The "Saved By the Bell" cast got back together for "The Tonight Show" on Wednesday, and Jimmy Fallon walked the halls of Bayside High in one epic reunion sketch.

The late night host threw it back to the 90's with Mark-Paul Gosselaar (Zack), Tiffani Thiessen (Kelly), Mario Lopez (Slater), Elizabeth Berkley (Jessie) and even Dennis Haskins (Mr Belding) as the students prepared for a school dance.

"Bayside High: the home of babes, books and Belding," Zack said after making his entrance.

Zack made a b-line to his locker, where we all met his new friend Jimmy. "Hey, Jimmy!" he said.
"Hey, Zack!" Jimmy replied. "How's it going?"

Then, reciting the show's popular theme song, Zack said, "Oh, you know. Typical day. I woke up in the morning. The alarm gave out a warning. I didn't think I'd ever make it on time. By the time I grabbed my books and I gave myself a look I was at the corner just in time to see the bus fly by."
"It's. All. Right," Jimmy assured him.

0807-mark-launch-6The original cast members came in one by one, poking fun at their most memorable show moments. Slater showed off his ballet skills in a skin-tight black unitard, and Jesse relived her "I'm So Excited" caffeine pill freakout moment!

Next up, Kelly made her appearance with her baby bump in tow (Thiessen and husband Brady Smith recently announced they were expecting their second child). The best part? Zack bragged about getting her pregnant.

The only noticeably missing characters in the reunion were Lisa (played by Lark Voorhies) and Screech (played by Dustin Diamond, who was recently arrested for allegedly stabbing a man in a bar).

So far, no word on where Lark or Dustin were. Reps for both "The Tonight Show" and Voorhies were not immediately available for comment.

toofab caught up with Lark back in September, where she told us what she thought about the Lifetime biopic. While the actress has seemed pretty loopy in public in the past, we gotta say, she seemed in great spirits here:
