Futurama Episodes

The crew is out watching a game of blernsball when Bender notes that the robots are only employed as service workers to do the “crap work.” He grows increasingly upset by this, but his anger is interrupted by Hermes’ report of a package that arrived. The crew returns home and learns that the package’s destination is Chapek 9. Because the planet is inhabited by robots that kill humans on sight, only Bender can make the actual delivery. Unfortunately, the robots discover that he came with humans. Leela and Fry must go save him, even though he might not be as helpless as they think.
wikipedia.org summary:
The Planet Express crew deliver a package to Chapek 9, a planet inhabited entirely by human-hating robots who kill humans on sight. Bender is sent to deliver the package alone, but is captured upon discovery that he works for humans, so Fry and Leela disguise themselves as robots and infiltrate the robot society. When they find Bender, they discover that Bender has made himself an idol among the other robots out of frustration of feeling unappreciated by his crew. Fry and Leela are captured, but Bender refuses to kill his friends. They soon learn that the planet’s government is merely using humans as a scapegoat to distract the population from a valuable lug nut shortage. The three escape the planet and Bender, remembering he forgot to deliver the package, drops it onto the robots chasing them, revealing a shower of lug nuts and causing the robots to renounce their human-hating ways.
