Homer's Phobia
Brother from Another Series
My Sister, My Sitter


  • Sideshow Bob is voiced by Kelsey Grammer, who played Frasier Crane in the TV sitcom Frasier, which was still on the air when this episode first aired. His brother, Cecil Terwilliger, is voiced by David Hyde Pierce, who played Frasier's brother Niles in the show, hence the episode's title.
    • The title is also a reference to the film Brother from Another Planet.
    • When Bart covers Cecil's eyes and asks "Guess who?", Cecil guesses "Maris". Maris was Niles' unseen wife in Frasier.
  • Krusty's prison concert is a reference to Johnny Cash's famous At Folsom Prison concert and album.
  • At one point in the episode (just before Bob and Cecil discuss wine at his apartment), a parody of one of the title cards from Frasier is shown.


  • Bart was aware about Bob trying to murder him, but he already understood it in Cape Feare.
