In my world, deep frying a turkey is not a passing fad. It's a highly effective and quick method of cooking a delicious whole turkey. A method which very likely has deep and long roots in southern cooking. That sounds pretty darned American to me, and since Thanksgiving is a uniquely American holiday, well.
It's also dangerous, as it can burn you and your shit up in the blink of an eye. Which is why I'm including this very official disclaimer: don't try this at home, especially if you're drunk or stupid or, God forbid, both.
