"Crappie", because I made it past 2nd grade, where I learned how to pronounce words based on how they're spelled, and the use of the vowels and nouns. Never understood how you get "crop-pee" out of "crappie(crap-pee)".
I do find my self saying sac a laits a lot, and I've only passed through LA a couple times in my life. It's just a fun word.
