Why do the Mannings sound like they have a Different accent ??

We had a thread about how you pronounce New Orleans several years back. Anyone want to dig that one up? It's probably on the old board several archives ago. That was a hoot!
That's the only word that when I say it, you know I'm from there!
That and the fact that I know when you ask me "Where y'at?" I know you asking me how I'm doing, not my general location.
