Trivia: At the beginning of the episode, when Fry walks into the room wearing an orange space suit, you can see that Amy is busy reading a book (so busy she doesn't mind the odd liquid inside Zoidberg's bathtub being splattered all over her). The book's title is "Martians are from Mars, Venutians are from Venus."
Trivia: While at Luna Park, Bender throws a beer bottle and it sticks in the moon-head creature's eye. This is a reference to the image of the man in the moon with a bullet in his eye, from the 1902 French film, A Trip to the Moon (considered to be the first sci-fi movie).
Trivia: When Bender and Fry are with the Robot-Devil and he spins the wheel to decide whose hands he'll give to Fry, each and every name that appears on the wheel (freeze frame to see them all) are robots that have actually appeared in the series at one point or another. Verified on the DVD commentary.
Trivia: As the crew look at Blernsball displays, they come to races that broke the color barrier. The uniform and cap on the second one has the Star Trek logos on them, and the fourth is a native of the planet Sharron (Seen in the Star Trek episode "Let That Be Your Last Battleground").
Trivia: In the beginning, Bender and Fry are watching an episode of "The Scary Door", based on The Twilight Zone. In it, a man is billed as "The Last Man On Earth", and he is walking into a library. This is a mirror of the episode "Time Enough At Last", where the man is the survivor of a bombing holocaust, and winds up at a public library, saying there was time at last to read.
Trivia: There is an outside shot of the Planet Express at the start of the scene where they meet Dan McMasters. During this shot, a truck is visible driving with arcade cabinets attached to the back. One of the cabinets shows the Fix-It Felix, Jr. game from the movie Wreck-It Ralph.
Trivia: When the main characters are watching Fry through the two-way mirror, Hermes is eating popcorn out of a jai alai scoop. This is explained in a deleted scene, where Hermes says someone is stealing silverware from the kitchen so everyone has to use the scoops. The missing silverware is also explained in a deleted scene, where it's explained that the parasites are forcing Fry to eat silverware because they need metal for their city. When the group goes inside Fry to get rid of the parasites, you can see the top of a butter knife as part of one of the buildings.
