My mother was from north east Louisiana. My wife is from Tulsa, Oklahoma. Two of my kids were born Okies. What are you talking about southerners talking funny? Plumbers talk funny. They have a language all of their own and expect others to know it as well as they do.
Rich southerners actually have running water connected to the spiggot in the front yard. Rich southerners have two old cars setting up on blocks in the front yard--waiting for a Yankee car collector to come by and offer them $10,000 a piece for them.
I will have to say that one of my buddies from the Army (Forts Sill and Chaffee) dated a girl from over by Chickasha that told him "You sure do tawlk funnny." He had a cultured New York accent. She had the worst nasal twang you ever heard.
