I've got one Deacon_Blues can appreciate.
Most Americans I know pronounce the word "sauna" as "sana" (forgetting the U glide in there). I tell them that "sana" is actually a word in Finnish (meaning, ironically enough, "word"), but not the one people think they are saying when they attempt to pronounce "sauna."
In the local accent in western Louisiana, we get lots of "aks" instead of ask. Add to that, we get things like "dest" instead of desk. There are several others like this which sound strange to my ears, but I can't think of examples now.
One that I get is that the place where I work (a library) is renamed as a "lie-berry". Borrow becomes "borry". Oh, and the "pacific" instead of specific one... hear that a LOT! Irritating, too.
My dad last year got diagnosed with prostate cancer, but ever single time he talked about it it was "prostrate". That's a simple word mix-up, of course, but still... (And no, I didn't correct him. He wouldn't really appreciate it.)
