Zack Morris! Kelly Kapowski! A.C. Slater! Jessie Spano! Mr. Belding! They're all here (okay, no Screech, because he's probably in jail). The Tonight Show with Jimmy Fallon spent eight whole minutes on a Saved By The Bell sketch featuring the original cast, almost 25 years after the NBC Saturday morning kid-com made its premiere. Everybody looks pretty good! Sadly, Jim Harbaugh couldn't make it.
