Jimmy Fallon always said he would reunite the cast of "Saved by the Bell" and he did just that Wednesday (Feb. 4) night. You have to see this hilarious video.

Fallon plays a younger version of himself as he enrolls in Bayside High School and joins the well-known resident students. Zack, Kelly, A.C., Jessie and Mr. Belding all make an appearance.

The Bayside students re-enact memorable moments from the series that you may remember from your Saturday morning routines. Jessie's "I'm So Excited" moment, Slater's ballet moves, and even Zack Attacks hit, "Friends Forever."

They even poke fun at Jessie becoming a stripper -- think of Elizabeth Berkley's role in "Showgirls."
