Principal Waller becomes Ray and Travis' substitute history teacher for the week. The topic being covered, The Boxer Rebellion, is one Travis is well versed in, due to his many years living in the far east. When Waller's version of events doesn't sit well with Travis, he goes on a mission to prove to Waller that history is a messy, complicated affair with more than just the victor's side of the story. Waller and Travis become entrenched in a rebellion of their own. While Waller is playing teacher, Kim Carlisle is trying to sell Cougar Radio calendars to raise money for the station. Robbie gets caught in the middle when he takes a stand as Question Mark against the calendars, but as Robbie does his best to help Kim sell them.
