|Colonel Sanders Junior sez it iz funnee|
It never occurred to me (until it was too late to change) that most folks don't associate the American South and Br'er Rabbit as automatically as I do. So, that's what the bunny is doing here, at least nominally. Also, I did Thor from memory, so any bits I got wrong are due to a not-intimate knowledge of the Jack Kirby designed outfit. And it's pretty assumed he's got a beard these days, I guess?
Final footnote: photographs of George William Bagby prove he dressed like Matlock. I swear, Google it.
