I always thought the extra R's was a Texas thing...? (as in "worsh my car", and "plant some skworsh"). I believe the R's emigrated from Massachusetts, where they "pahk" their "cahh"
I have a theory that the "you all / ya'll" in Southern lingo originates from the fact that the immigrant Gaels had singular and plural form of "you" ("thu" and "sibh"). Confounded by the single english word, they started adding "all" when speaking to several people. Just my theory and I'm stickin' to it.
That's odd, El Tejon ... I have a great-grandfather that went by "Kirt". His official middle initial was "K" but I dunno what that was supposed to stand for. Worse than that, his name got passed down among some of the family as "Clark" which was quite confusing for a while until I figured out the error.
So just be glad you are not called "Clark"
You should tell folks it is "Kirk" as in "Kirk Douglas" - or doesn't anybody remember him anymore?
