To help liven up stay-at-home guidelines, the Antenna TV network is offering up another pair of weekend marathons, this one designed to bring you back to the classroom with two of television’s funniest high school-set sitcoms, Howard Hessman‘s Head of the Class and Gabe Kaplan‘s Welcome Back, Kotter. Between April 11 and 12, fans can enjoy a total of 48 episodes of these shows.

Head of the Class originally ran on ABC from 1986 to 1991. Fresh off of WKRP in CincinnatiHoward Hessman is history teacher Charlie Moore, who takes center stage among a cast of younger co-stars as his academically-gifted students (consider it the opposite of something like Welcome Back, Kotter), including Robin GivensAlan Pinkard and Dan Schneiderthe latter of whom would go on to a highly-successful career as a writer/director/producer for Nickelodeon. In the show’s final season, Howard left and was replaced by comedian Billy Connolly.

Welcome Back Kotter, also an ABC show originally, ran from 1975 to 1979. The premise of the show — which introduced John Travolta to the world — has Gabe Kaplan playing Gabe Kotter, a teacher with a sense of humor who takes a job at his alma mater, James Buchanan High School, located in Brooklyn, New York. He’s given a classroom of juvenile delinquents known as the Sweathogs, and assigned by school assistant principal Michael Woodman to keep them “contained” until they either drop out or somehow manage to graduate. Instead, Kotter, who was one of the original Sweathogs in his youth, tries to connect with them to make them better people in the process.
