Tiffany Thiessen and the 'Saved by the Bell' cast reunite on 'Tonight'

The Saved by the Bell cast reunited with "former classmate" Jimmy Fallon in a segment that aired Wednesday on the Tonight Show.
Fallon introduced the skit by revealing that not many people know where he went to high school and was later shown in the halls of Bayside High School with the likes of Mark-Paul Gosselaar (Zack), Tiffani Thiesen (Kelly), Mario Lopez (Slater), Elizabeth Berkley (Jessie) and Dennis Haskins (Mr. Belding).
During the flashback, Fallon tells his friends he won't be able to make it to the forthcoming Valentine's Day show because he's moving to New York to become a comedian.
"I love it here but I want to be on Saturday Night Live, host my own talk show and who knows... Maybe one day date Nicole Kidman."
Noticeably missing from the sketch was Dustin Diamond, who played Gosselaar character's best friend Screech. Diamond painted an unflattering portrait of his time on the show in his 2009 book Behind the Bell. On the subject of the book, Gosselaar said last year his experience on the show -- which ran from 1989- 1993 -- "was very positive."
