Trivia: The searching for buried old video game cartridges is based on a true event of Atari burying their failed video game, "E.T." (arguably one of the worst video games ever and leading to the home video game crash). Atari secretly crushed and buried unsold cartridges, which also mistakenly became an urban legend where the idea of the massive burial was regarded only as a myth. In 2013, a company was granted access to the landfill "E.T." was buried in and a documentary was made filming the search and un-burial, also something one of the characters in the episode said he did.

Trivia: "The Hound of the Cancer Cells" is a loose reference to "The Hound of the Baskervilles", perhaps the most famous of the four Sherlock Holmes novels.
Chosen answer: M broke into the brownstone and left a note. Holmes deduced he was staying at a high-class hotel from the soap scent on the note, and gave a picture from a hidden camera to his "irregulars" on the street to stake out hotels. One of them saw him, so Holmes followed him to his next intended victim and knocked him unconscious with a baton.
