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!

Welcome to the meat market
The Carlton Banks of Bayside High makes Lisa feel like an airhead, which is totally unfair because he's not even that smart. (Judging by his pronunciation of The Hunchback of Notre Dame, he obviously thinks the book takes place at a college in Indiana.) Also, Jessie continues to be a psycho (although we kind of see her point this time), and Zack learns a Very Important Lesson about fat people that lasts all of 30 seconds.

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.
