Dennis Haskins: Then
As Bayside’s principal Richard Belding, Dennis Haskins appeared more than any other cast member in all of the various iterations of “Saved by the Bell,” and with him came his constant refrain: “Hey, hey, hey, hey, what is going on here?” Haskins’s adult presence was a reliable foil for the mostly teen cast, especially Zack Morris, whose antics both annoyed and impressed Belding to no end.
