The Celebrity: R. Kelly as himself
The Appearance: “The Trial of R. Kelly” (Season 1, Episode 2)
The Reason It Worked: Because despite the fact that the Pied Piper of R&B doesn’t actually say much during the episode (um, you didn’t think these were all authorized appearances, did you?), the episode captures the mystique behind the guy in the mask. As Huey says during a scene that shows Kells singing and dancing on a courtroom table: “Don’t pretend the man is a hero!”
The Celebrity: Ghostface Killah as the Ghost of Ghostface Killah
The Appearance: “Stinkmeaner Strikes Back” (Season 2, Episode 19)
The Reason It Worked: Because, even as a ghost, Ghost stays fly—and says some pretty ridiculous things that only sorta make any sense to the sober folks watching at home.
