Brick is JT's best friend, who wears his thick, black hair neatly and lives his life uncleanly. He's not that bright and often causes trouble for JT. Of course, his intentions are always good and his attitude is always positive, so Brick usually gets away with anything that he does. One of the most noticeable things about Brick is that his eyes will roll around, showing his lack of direction. Well, that and his love for Lamp the Lamp.
Music Video Stars
Characters who appear exclusively in JT's music videos. They add liveliness to the MVs...yet have no personality. They're not seen much in later episodes, but you'll occasionally see them in the background, filling up space.
