Major spoilers below for the Season 17 finale of "It’s Always Sunny in Philadelphia," so be warned if you haven’t yet watched via Disney+ subscription or Hulu subscription!

As huge fans of this show for the past two decades, we thought we knew everything we could expect from any given episode, despite being blown away in the past by "Always Sunny’s" genre-bending finales. But we were properly schooled, and it didn’t even involve any "Abbott Elementary" teachers crossing over.
