Good Morning, Miss Bliss (https://en.wikipedia.org/wiki/Good_Morning,_Miss_Bliss), for those who don't know, was the prequel series for Saved by the Bell that aired on Disney Channel for a single season in 1988-89. It started Hayley Mills as the titular Miss Bliss and also featured Zack, Lisa, Screech, and even Mr. Belding in junior high school.

Like Season 1 of The Facts of Life (1979-80), GMMB had 13 episodes, was very different from the other seasons, not fondly remembered, but still left a lasting impact in a ironic way.
