In Episode 11, "Tom's Divorce," the crew is trying to cheer up Tom, who just got divorced. They end up taking him to a strip club. Here's Leslie Knope's reaction right before they go in, and right after. The brilliant part of this scene is you don't have to be a feminist to find it funny (though it might help, who knows). And to preempt any shouts of "slut shaming," if you watch the full episode, and especially the full series, I don't think you'll find that to be the case.
Should that video clip not work, here is the dialogue, thanks to Knope Knows:
Leslie: Ciara, sorry it’s loud in here. And, um, I gave her money to writhe around on your parts.
Leslie (to Ciara): Go crazy, OK? Give my friend here the works. Really grind the sorrow out of him.
Tom: This isn’t working. I don’t want to do this.
Leslie: Is it because you have a strong positive female figure watching you?
