A large number of relations in the show were never cast, and thus never appeared on-screen. For instance, Kelly has mentioned that she has six siblings, but we only ever meet one sister and one brother. Viewers never see Slater’s mom, Screech’s dad, Jesse’s mom, or Kelly’s mom. Zack’s parents are both seen but are never in the same scene.
The only exception to this is when they, along with Kelly’s parents, show up to watch the characters get married in Wedding in Las Vegas. We also never see any part of Zack’s house except his bedroom or living room, and we never even see the outside of the school.
Magic to The Max
One of the most famous sets in the show – and indeed in pop-culture – is “The Max,” the diner where the gang would hang out after school. Several of the characters got part-time jobs there, the vivid decorating style became a classic symbol of the late eighties and early nineties, and the owner Max loved his magic.
In fact, Ed Alonzo, who played Max, is a real stage magician and illusionist – he even helped create special illusions for Britney Spears and her 2009 “Circus” tour. While he never does anything too crazy for the show, he's always ready to show off. However, Max never appeared after the second season for what is being called “Proto #MeToo allegations.”
The Almighty Time-Out
Somehow, for some reason, Zack Morris has a superpower. Just by yelling “Time Out!” he can freeze time for everyone but himself. He would use this opportunity to speak directly to the audience, move people around, get out of sticky situations, and get into more mischief. It was an especially weird part of a show with plenty of it, though it was much more common in the earlier seasons.
Zack's ability to do this is never really explained in-universe, though some commentators have noted it makes Zack into an almost deific character, especially that of a trickster God such as Loki, due to his manipulation, but is unable to handle even a taste of power. Only once is a character not frozen when Zack yells Time Out: Screech, in the glee club episode of season two.
Brothers On-screen and Off
Principal Belding is an uncool, desperate character who can barely keep up with the kids when it comes to schemes, which is why it's such a shock for Belding's brother, Rod, to be a laid-back, cool substitute teacher. He only appeared in “The Fabulous Belding Boys,” which has the brothers butting heads about teaching style and life choices – Rod ends up missing an important field trip to spend the weekend with a stewardess.
The actor who played Rod, Edward Blatchford, is Dennis Haskins's brother in real life, though hopefully, their relationship is better in real life than the one they portrayed in the episode.
The Accolade
"Saved by the Bell" had astounding popularity. It became one of the biggest shows ever after only four years. It broke the Saturday-morning mold, ousted cartoons from the NBC lineup, had better ratings than The Cosby Show, the biggest sitcom of the time, and even the reruns were grabbing millions of people on the regular. It made millions, launched several of the young actors to fame, and is still cited as one of the biggest pop-culture icons of the early nineties.
Yet, for all that, it was nominated for only one Daytime Emmy: Outstanding Achievement in Lighting Direction. They were nominated for, and won, a number of smaller awards, but didn't even win the Emmy.
