Mark-Paul Gosselaar, Mario Lopez, Elizabeth Berkley and Tiffani Thiessen reprised their AMAZING roles from the 1990s sitcom for a brand new sketch.
Yep, Zach, Slater, Jessie and Kelly were BACK!
Mr Belding (Dennis Haskins) even joined in the fun!
The reunion was staged on The Tonight Show with Jimmy Fallon in a sketch imagining what life would be like if Jimmy had gone to Bayside High.
Oh, and if Zach had got Kelly Kapowski pregnant!
Everything about the sketch was perfect: the same school hallway, same red lockers, giant mobile phones, colourful clothing, not to mention Zach's perfectly coiffed blonde hair.
Ah, the memories!
There were also plenty of references to things the cast have done since Bayside High.. including jokes about Elizabeth Berkley's role as a stripper in Striptease and Tiffani Thiessen joining Beverly Hills, 90210.
Saved By The Bell aired between 1989 and 1993 and then spawned two spinoff series called The College Years and The New Class.
There were also two movies: Hawaiian Style and Wedding In Las Vegas, the latter giving Zach and Kelly their happy ever after.
