‘Abbott Elementary’ and ‘It’s Always Sunny’ Crossover Episode Premieres January 8

The two Philadelphia-based comedies unite for a chaotic and unconventional collaboration that blends their distinct tones.

The crossover episode, titled 'Volunteers,' features the It's Always Sunny gang volunteering at Abbott Elementary, with hilariously disastrous results.
The episode was developed collaboratively by creators Quinta Brunson and Rob McElhenney, who saw potential in combining the two Philly-based shows.
Key moments teased in the trailer include Mac awkwardly flirting with Principal Ava, Frank and Mr. Johnson trading insults, and Dennis causing property damage in the gym.
Charlie Day's character is expected to play a significant role in the storyline, with hints of interactions addressing his literacy struggles.
The episode airs on ABC on January 8, 2025, at 8:30 p.m. ET, with a follow-up episode bringing the Abbott Elementary cast into the Sunny universe later in the year.
