Profile: Bart Simpson
He is yellow. He is short. He has between seven and nine spikes on the top of his head. He is (at his worst) corrupt and evil; at his best mildly annoying (such as when he makes crank calls to Moe's Tavern and asks for Al Coholic or Mike Rotch). He appeals to kids (who want to be just like him) and adults (who know their kids already are just like him).
