Matt Stone and Trey Parker brought the battle between men and women to the forefront of South Park last night—or more importantly, the battle between farts and queefs.

The particularly brilliant episode of the show’s 13th season began with the boys discovering that Terrence and Phillip, the beloved farting Canadian television duo that have had a hold on South Park Elementary since season one, have been replaced. By girls. To make matters worse, the Queef Sisters, their replacements on the Canada Network, are “two Canadian girls who love shooting air out of their vaginas!”

Needless to say, the boys are disgusted. And in true Matt and Trey style, the split between the boys and girls at South Park Elementary quickly escalates into a divide between all the men and women of the town—and eventually to Congress. The repeated question–What makes queefing worse than farting?—is put to the senate. And so, because it’s something only women can do, queefing is banned in America.

Seriously. Brilliant. What could gross out a man more than a bodily function they’re not able to perform?

Randy, Stan’s father, rubs it in his wife Shannon’s face with a victor’s glee—just before she shoots him down.

"This isn’t about queefing, says Shannon. “This has been about women having a little bit of fun at your expense. For just this one time, we could be the immature ones to make you feel uncomfortable. But no, you just couldn’t let us have that one little thing, could you? Because even though things are getting better for women, you still think of us as lesser people sometimes, and we always have to prove ourselves twice as hard. Congratulations, guys, for getting your way. Again."

And that’s all the debate over queefing and farting actually came down to—a ridiculous metaphor for what men can get away with, and women can’t. Using crude humor, South Park got to the same issue that we’ve been trying to tackle for so long: Feminism will never be fully realized until we all hold each other to the same standards. Here’s to day when all our gasses can be passed, in harmony.
