Doubt I've ever heard the term "kitty corner" either. I've heard caddy wampus, but I'm guessing that is catty wampus.
Like when they tell you to sound out the word to spell it. Well what if you don't even know how to say it?
I have heard people say both crick and creek.
In Canada they say creek eh.
I visited my uncle in UP Michigan once and by the end of the week I was ending everything with eh. They say folks from Ohio don't really have an accent.
