Psychic for a Day
Dustin Diamond's Screech was struck by lightning in the season one episode titled "The Gift," and naturally, instead of becoming seriously injured, he gained the ability to see into the future. Zack (Mark-Paul Gosselaar) and Slater (Mario Lopez) made sure to use Screech's psychic skills to their advantage, but eventually, his powers wore off.
The One
If there's one thing Zack Morris loves to do, it's meddling—especially when he knows the outcome will work in his favor. So when he decides that Screech is in desperate need of a girlfriend but fails to find him any potential suitors—thus leaving Screech too down in the dumps to finish their science project—Zack dresses in drag, and unfortunately for him, Screech falls in love.
Bad Accident
Screech inadvertently invents what appears to be a miraculous zit cream until everything quite literally blows up in his Kelly Kapowski's (Tiffani Thiessen) face.
Screech Takes on Sports
In what should be a surprise to absolutely no one, Screech is unable to successfully take Slater's place on the wrestling team. This, however, didn't stop Zack from suggesting he do so in order to win a bet.
Kelly's Got a Crush
Kevin was even a good wing-man, helping Screech tutor Kelly when she was failing science class. This set-up famously led to her falling for Screech, and while the pairing didn't exactly last very long, it did give us that scene of them sharing a milkshake together.
The Party of the Decade
Without Screech, Saved By the Bell fans never would've witnessed the iconic "Barbara Ann" scene in season two's "House Party" since it was his parents that were out of town.
Introducing Violet Anne Bickerstaff
"House Party" is memorable for a lot of reasons, but mainly because it introduced Screech's would-be girlfriend Violet, played by Tori Spelling.
Miss Bayside
Screech is the subject of yet another bet when it comes time for the Miss Bayside Beauty Pageant. Zack wages that he can get anyone to beat Lisa (Lark Voorhies), but when Slater picks Screech, he finds himself going to ridiculous measures to make sure he actually wins. And by ridiculous, we mean that when Kevin accidentally punches Screech in the face, Zack tries to tell everyone that it was Slater who hit him. The worst part? Zack's plan works and Screech wins the pageant.
The Talking Tooth
"Close Encounters of the Nerd Kind" sees Screech dress up as an alien so Zack can sell photos of him to a tabloid, but before we know it, the government is threatening to take him away out of fear that he's a real alien. Enough said.
Gumby Gone Wrong
Screech has never been subtle about his love for Lisa, but in season four's "Masquerade Ball," he sends her love letters as a secret admirer. And as it turns out, she's thrilled to read them—but only because she thinks it's Zack sending them. Confusion involving Mr. Belding (Dennis Haskins) ensues, leading to the costume ball in which Screech naturally dresses up as Gumby.
Screech's Revenge
Zack, Slater and the rest of the gang forgot Screech's birthday in season four because of course they did. Thankfully, Screech gets his revenge after being appointed hall monitor.
Graduation Day
Screech, being the genius that he is, earns the title of "valedictorian" come graduation day. However, because he knows how much it would mean to Jessie (Elizabeth Berkley), whose GPA is barely lower than his, he tells Mr. Belding to give it to her instead.
