When I was a very young child, this was my favorite thing on TV. And to my parents' horror, any time I saw a black man in public, I would get all excited and point at him and scream GENE GENE DANCING MACHINE!!! I'd always be disappointed when they didn't start dancing for me.
I like how his outfit for dancin' on national TV for a bunch of white people is the exact same thing he wears to the barbershop or to play chess in the park with his grandpa. (Yes, those are the actions that black men of his age and stature do regularly.) It makes this whole thing seem like something he does every day.
