Some of the characters and their costumes are from Earthland Realms, an online game in the Simpsons universe which parodies online MMORPGs.
Upon entering the maze area, Marge notices the camera switching to overhead POV (point-of-view). Homer states that this is just like his favorite old sword-and-sorcery game, Dig Dug - which is neither a sword-and-sorcery game nor even set in overhead POV, at least not until the sequel, Dig Dug II.

One of the lines said by the Comic Book Guy fire sumos is "Just a flesh would", a recycled line from Final Fantasy IX which is, in itself, a reference to the film Monty Python and the Holy Grail.

Homer can say that he has an urge to sit on a couch, or has an urge to send money to Danny Elfman, who composed the Simpsons theme.
Upon entering Matt's office, the Comic Book Guy points out the Evil Genius cliche as being "a rip-off of Lex Luthor," a constant adversary of Superman.
Matt introduces himself to the Simpsons by saying that "Your creator is TV's most beloved animation visionary!".
