From Dryer, Dryer’s English
“Two women are seated side-by-side at a posh dinner party, one a older frosty matron, the other an easygoing Southern gal.
Southern gal, amiably to Frosty Matron: So where y’all from?
Frosty Matron: I’m from a place where people don’t end a sentence with a preposition.
Southern gal, sweetly, after a moment’s hesitation: Ok. So where y’all from, bitch?
