Season 17, Episode 1 of FX's "It's Always Sunny in Philadelphia," marks part two of its crossover event with ABC's "Abbott Elementary."

When the narcissistic gang from "It’s Always Sunny in Philadelphia" visited the "Abbott Elementary" school in a crossover episode earlier this year, audiences got to see the two Philly TV universes collide in hilarious ways — all while keeping the episode PG for "Abbott’s" more family-oriented viewers.

It should come as no surprise to 'Sunny' fans that the gang gets more out of 'Abbott Elementary' than 'Abbott' gets out of the gang.
