It was funny when he did it on the show but even then it seemed like it was funny because he was referencing an uptight, well to do, stereotype. Like "Black guys do it like this but white guys, they do it like THIS!" type of humor. I'm pretty sure he got the dance from some place else. When this is discounted, I hope he isn't smacked with a countersuit or court costs.
And again, that's IF y can somehow copyright a motion that the human body does.
