The altercation between Gangstalicious and Eat Dirt was supposed to be a silly, childish fight but the animators drew it as a violent gunfight.
During the Gangstalicious documentary, a graffiti tag that says "SEUNG" can be seen in the background. This is a reference to Seung Eun Kim, director and producer on the show.
There are two references to Eddie Murphy's comedy. "I seent the the whole thing" is from his first, eponymous album, "Eddie Murphy". "My shoe!" is from his first stand-up special, "Delirious".
