TheAbbott ElementaryandIt’s Always Sunny In Philadelphiacrossover lived up to its hilarious hype, but the ABC mockumentary also added in some Easter eggs for fans of the FX sitcom. The crossover event hadAbbott Elementary’s wholesome cast of characterscrossing paths with the nefarious"Gang"fromIt’s Always Sunny In Philadelphia, characters that are irredeemable and proud.

In fact, theIt’s Always Sunny In PhiladelphiaandAbbott Elementarycrossovereven separated The Gang into“heroes”and villains. While the family of Dennis Reynolds (Glenn Howerton), Deandra“Dee”Reynolds (Kaitlin Olson), and Frank Reynolds (Danny DeVito) all had some sort of antagonism during the episode, Ronald"Mac"McDonald (Rob McElhenney) and Charlie Kelly (Charlie Day) ended up helping the Abbott crew solve their problem— through blackmail, of course. The Gang would never help someone above board. While the plot was entertaining,a few key references toIt’s Always Sunny In Philadelphiamay have flown under the radar on a first watch.
