My best friend can spectacularly mangle certain names and words:
Album =/= alblum
McCaffrey (the author) =/= McCaferty
There are dozens of others, but I can't recall them at this moment. Those two above are the ones that make me foam at the mouth, because she'll tell you that she's SAYING it CORRECTLY, or that everybody says them that way.... I have to bite holes in my tongue and just be deaf to it. She doesn't care that saying things that poorly reflects poorly on her as a well educated woman, who COULD manage your office well, you just can't stand to listen to her! (Horribly run on sentence, but, you know what I mean!). Sadly enough, she has hideous table manners, too.
Sweet woman, great friend, but there's a lot to get past sometimes.
