Humans rejoice because class is back in session. That’s right, most of everyone’s favorite community college study group is back in the first official trailer for “Community” Season 6, coming to Yahoo TV.

The Dan Harmon-created show suffered a tumultuous relationship with NBC for five hard fought seasons before the network finally pulled the plug last year. Unable to squash fans demand for “six seasons and a movie,” the show was picked up as a Yahoo TV web exclusive. Since then, fans have been in the dark about what the change will mean for the students and faculty of the fictional Greendale Community College. Now, with the release of the trailer, fans are getting their first look at what the study group will be up to on their new Yahoo home.

The trailer, which is a parody of the recently released trailer for “Avengers: Age of Ultron,” opens by addressing the absence of Shirley (Yvette Nicole Brown), who became the third principle cast member to leave the show following Chevy Chase’s very public exit and Donald Glover’s decision to leave the show to pursue his music career. The actress respectfully stepped down from her role in order to spend more time with her sick father. Meanwhile, Jonathan Banks, who had a lengthy guest stint on Season 5, is not returning to the show in order to better serve the AMC series “Better Call Saul,” where he reprised his role as Mike Ehrmantraut from “Breaking Bad.”

To fill the gang’s respective slots, the trailer introduces Paget Brewster as Francesca ‘Frankie’ Dart and Keith David as Elroy Patashnik. The latter of the two has a hilarious moment where he tells the group that he won’t simply be there to assuage their white guilt, saying: “I’m no one’s fourth ‘Ghostbuster.’”

They new duo will join returning cast members Joel McHale, Alison Brie, Danny Pudi, Ken Jeong, Gillian Jacobs and Oscar winner Jim Rash for Season 6. Check out the trailer below to see the gang reunite for frisbee accidents, prisoner drones, giving degrees to a dog and more. Tune in to the Season 6 premiere on Yahoo TV Tuesday March 17.
