Ep 6. The Common Denominator

Brandy tells Cam the "Glamazon Vote", where they vote for a leader, is today and turns down his offer of help due to his reputation declining after losing his presidency. Biffy figures out a way he and Lee can figure out if cloning teachers is taking place: talking to the the 15th Graders. The 15th Graders build Beth a trebuchet for her, due to Chopper being attracted to her. Biffy pretends to set up a date after school for Chopper in exchange for some information, some photos of a teacher's weight fluctuations further convincing them of the cloning. Lee and Biffy decide to go to Brandy's apartment building to find the teachers. Brandy has trouble with the vote as the other two Glamazons are too dim and afraid of Kimmie to be persuaded to vote against her. Kimmie subtly tells Brandy she's onto her and Cam eventually goes out to Brandy's place to help. When Lee and Biffy get to the building, they are invited into Mr. Langhorne's room but are knocked out by gas when Langhorne goes to lie down. After waking up to find Langhorne gone, they cover their mouths, lie on the bed and find themselves in a chamber with sleeping teachers in pods. After touching one of them and turning him to dust, activating an alarm, they climb back out. Kimmie is voted the leader again, Cam arriving right after voting ends and Brandy is kicked out of the Glamazons for voting for herself and insulting Kimmie afterwards. The episode ends with Biffy hypothesizing all the teachers may be clones. Lee realises what he is implying and denies his mother is a clone. Biffy points out the recent evidence: they saw teachers in the pods, Langhorne's room smelled like the staff room and the Taz stole the file on Sue Ping. Lee jumps on his parents bed to prove that his mother is not a clone, with nothing happening.
