Donald Glover, who you may know as a former "30 Rock" writer and the best part of "Community," has a Comedy Central special this week. In this clip, Glover talks being a black nerd, which is something he's proud to be. But it wasn't until trailblazers like Obama and Kanye made nerdiness acceptable that he was so open about it. Not too long ago, the only reference point people had for black nerds was Urkel. But as Glover clarifies, Urkel was no nerd. "Urkel was retarded."
