The 2014 indie film Obvious Child begins with Jenny Slate’s character on stage, performing stand-up about her . . . cervical fluid. “I used to hide what my vagina did to my underpants, and by the way what all vaginas do to all underpants, OK? There is no woman who ends her day with, like, a clean pair of underpants that look like they’ve ever even come from the store. OK? They look like little bags that have fallen face down in a tub of cream cheese and then commando-crawled their way out and then caribiner-ed up into a crotch. They’re not items for anyone to see. Now I’m just like whateeeverrr. You know, I have a human vagina.”
