Futurama: “The Butterjunk Effect” (7.6)

Futurama episodes don’t need to be completely out there and based on absurd science-fiction to be good… but it certainly helps. Partially it’s because after 120 episodes, the show has really covered a lot of the more mainstream sci-fi concepts. Plus, it being a Matt Groening show, it also has resistance to change, so that there are diminishing returns on episodes based upon character relationships—there’s only so many times that episodes based upon Fry courting Leela really work before it gets tiresome. “The Butterjunk Effect” doesn’t have those problems because it’s so different from pretty much everything, let alone previous episodes. While its sports-based plot is just vaguely reminiscent of the time Bender became a woman to cheat in the Olympics, otherwise it’s unique and strange and wonderful.
Following a shipment to moon, the Planet Express crew ends up watching an utterly ridiculous and violent sport, where two-women teams attach butterfly wings to themselves and beat each other up. For no particularly good reason whatsoever, Leela and Amy join the league and after being repeatedly walloped, start taking performance-enhancing nectar to improve their flapping muscles. It’s not until later, when they go to Kiff’s planet to harvest more nectar and Fry becomes an actual alien butterfly, though, when things really head off into unknown territory.
