Schoolly D is an American rapper that performs the Aqua Teen Hunger Force theme song that is used during the first seven seasons. He was, at one point, somewhat of a narrator for Aqua Teen Hunger Force; though, all he would do is say something unimportant such as the ridiculousness of bringing a mummy to a mall. These narrations would be used less and less as the series progressed, though they would be used more during Season 7. In Aqua Unit Patrol Squad 1, George Lowe somewhat replaced him as a narrator by reading the episode titles.
He also did the theme song for Aqua Something You Know Whatever, alongside another band. In addition, he makes a cameo in the Aqua TV Show Show episode "Muscles," offering to do Shake's brain transplant idea.
