Cultural references

  • This episode is a homage to the Sherlock Holmes stories written by Sir Arthur Conan Doyle in the late 19th Century.
    • Baker Street is a real street in London; Sherlock resided there in the novels.
    • Mr. Lestrade is named after Inspector Lestrade.
    • Iggy & Ziggy Moriarty named after Sherlock Holmes's main rival Professor Moriarty.
    • Mr. Stapleton is named after Jack & Beryl Stapleton in The Hound of the Baskervilles.
    • Ms. Adler is named after Irene Adler, who appears in A Scandal in Bohemia, and has since became a love interest in subsequent adaptations of that story and other Sherlock Holmes stories in general.
    • A carbuncle is an old word for "gemstone"; the Blue Carbuncle is reference to The Adventure of The Blue Carbuncle, one of Doyle's short stories that featured Sherlock Holmes. While the mystery wasn't really "unsolved", Holmes refused to turn the culprit into the police which means it would have been officially recorded as such.
    • The Great Detectives Club is a reference to the Diogenes Club. The Diogenes Club was a club ran by Holmes's brother, Mycroft, in which members were forbidden from speaking.
  • There is a member at the Detective Club who resembles the TV detective, Kojak, who also likes lollipops.

Animation mistakes and/or technical glitches

Inconsistencies/continuity errors and/or goofs/oddities

  • Even though Holmes is supposed to be real here, it doesn't seem any of the competitors are descendants from those they allude to.
