The highly anticipated crossover episode between Abbott Elementary and It's Always Sunny in Philadelphia is almost here and PEOPLE has the exclusive first look!

The episode, titled "Volunteers," airs Wednesday, Jan. 8 and fans will see Ava (Janelle James) announce that the school district is sending over a group of volunteers to help at Abbott. Despite the extra hands, when the volunteers arrive, things "don't go as planned," according to the episode's official log line.

"Welcome to Abbott Elementary, the best elementary school in the universe!" Janine (Quinta Brunson) says excitedly while making introductions.

"Is that what this is?" Deandra (Kaitlin Olson) asks, unimpressed by what she sees.

While it's clear the teachers and the volunteers will have their differences, some of them aren't afraid to mingle.

"Let me know if there's anything you need, and I mean anything," Mac (Rob McElhenney) teases after cornering an unenthusiastic Ava in the teacher's lounge.

Mac may have love on his mind, but Mr. Johnson (William Stanford Davis) and Frank have their fists up as they butt heads.

"You're trash you know that?" Mr. Johnson says as Frank defiantly replies, "Coming from the sheriff of trash!"

After months of teasing about a potential Abbott Elementary crossover, It's Always Sunny star and creator, McElhenney confirmed that the long-running series would be joining forces with the Emmy award-winning comedy about teachers for an episode.

In early October, McElhenney shared a photo featuring him posing with Charlie Day and Brunson in front of the iconic Abbott Elementary school and gave fans a sneak peek into what was coming on social media.

“Oh. Hello,” he captioned the post.
