If you can believe it, "Saved by the Bell" is 30 YEARS OLD. And that had TIFFANI THIESSEN and MARIO LOPEZ feeling old on "The Ellen DeGeneres Show" yesterday.
They even have KIDS who are old enough to watch it. Kind of. Tiffani said she let her 8-year-old daughter watch the first season . . . but cut her off when, quote, "kissing started happening."
But Harper wanted to keep going, because she's already BOY-CRAZY, and she was totally into Mario and MARK-PAUL GOSSELAAR.
Mario's kids had a different reaction . . . quote, "My kids have given it a shot . . . not feelin' it. [They're like], 'Daddy why is your hair like that?'"
