I know, I know this makes me an unbearable pedant, but that is one fucked up looking piece of chicken right there.
I mean, I guess he's selling chicken in that it's a commercial for KFC... But it seems like the whole idea of the commercial is that he's talking about change, and the fact that you can get a fish sandwich at KFC is so monumental that it crushes his entire ideological platform (don't worry; he's okay, and he loves the sandwich).
I like to think that the concept of fried chicken as a stereotype was perpetuated by a concerned young doctor or nurse trying to address heart health and obesity in the African-American community.
