The Substitute (E29)
Will Schuester is sick, which is cause for a substitute, Ms. Holiday (Gweneth Paltrow) to be called in. But Will is not the only one out for the day. Principle Figgins is sick as well, allowing Sue to take over as Principal. To make matters worse, the students aren't exactly missing Mr. Schuester, and Sue capitalizes on this, using it as excuse enough to fire Will and replace him permanently with Ms. Holiday. It's not long before Sue ensures that Prinicipal Figgins will never come back, and that she will now be the new Principal of McKinley High.
