What words do your teachers pronounce wrong?

Last year my chemistry teacher said "nuculus" and now I have to think about it every time I say it. This year my chemistry teacher pronounces "ion" like "iron" (eye-un rather than eye-on). My biology teacher pronounces "protist" as "proticist". My geography teacher can't decide whether to say "glacier" (with an a like apple) or "glaycier" so she pronounces it differently every time. Obviously not hating on ppl for mispronouncing stuff, but do your teachers have any words like this?
