Screech asks Zack to write a love letter from him to Lisa.

Zack is embarrassed by some older students who invite him into a “cool” club. Miss Bliss and Mr. Belding trade places for a week.

Zack and Slater both try to obtain Kelly as a dance partner before the big dance contest at The Max. However, Zack goes with Jessie instead. Lisa also has a date for the dance, but when she sprains her ankle, he backs out. Screech agrees to dance with her in the contest despite her injury. In the end Screech and Lisa win with their dance move, coined by Casey Kasem as “The Sprain”.

Screech is hit by lightning and afterwards has the ability to see into the future, which Zack and Slater use to their advantage. Zack uses his power to place bets with Slater, including a bet that he would get an A on the history exam, but Screech’s power wears off before he can help Zack cheat.

With the big dance approaching, Zack is determined to get Kelly to go with him. He goes to extreme lengths and bugs Jessie’s room when the girls are having a sleepover. Unfortunately the girls find out and decide to get their revenge. They make it seem as if Kelly is mentally insane.

Zack decides that Screech is in desperate need of a girlfriend and sets about finding him one. However, when there isn’t anyone willing, he dresses up as a girl and goes on a date with Screech, and has to act fast when Screech takes a liking to him. He ends up dumping “Bambi” after Zack makes strict rules for him.

When Slater’s dad is reassigned to Hawaii, Zack sees it as the perfect opportunity to get Slater to move away so all the attention from the ladies comes back to him. Zack ends up making it seem like Slater is dying to the girls, but it backfires when Kelly finds out the truth after Zack steals Slater’s trophy.

When Ms. Simpson injures her back, a substitute teacher named Tony Crane takes over her class at Bayside. However, when all the girls, including Lisa, Jessie, and Kelly, fall for Mr. Crane, Zack and Slater become jealous. They try to make it seem like he’s married. He follows along later after he finds out what they were trying to do.

In order for Kelly to go to a George Michael concert, she has to pass her science test. Zack persuades Screech to tutor Kelly, a ploy which is more for his benefit than for Kelly’s. When Kelly and Screech become closer, though, Zack gets jealous and regrets his set-up.

Everyone is put into pairs for a class assignment to act out married life, so they can be prepared for marriage as adults.
