John Stamos is an American actor, best known for playing Jesse Katsopolis on the sitcom Full House. He is the worst enemy of Principal Scudworth, after he "stole" the title of prom king from him in high school. He appeared in the season finale, "Changes: The Big Prom: the Sex Romp: the Season Finale".
He arrives to the Clone High Winter Prom to catch up with Scudworth, but happens to show up as Scudworth is about to be crowned prom king (a vote that Scudworth sabotaged), causing Scan Grade to instead give the award to him. Scudworth confronts Stamos, who gives him the crown, but Scudworth instead stabs him in the eye with it. When The Secret Board of Shadowy Figures arrive to terminate Scudworth and take the clones away, Stamos distracts them by initiating a conga line. He ends up sacrificing himself to save his old friend, using the last of his strength to pull the lever to the flash freezer with himself, the SBSF and all the students still inside.
