I don’t care if that’s original to you or not, that’s funny.
But is it original to you?
Long ago when my folks lived in Virginia, they had a neighbor, Ronnie, who was from a southern state and had a pronounced drawl. As the story goes, little Ronnie asked my mom one evening,“Whatcha havin’ for supper?”
She told him, then asked, “What are you having?”
“Bikkits n’ gry-vee.” (Biscuits and gravy)
It’s funny to this day.
On another note, is it common for people in Michigan to say" You was" and “You wasn’t” or is this just something my PA-born aunt does?
I doubt it. I’ve been saying it for so long that I can’t recall what made me start saying it, though.
I know the first time I heard it was in context with the migration of the letter r from the north to the south.
As in:
Paak the caa.
or
Warsh yer socks.
There’s no such thing as an original idea, though. 
Not extra syllables, but I remember my grandmother from Queens/Brooklyn reversing mispronunciations when referring to our erl boina…
How about ditn’t, cutn’t wutn’t that is common in some black dialects. Condy Rice used them frequently, as well as pronouncing United States as “U-nye-nit States”.
Another pronunciation quirk, which I can’t decide if regional or not: the inability to pronounce “st” at the beginning of certain words. I hear so many people say “shtraight” or “shtrength” or “shtrong”. We’ve got a local physical fitness guy on one of the TV affiliates in Detroit whose mangling of the “st” words is so pronounced, it’s difficult to listen to what he’s actually saying.
He and most others don’t seem to do it with all “st” words. I never hear “hey, shtay shtrong” or “Oops, I shtumbled”.
Why is that? Is it a regional thing?
Sean Connery’s a physical fitness guy? Good on him at his age.
