Biography
In "Changes: The Big Prom: The Sex Romp: The Season Finale", The Secret Board of Shadowy Figures had figured out about Principal Scudworth's evil plan and they came to Clone High High School to kill him. Principal Scudworth distracted them with a conga line, but this would only hold them over for so long. John Stamos had an idea on how to save him and was willing to enact the plan, despite the way Scudworth treated him before. They led the conga line into the flash freezer and Stamos pulled the lever to freeze everyone, risking his own free will, as he would be frozen too. Principal Scudworth fled the scene, just in time to get off scott-free, leaving everybody flash frozen, for a long time, possibly forever, given that this was how the series ended.
