Comedians Jeff Ross and Andrew Daly have booked guest star roles on the second half of the second season of TV Land’s ensemble comedy “Teachers,” Variety has learned exclusively.

Ross, who is best known as the Roastmaster General, will play a fire marshal who comes to Fillmore Elementary School after asbestos is found in Mrs. Adler’s (Kathryn Renée Thomas) trailer. And he will find himself in an extra comical situation when he walks in on Ms. Bennigan (Katie O’Brien) in the bathroom – more than once.

Daly will play a police officer visiting the school for an anti-drug presentation but ends up in an “opposites attract” scenario with Ms. Feldman (Cate Freedman). Daly was most recently seen on sister network Comedy Central’s “Review.”

Coming from improv group the Katydids who created the series, executive produce it and also star in it, “Teachers” tells the story of a group of elementary school teachers who are mold the minds of the youth by day but still struggle with getting their own lives together – also by day. The second half of season two will see Ms. Bennigan still naively pursuing Hot Dad (guest star Ryan Caltagirone), while Ms. Watson (Kate Lambert) is in an unexpected relationship and Mrs. Adler and Ms. Feldman are dealing with a “serial pooper” around the school. Meanwhile, Ms. Snap (Katy Colloton) finds the school’s forgotten library, and Ms. Cannon (Caitlin Barlow) discovers an artistic prodigy.

“Teachers” will also journey back to the 1940s for one special episode this season.

Alongside the Katydids, Alison Brie, Cap Gun Collective, Matt Miller, Jay Martel and Ian Roberts also serve as executive producers. “Teachers” has already been renewed for a 20-episode third season, which will premiere in 2018.

Variety also has an exclusive first look at the new season key art and promo for “Teachers”:
