KFC introduced their new Smoky Mountain BBQ flavor and a new colonel Sanders. They hired the one and only Reba McEntire. She's the first female to play the Colonel.
She sings about being the "real Colonel" and that you should "ignore any likeness to famous country singers." And then you see the real Reba in the crowd. It's all very tongue-in-cheek
The "real Colonel theme" started when they hired different people to play Colonel Sanders. Up to now it's been male comedians like Darrell Hammond, Norm MacDonald, Rob Riggle, and Jim Gaffigan.
