According to the song "Robot Hell" there are at least 6 levels of hell, because after the 5th level, they took the elevator down once more. Also, Robot Hell is located in a New Jersey theme park.
Near the end of the "Robot Hell" musical,and while describing various tortures, the Robot Devil mentions electric slime. This really wouldn't work as a torture seeing as how Bender enjoys electricity.
When Fry and Leela enter "The Inferno" on the bottom wall you see a heart shape with the initials H. S. (Homer Simpson) plus M. B. (Marge Bouvier) inside it, which is a reference to Matt Groening's other show "The Simpsons".
The songs performed by The Beastie Boys are "Intergalactic" and an acappella version of "Sabotage." "Super Disco Breakin" can be heard during the mosh pit scene.
Opening theme promotion: CONDEMNED BY THE SPACE POPE.
LOOK HARD: Dan Castellanetta has his own head in a jar in this episode.
Robot Hell has an above ground entrance with a sign that says "The Inferno."
The episode title "Hell Is Other Robots" is also the name of the pamphlet that Beelzebot gives to Bender in Robot Hell.
Lady Luck's Array of Tortures: Parboil, Fricasee, Saute, Pleasant Massage, Deep-Fry, Bake.
The Robotology symbol is the resistor symbol from a circut diagram.
You can actually see a crate with the label "Replacement Robot Legs" beside the meeting table after Bender was unstuck from the ship.
The "Good Book" (ver. 3.0) is on a 3½-inch floppy disk. In the present, floppy disks are obsolete.
Fender who makes 20th century musical instruments and amplifiers are apparently still in business.
When the Planet Express people are talking to Bender about almost killing Fry and Leela, Fry isn't there in the room. A few seconds later, Fry has suddenly appeared to talk about how he found out his friend was taking drugs.
The guy who pushes the Beastie Boy's heads onto the stage is Scruffy, whom we also know as the Planet Express janitor.
When Fry, Bender and Leela are "assigned" to deliver a piece of wrapper to a mailbox, Leela takes Nibbler with her. A few second later, when Fry, Bender and Leela are in front of the robot strip joint, Nibbler is gone. Not even his leash is there!
When Bender was rolled into a cigar, the animators didn't account for his body. The width of Bender's body versus his head is larger. But when in the cigar paper, his body (in the paper) was the same width as his head.
Whenever Bender is putting his new religion sign on the space ship his isn't on him. In the next clip it appears again.
When Fry is outside waiting for Bender, the clock changes from 8.30 to 8.00.
The "Millennium" ticker is not there at first, and then suddenly appears.
Millennium is spelt wrong, with just one "n".
When Bender quit drinking in "I, Roommate," he developed a five O'clock rust, but here it has little effect on him.
EDIT: In "I, Roommate", Bender stopped drinking altogether, but in this episode, he had simply switched to mineral oil. Thus his alcohol level was maintained, just not in a 'sinful' way.
