Planet Express is going bankrupt again, so to raise money they convert their delivery company into an airline service. Some "difficulties" between the males and females result in a crash landing on a planet with a mineral-based life form, who uses them for test subjects of its studies, including playing hob with their genders.
Tropes
- Alien Gender Confusion: The mineral alien, having no concept of gender, tries to restore the now-sexless characters to their previous conditions, it gets them mixed up and makes the male characters female and vice versa.
- Attractive Bent-Gender: Fry during his bikini shoot. The Professor... not so much.
- Bowdlerization: In American syndicated television airings, the photo shoot of the Female Professor was censored by placing the fan in front of her.
- Brick Joke: Midway through, Fry hits his groin on a stalagmite but it doesn't hurt. He checks and immediately notices the problem. His groin area is gone. Later, when the rock alien restores the wrong sexes, Male Leela hits his groin on the stalagmite. At the end, when everyone's original genitals are restored, Fry tries riding a bicycle and hits his groin again, this time with the proper effect.
- Butterface: Zapp finds almost all of Female Fry attractive.Zapp: Well, hello from the neck down!
- Charity Workplace Calendar: In order to keep Planet Express afloat the Professor decides to put out a "Girls of Planet Express' calendar to raise money. The female employees aren't interested and are offended, but after an alien switches the Planet Express male and female sexes the now female (formerly male) Planet Express employees enthusiastically put together the calendar.
- Compressed Vice: At the beginning of the episode, every male Planet Express employee is suddenly misogynistic, and all the female employees suddenly act like stereotypical women for no reason other than to force the plot.
- Continuity Nod: Female Bender looks like Coilette, from "Bend Her".
- Explain, Explain... Oh, Crap!:Male Leela: Planet Express is still facing foreclosure, there's no way we can raise enough money to save this company.
Male Amy: Wait, what about the girly calendar?
Female Fry: Well, that won't work, remember? We only have three women on staff—(gasp) - Fanservice: Most of the first calendar shoot with Amy, Leela and LaBarbara (Hermes's wife). Particularly when Leela is wearing nothing on her upper body except suspenders.
- Fanservice Car Wash: The women of Planet Express — Leela, Amy, and LaBarbara (hired solely for this purpose) — are recruited to pose for a Charity Workplace Calendar. One of the last scenes of the sequence has them washing the ship in bikinis but in reality, that's just how they normally wash the ship.
- Fan Disservice: The second part of the Girly Calendar with the men-turned-woman starts out nice (Female Fry), but rapidly becomes very disturbing (Female Professor).
- Feet-First Introduction: The first we see of the Professor is his slippers... well his slipper walking aid.
- First Law of Gender Bending: Appears to occur to Scruffy, as he is in the bathroom when everybody else is returned to their normal gender. However, this is actually subverted, as in the next episode "Benderama", Scruffy is seen returned to normal.
- Gender Bender: The alien swaps sexes of the entire Planet Express crew. Leela and Amy do not enjoy being male, while Fry, Bender, and the other men-turned-women find the experience fun. And in a Call-Back, Bender's female form is Coilette.
- Girls vs. Boys Plot: The characters end up stranded on a barren, hot, rocky planet, and bicker relentlessly about which gender was responsible for the crash. A local rock-alien notes that, due to the gender divide, there clearly must be a superior gender, and makes them compete for the title...with the losing team dying in the heat. They all struggle, until it turns out that this was a test to try and teach them about cooperation. Because they failed, they simply get their genders removed, instead.
- Instantly Proven Wrong: After Leela and Amy complain about their now male lifestyles, they guess that men-as-women are having an even harder time getting used to their changed genders, right before they all return from having a wonderful experience.
- Larynx Dissonance: All of the gender-swapped characters keep their original genders' voices.
- Mars and Venus Gender Contrast: The episode exaggerates the differences between men and women for comedic purposes, before introducing a Sufficiently Advanced Alien who creates harmony by making everyone gender-neutral. Everyone's fine with it until they realize it means no sex, at which point they demand their genders back — only the alien gets a few things wrong.
- Mr. Fanservice: Leela, Amy and LaBarbara look very attractive as men (particularly LaBarbara).
- Never Trust a Trailer: The commercials for "Neutopia" made it appear that the cast being genderbent would be the main focus of the episode—in reality, said genderbending doesn't even happen until the last five(ish) minutes of the episode and most of the jokes during that time were already shown in the commercials.
- No Biological Sex: The rock-alien turns everyone gender-neutral, which boils down to removing their genitals (and, in the case of females, breasts).
- No Celebrities Were Harmed: The Borax Kid is a mineral version of Clark Gable as Rhett Butler in Gone with the Wind.
- Sexy Stewardess: Leela, Amy and LaBarbarba (Hermes' wife) become this when the Planet Express ship is changed into a commercial airline.Leela: There. It was hard work, but it beats posing in demeaning, skimpy modelling outfits.
Professor Farnsworth: Ladies, here are your demeaning, skimpy stewardess outfits. - Shown Their Work: When everyone's neutered, some of them exclaim about losing their sexual body parts—Zoidberg yells, "My gonopores!" Everyone looks at him with confused expressions, so he tells them to look it up. To put it as simply as possible, "gonopores" are the crustacean-equivalent to genitalia.
- Testes Test: Done twice. First everyone checks up on themselves when their genitals are gone and again later when they are restored.
- Tertiary Sexual Characteristics: When everyone switches genders, Zoidberg looks like how he normally does, only with eyelashes.
