What's with the Accent?

[Jentleness]

I'm from California, we don't have accents.

That's silly, of course we do!!! We have Californian accents!!!

... southern accents tend to slip into those too, but "warsh"? How do you get "warsh" out of wash?

I heard once that the "r" comes from New Yorkers, what happens is when they speak the "r" gets launched into the atmosphere (which is why they never pronounce the "r" when they speak) and then rains down on West Virginia and ends up in words like wash!
