Mr. Belding always did want to be part of the cool crowd.

A "Saved By The Bell" reunion took place on NBC's "Today" show on February 5 when Dennis Haskins, who played the high school principal on the 1990s show, showed up in a middle of a segment featuring guest co-host Tiffani Thiessen, who played popular girl Kelly Kopowski.

Haskins replaced weather anchor Al Roker as the host of a mock game show set in a replica of the school series' flagship eatery The Max to quiz him, Thiessen and co-anchors Natalie Morales and Willie Geist about 1980s and 1990s TV trivia.

"Hey, hey hey hey hey ? what's going on here?!" Haskins said as he entered the set.

Thiessen, who currently stars on the USA show "White Collar," did not show much enthusiasm and did not volunteer to answer a question about her role on another series, "Beverly Hills, 90210," in which she played the conniving Valerie. Morales shared a buzzer with Thiessen and joked that it was dysfunctional after the men shouted the correct answer.

However, the two were later seen smiling as they posed for a group photo, which Haskins posted on his Twitter page.

Haskins, whose Twitter username is @mrbelding, has in recent years made guest appearances on shows such as "How I Met Your Mother," "Men of a Certain Age" and "Mad Men."

The actor has talked about having a "Saved By The Bell" reunion before with all members of the cast. He told "Today": "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."

Haskins added that he does not harbor any ill feelings towards Diamond, who played Screech, a kind-hearted but annoying geek who is best friends with main character Zack Morris, who was portrayed by Mark-Paul Gosselaar.

In 2009, Diamond released a tell-all book called "Behind The Bell" in which he made disparaging remarks about his co-stars, including Thiessen, Gosselaar and Mario Lopez, with regard to their sex lives. That year, People magazine featured a photo shoot with the main cast members of "Saved By The Bell" but without Haskins and Diamond.

The actor, who is currently keeping busy with a standup comedy career and also continues to act, has not commented about Haskin's remarks. When asked about his book, he told People in 2009: "The embarrassing parts are embarrassing for all of us, myself included."
