Mr. Dicenzo is a mafia boss that makes his first and only appearance in the episode, "Working Stiffs." In the aforementioned episode, Carl hires Shake and Meatwad to assassinate the boss while eating at an Italian restaurant. Though, due to the ignorance of Shake and Meatwad, the duo uses a caulk gun and a tangerine dart gun in order to kill him. Obviously, the stupidity of Meatwad ultimately makes the attempt backfire, and is then captured by Dicenzo and his goons. After being driven back to the Aqua Teen's residence, Meatwad ensures that Carl is "the guy" that set up and planned the entire assassination attempt. After realizing this, the mafia gang rapidly fire bullets into Carl's house, destroying his home and most likely killing him in the process.
