We all watched 'Saved By The Bell'. It ran from 1989 to 1993. Jimmy Fallon reunited the cast for an 8 min skit on the Tonight Show.Zack Morris, Kelly Kapowski, A.C. Slater, Jessie Spano, Samuel "Screech" Powers and  Lisa Turtle were the kids of Bayside High, led by Principal Richard Belding.

Just a few of the characters made the skit. Apparently 'Screech' couldn't make it. Jimmy Fallon plays himself as the 'New Friend'.
