There's an episode of It's Always Sunny In Philadelphia that basically predicted the invention of Peeple, the new people-rating app that lets you score your friends and family from one to five. People (as in humans) have had a pretty skeptical reaction to Peeple (as in the app), noting that it could easily facilitate harassment, manipulation, and not feeling yourself. For a glimpse at what that frantic world might look like, we can now view this YouTube compilation of scenes from an It's Always Sunny episode when Dennis loses his mind over how women are rating him (out of five!) on a dating app called Buncher. His anxiety builds and builds until he runs around screaming at women that he's going to rate them all zero.
