Former 'Saved by the Bell' stars reunited

Dennis Haskins is determined to stage a "Saved By the Bell" reunion any way he can.

Best known for his role as Principal Belding on the hit teen sitcom, which aired on NBC from 1989-93, Haskins told TMZ last month the timing is right for a "Saved By the Bell" comeback and fans deserve one. But he hasn't stopped there. Haskins, 62, crashed Tiffani Thiessen's Tuesday morning appearance on "Today," making the actress visibly uncomfortable.

Eventually, Thiessen, 39, relaxed during the mock game-show portion of her interview on "Today," but you could tell it wasn't easy. Haskins played host and quizzed Thiessen and anchors Al Roker, Natalie Morales and Willie Geist on sitcom trivia.

Perhaps Thiessen responded awkwardly because she's been avoiding a "Saved By the Bell" reunion for years. As fans know, Thiessen played Kelly Kapowski on the show. But Thiessen's reluctance isn't the only reunion roadblock.

Haskins later said on "Today," that "It's not like something is holding it up -– I think it's a matter of timing and finding something that everyone wants to do. There's some issues with Dustin (Diamond). He wrote a book that wasn't real positive."

"Today" airs weekdays at 7 a.m. ET/PT on NBC.
