  • Janus is a Roman god generally depicted with two faces on the front and back of his head. Although he's considered the god of beginnings and endings, in this case it's also a reference to Dr. Janus having multiple "faces" (personalities).
  • When Butters is burning his other identities, he says "No more porn star Butters" this may mean he had underage sex, or just likes pretending to have sex.
  • Eric Cartman, Stan Marsh, Kenny McCormick and Kyle Broflovski have no speaking lines in this episode, they only appear once in the audience when Tuong Lu Kim and the Japanese man are talking about Asian diversity. As Kenny did not appear in the previous episode also, this marks the second episode in a row where Kenny doesn't do or say anything this season.
  • Inspector Butters is a reference to the episode "Butters' Very Own Episode", where Butters follows his father around for his mother as an 'Inspector'.
  • The word 'shit' is once again uncensored.
  • Butters mentions Professor Chaos, his dark alter ego from "Professor Chaos", and other past episodes. However how he mentions him suggests he now only sees Chaos as a play character rather than his desire for revenge.
  • City Wok is not the only Chinese restaurant in South Park. There is also a P.F. Chang's.
  • A running gag throughout the episode is the other characters unable to see a difference between Chinese and Japanese people, as they always refer City Sushi as a Chinese restaurant and from the "increased Chinese culture" they name the area Little Tokyo, which is Japanese.
  • Dr. Janus has at least eight split personalities not including himself; The Old Man, Billy, The Evil Psychotic One, The Con Artist, Sexy One, The Pizza Man, The One Who Sings, and Lu Kim.
  • It is the first episode to air in June since 2002 episode "The Simpsons Already Did It".
  • Tuong mentions that Japan has the highest suicide rate. Japan has been in the top 10 consistently since the 1990s recession.
  • At the Asian Diversity Day event, City Sushi has a sign outside showing their lunch specials, consisting of Beef Teriyaki, Chicken Teriyaki, Shirmp Stir Fry, Tempura Udon and Orange Chicken, all with a soda for $4.99 or $5.99 for Chicken Teriyaki.

References to Popular Culture

  • Butters Stotch references a line from the song "Convoy" by C.W. McCall while playing "Big Rig Butters".
  • When Butters films himself, it is a parody of Paranormal Activity, proven when Butters says, "This is like Paranormal."
  • The arrest of Dr. Janus references the final scene in Alfred Hitchcock's movie Psycho with him saying he, "would not even harm a fly".
  • When Dr. Janus is riding a tricycle, frightening Butters and calling himself Billy, This is a reference to the SAW movies.
  • LMFAO's "Party Rock Anthem" as well as the video are parodied during the intro of the Asian Diversity Awareness school assembly with Junichi Takiyama and Tuong Lu Kim.
  • In the scene where Dr. Janus says he's been scamming the town for 7 years, his computer's logo says "Bell". This could be a reference to real life computer company Dell. This has also appeared in other episodes, like "T.M.I.".
  • Dr. Janus' personality-jumping meltdown, complete with removal of hairpiece, is likely a reference to the film "The Stepfather", where actor Terry O'Quinn played a man who swapped identities frequently (and eventually involuntarily), sometimes removing his hair piece to distinguish.
  • When Janus stated that MPD isn't real, this refers to a dispute among psychiatrists. Some believe that MPD does not exist, and others believe it is only caused by therapy for other disorders.
  • When Dr. Janus has his first meltdown he finishes by saying, "The horned toad says we should go to Mexico." This is a direct quote from Lone Watie a Native-American character in the 1976 Clint Eastwood film, "The Outlaw Josey Wales".
  • The portrait on the wall of the staircase during the chase scene is "Self-Portrait By John Everett Millais".


  • Butters previously underwent psychiatric evaluation in "The Death of Eric Cartman", when his parents thought he was hallucinating and seeing a ghost.
  • The Stotches immediately dismiss their son's "trouble making" as not because of their parenting, claiming "they're awesome". Once again playing on the fact they are completely oblivious to how cold and harsh they treat him.
  • Once again Butters is blamed entirely for something he has practically little involvement in, and is grounded.
  • Inspector Butters is from "Butters' Very Own Episode".
  • The Japanese man, Junichi Takiyama, is from "HUMANCENTiPAD".
  • When Butters is running up the stairs of Dr. Janus' house, Dr. Janus says, "You can't run forever!" This line was said by Billy Thompson in "Insheeption" directed towards Mr. Mackey as a kid. One of Janus' personalities is called Billy, but the personality is a good guy.
  • Bradley Biggle can be seen in the crowd at assembly, implying that he has returned since his last appearance, which was in "Coon vs. Coon & Friends".
  • While burning away his stuff that makes him into whatever he believes to be, Butters was about to burn away his Professor Chaos costume until Dr. Janus intervened. Professor Chaos recently returned in the season 16 episode, "Butterballs".
  • In "HUMANCENTiPAD", Junichi Takiyama states he cannot read English. However, in this episode, he reads a letter from Lu Kim. It is possible, however, that he may have finally learned how to read English since the events of that episode. Implying, he might have attended a community English class.


  • When Mr Mackey is addressing the school at the Asian Diversity assembly, many children can be seen twice or more in the crowd, as well as some alternate versions of characters. This includes Tommy Turner, Bill Allen, Sally Turner and some unnamed characters.
  • After Butters had been diagnosed with Multiple Personality Disorder Linda and Stephen find their son pretending to be a truck driver in their backyard. Butters' gear shifter was positioned on his left-hand side, which is an error unless he was pretending to be a foreign (Japanese, British, etc.) driver.
