Zack is flattered to be chosen as a pledge by the Rigmas, an exclusive club. Zack is willing to do just about anything in order to get the red jacket that is a sign of club membership. Most of his friends agree that it's worth it, except for Nicki. He has to do some embarrassing tasks and eventually even his friends think it's gone too far.

Meanwhile, Miss Bliss is acting principal for the week, while Mr. Belding takes over her teaching duties, so that she will have the experience necessary to take over if Mr. Belding is ever not there. Miss Bliss loves the job and seems to makes it look too effortless, handling every problem that arises with ease. Mr. Belding, on the other hand, has a lot of difficulty with his teaching duties. He feels even worse when he sees Miss Bliss handling his job so efficiently.
