"The Jazz Hole" may be a reference to New York City jazz club "Birdland" which is in a basement, named for saxophonist Charlie Parker. It may also be a play on words; the archaic spelling for "jazz" is "jass" ("The Jass Hole").
The background noise of the arcade is the music from the Tetris arcade machine.

There is an internet Creepypasta that says that this episode code (7G06) was originally from another episode which is called "Dead Bart".
