It’s time for a big class reunion. Twenty five years ago today, Head of the Class aired its final episode on ABC.

Created by Michael Elias and Rich Eustis, the sitcom centers on history teacher Charlie Moore (Howard Hesseman) and his group of gifted students at a Manhattan high school. William G. Schilling played the principal, Jeannetta Arnette was his administrative assistant and Charlie’s students were played by Leslie Bega, Dan Frischman, , Robin Givens, Khrystyne Haje, Jory Husain, Tony O’Dell, Brian Robbins, Kimberly Russell, Dan Schneider, Tannis Vallely, Michael DeLorenzo, Lara Piper, Rain Pryor, Jonathan Ke Quan, and De’voreaux White. Billy Connolly joined the cast in season five after Hesseman left the series.

The multi-cam comedy debuted in 1986 and ran for five seasons before ending on June 25th, 1991. Connolly reprised his role in the short-lived spin-off series Billy, which ran for half a season in 1992.

It’s worth noting that Robbins and Schneider went on to be very successful television show producers.
