I was kind of surprised that they left out yinz. I was going to mention it, but I figured someone else already did. There was a show on regional accents on PBS and they compared western PA to the Galapagos Islands of regional accents. I mean get aht!

Some natives of Bloomington, Indiana do that one, too.

Some people in North Carolina use what seems to be a subtle variation from that... it comes out "you'uns". It's been a while since I heard anybody say that, though. I think it's more of a country thing.
