century, meaning a cold fruit drink, and developed two spellings reflecting its two pronunciations, sherbet (SHUHR-bit) and sherbert (SHUHR-buhrt). Today both spellings and both pronunciations are regularly encountered in both British and American use, to the discomfort of some purists, who argue that only sherbet is acceptable. Meantime, food fanciers have reborrowed this word in its French form, sorbet, pronounced both in the French way (sor-BAI) and an anglicized (SOR-bet). Standard English now uses all three forms, although Edited English usually clings to sherbet and continues to italicize the French sorbet as foreign. Australian English now uses sherbert, both alone and in compounds, as another name for beer.
So I think you're okay no matter which way you say it.
