She bugs me and I turn it off when one of her shows comes on. Most Southerners I know say "ya'll" but they say it casually, like it's a normal word for them to use. Paula Dean emphasizes it - YAWWWWWLLLLL - like she has a quota or something.
It's all part of her "act." It is annoying shtick. I bet if you actually talked to her away from her public persona, she wouldn't talk like that at all.
I also can't understand why people like her cooking. I saw her making burgers once, and they were big enough to feed five people, slathered in butter, and just greasy, disgusting, and gross. There is no way anyone in her family would have lived past 30 or weigh less than 500 lbs. if they really ate like she cooks.
That's why I like Alton Brown. You can tell when he's acting because he puts on a costume and uses silly props. He shows you how to cook real food, and teaches you things you can use in your every day cooking. He's the opposite of Paula Deen.
