Kelsey Grammer and Joe Mantegna both play long-running recurring characters on The Simpsons (1989). Grammer plays Sideshow Bob, Bart's psychotic archenemy, and Mantegna plays resident Springfield mob boss Fat Tony. As an amusing in-joke to "Frasier", David Hyde Pierce and John Mahoney have also appeared on the show as Cecil and Bob Terwilliger, Sr. - Sideshow Bob's brother and father, respectively.
The music the mariachi band begins to play before Frasier and Derek Mann's fight is "Cielito Lindo," a traditional Mexican love song.
This is the first episode in which Frasier's name appears in the title.
Roz turns her nose up at dating a sanitation worker, yet ends up dating one in later episodes.
