I hear that one a lot. And the ol dubya standby, "nucular" -- my husband says that too, and he's from Missouri!

The one that drives me craziest is "groshery" -- but that error is often replicated with "speshies" instead of "species," and I've heard that one from folks that were from everywhere, even Canada -- Alex Trebek says "speshies"!
The thing to keep in mind is that yes, some southerners do talk kinda funny, but many are brilliant, college-educated people -- Jimmy Carter, Bill Clinton, just to name a couple of examples that leap to mind immediately, but there are a GREAT many others. There are probably also brilliant, college-educated people whose accents place their origins as NYC or "joysey".
