With The Tonight Show taking up residency in Los Angeles this week, Jimmy Fallon took the opportunity to visit his old stomping grounds: Bayside High.

Fallon reunited (most of) the cast of Saved by the Bell - Mark-Paul Gosselaar, Mario Lopez, Elizabeth Berkley, Tiffani Thiessen and Dennis Haskins - in a perfect throwback that features Slater (Lopez) doing ballet in his famous black unitard, Jessie (Berkley) getting "so excited, so scared," and an amazing mullet wig on Fallon himself. (Absent were Lark Voorhies and Dustin Diamond, likely due to his recent legal woes.)

Our reaction:

Check out the skit below - in which Jimmy discusses his dreams of moving to New York to be on Saturday Night Live (and date Nicole Kidman), and Zack makes a reference to Jessie becoming a stripper. Plus: Zack Attack!
