James "Toofer" Spurlock is a recurring, then regular character portrayed by Keith Powell on 30 Rock.
Toofer is an African-American writer for TGS.
He has an aversion to the stereotypical aspects of black culture that he believes are embodied by Tracy Jordan.
Therefore, his primary purpose on the show thus far seems to be as a foil to Tracy Jordan. And to get picked on by Frank as well.
Toofer: He's an imbecile.
Pete: Well, he's our imbecile now.
Tracy: So, how you doing over there, Theo Huxtable.
Toofer: I'm doing good.
Tracy: Nah-uh. Superman does good; you're doing well. You need to study your grammar, son.
Frank: [to Toofer] Wow, that was embarrassing for you.
