History Recap / FuturamaS6E10ThePrisonerOfBenda

''[[CouchGag What happens in Cygnus X-1 stays in Cygnus X-1]]''

* EnsembleCast: There's no central plot other than disorganized chaos around the rapidly switching bodies.

** Hermes, who is normally tubby, actually becomes thinner at the end of the episode while Amy was in his body, which was caused by her suddenly losing her appetite while at Elzar's. He is back to his normal self the next time he appears.

** Hermes, who is normally tubby, actually becomes thinner at the end of the episode while Amy was in his body, which was caused by her suddenly losing her appetite while eating a pork sundae at Elzar's. He is back to his normal self the next time he appears.

** Amy manages to get Leela's thin and attractive body, which she uses to angst to Hermes, who is also feels troubled with his body. Leela's body manages to get better at the end of the episode though.

-->'''Nikolai''': So long, filthy commoners!
-->'''Bender''': [[GratuitousSpanish ¡Adios!]] And I'm left with the real jewels safely inside... ''(Looks inside his chest cabinet.)'' [[OhCrap HIS COMPARTMENT?!]] AW! All right, [[HereWeGoAgain I'll need accomplices]].
* ShoutOut: In order to test Bender in Amy's body, Basil and Nikolai employ a ''reverse'' Turing Test, an inversion of the Turing Test, which is when a computer can pretend to be sufficiently human.

* ShownTheirWork: As mentioned before, this episode is notable for having episode writer Ken Keeler (the same one who wrote the infamous ''Simpsons'' episode "The Principal and the Pauper"[[note]]the one where Principal Skinner is revealed to be a street punk named Armin Tamzarian, while the real Seymour Skinner is a Vietnam War vet who was missing and presumed dead[[/note]]) create The ''Futurama'' theorem, a real-life mathematical theorem invented purely for use in this episode, proving that regardless of how many mind switches have been made, they can still all be restored to their original bodies using only two extra people, provided these two people have not had any mind switches prior.

* UnexplainedRecovery: Zoidberg in Fry's body & Nikolai in Wash Bucket's body ignite gas and blow it up in Fry's apartment, but in the next few scenes, they are shown uninjured and unaffected.

* HeroicSacrifice: Big Bertha fires Farnsworth in Bender's body so that it can reach the United Nations to save Bender in Nikolai's body, even though the blast will end up destroying her already battered body.

* NutritionalNightmare: One of the foods that Amy eats in Leela's body is a deep-fried ice cream sandwich wrapped in frosting and lightly baconed, which she proceeds to eat with ketchup.

* FreakyFridayFlip: Notable in that, while most "FreakyFridayFlip" plots use magic or don't explain why two or more people switch personalities (other than it being AnAesop about learning perspective and "walking a mile in someone else's shoes"), the the reason why two or more people are switching personalities is part of a criminal plot gone wrong rather than a "two different people argue over who has it tougher" plot.

* IgnoreTheFanservice: The reason Bender stole Amy's body was to utilise her body to seduce the guards. This fails the minute he encounters Basil, who as a robot obviously isn't going to be distracted by a human woman. Bender has to resort to punching him out.

* FreakyFridayFlip: Notable in that, while most "FreakyFridayFlip" plots use magic or don't explain why two or more people switch personalities (other than it being AnAesop about learning perspective and "walking a mile in someone else's shoes"), the episode writer (Ken Keeler) came up with a mathematical theory that makes this physically possible and the reason why two or more people are switching personalities is part of a criminal plot gone wrong rather than a "two different people argue over who has it tougher" plot.

* AnAesop: Be happy with who you are. Laid out by the robo-Hungarian cannon, who may be old and breaking down, but she prefers it to changing who she really is.
