Let's take a trip to the Wild West, Bayside style
Considering that the Bayside universe is approximately the size of a postage stamp, is it any wonder that Zack is constantly running into his ex and the guy she dumped him for? After trying to make Kelly jealous by dancing with a member of the tribe of the orange scrunchie at the Max, Zack realizes there's only one thing to do: He challenges The Sketchinator to a duel at high noon! Or, he gets over it. But the first one would've been so much more fun!

Lisa Turtle: The thing malpractice suits are made of
Zack suffers a near-fatal injury after...um, running into Mr. Belding in the locker room. Fortunately, he's under the care of the most incompetent candy striper in Bayside Hospital history, Lisa Turtle. Go into the light, Zack! And take Lisa with you before she harms any more patients.

You can call me Albert Clifford
Based on the highly scientific results of a Completely Implausible Science Project called the "Love Machine," Jessie flies into a jealous rage that gives Glenn Close's character in Fatal Attraction a run for her money. Yet somehow she still ends up with Slater. I guess those two aren't ready to get rid of their beards just yet.
