The Abbott Elementary crossover airs as episode 409 of the series. Kaitlin Olson, of It's Always Sunny, said the following about the crossover and revealed the second episode during a recent appearance:

“It was very fun. And they’ll be jumping into our world in a couple of weeks, which is very exciting. So it’s been really fun for both of our casts to be able to do, them a cable show and us a network show.”

Patrick Schumacker, executive producer of Abbott Elementary, said the following about combining the series:

“It was kind of a joke at first, that the two shows should cross over. On paper, it feels like they’d be a real tonal mishmash. But then Rob and Charlie came to our writers room and we hashed out some real broad stroke ideas. From there, we emailed back and forth beat sheets and then an outline. They were super game for everything. All those concerns that we had about the tones of the shows butting against each other were alleviated the second we started filming with Charlie.”

Season four of Abbott Elementary airs Wednesday nights on ABC. It's Always Sunny in Philadelphia airs on FXX and has already been renewed for an 18th season. The start date of the 17th season has yet to be announced.
