Bender goes on a tirade about humans' mistreating robots, not helped by the latest mission: Delivering a box of lug nuts to a planet controlled by radical robot seperatists. Since the robots hate humans, Bender has to be the one to make the delivery. However, things quickly go awry once he's on the planet's surface, and now Fry and Leela must infiltrate a city of robots.

Though it might just be from that stupid movie.

- Distracted by the Sexy: When human hunting, Bender gets completely sidetracked by an old porno shop.

Leela: Of course.
- The Fourth Wall Will Not Protect You: At the end of the robot movie, a character warns that humans could be lurking anywhere... including movie theaters!Fry: God help us!

- Only Flesh Is Safe: Parodied with this line from a robot in a Show Within a Show: "Incredible. The human was impervious to our most powerful magnetic field, yet he was destroyed by a harmless pointed stick."
- Paper-Thin Disguise: Fry and Leela spend part of the episode rather poorly disguised as robots, but for the most part they get away with it.
- Poor Communication Kills: While Bender is sent to Chapek-9, he got so caught up with his "kill all humans" shtick that he forgot to deliver the package, a fact which is brought up as he, Fry and Leela are climbing to their ship to escape.

Fry: Well, aren't they?
Bender: I've never made anyone's life easier, and you know it!
- The Scapegoat / Demonization: Humans are given this treatment. The Robot Elders use the threat and hatred of humans to distract the robots of Chapek-9 from their real problems, like the crippling lugnut shortage, and a government of corrupt, incompetent Robot Elders.
- Shaped Like Itself: The prosecution at Fry and Leela's trial declares Fry and Leela, as humans "are guilty of the crime of being humans", before anounncing he rests his case.
- The first robot to realize Fry and Leela aren't robots roars a la Invasion of the Body Snatchers (1978).

- Sure, Let's Go with That: When Bender is describing humans to the other robots.
- Sustained Misunderstanding: Fry thinks Chapek-9 is uninhabited, even after Bender points out it's inhabited by robots. Fry assumes this is like how a warehouse is inhabited by boxes.

[Fry and Leela whisper about their options.]
Fry: Is the puppy mechanical in any way?
Guard 1: No! It is the bad kind of puppy!
Leela: Then we'll go with that data file.
Guard 1: Correct.
Guard 2: The flower would have also been acceptable.
- Urine Trouble: While disguised as a robot in Chapek-9, Fry has to pee and goes in a corner. A robot passes by and thinks Fry is leaking coolant. It takes several seconds (and even more false tries) before Fry's "leak" solves itself.
