A caveat: This ranking only includes students, so don't expect to see any Finster or Grotke. And there are a few background players who have been left out. Sorry, guys.

Some of the worst kids in school, these hooligans usually just hang out together behind the school during recess. Some of them got more screen time than others (like Kurst and Mundy, who each had entire episodes dedicated to them), but they are all terrible by association. These kids have stolen, vandalized property, and more. GET THEM AWAY FROM MY BASKETBALL COURT.
