Jimmy Fallon reunites (and joins) the cast of 'Saved by the Bell'

In the same week that Jimmy Fallon sang Brady-bunch style with the likes of Ariana Grande, Usher, and Carrie Underwood and hosted the most memorable lip-sync battle in Tonight Show history, he also joined the cast of Saved by the Bell.

Fallon brought back Zack Morris, A.C. Slater, Jessie Spano, and Kelly Kapowski—and then lived every ’90s kid’s television dream. In eight minutes of awesome Bayside nostalgia, Fallon and the gang relived some of the most classic Saved by the Bell moments.
