As the teaser clip continues, Thiessen and Gosselaar get some pics together as Lark Voorhies stands in the back jealous.

"She knows you like him," Elizabeth Berkley says.

When the girls get together for a ladies-only shot, Voorhies steps on Thiessen's toe, literally in retaliation for flirting with her crush.

While the guys are waiting, Lopez starts doing push-ups and Dustin Diamond follows suit, not wanting to be left out. After he can't keep up, Diamond gets in Lopez's face.

Then the whole cast starts arguing at the end.
