|In the school cafeteria, the dean is making an announcement about the upcoming week-long school environmental awareness event called Green Week. Afterwards, the study group finishes taking a Spanish exam when Chang tells them to put their pencils down. Annie wasn't paying attention and continues writing. He stops her and drags her desk- with her still in it- out of the classroom. Shutting the door in her face, he addresses the class and assigns them all a one page essay. When Pierce asks him a question, he ups the page count to two. After Shirley objects, he ups the page count to six. When Britta attempts to compliment Chang, he interprets it as sucking up and assigns twenty pages for the essay due on Monday.
text=Back in the study room, the group is freaking out over Chang's latest insanity. All of them are busy with other classes and don't need the added pressure of a twenty page essay. Shirley is so worried about a presentation due in her marketing class that she accepts when Pierce volunteers to help. Troy and Abed chime in that they are already behind in a science project involving rats, one of Troy's phobias. Britta says that someone needs to talk to Chang and try to reason with him. Annie nominates Jeff who argues that he doesn't want to risk his grade by making himself a target of Chang's wrath. After Britta, Annie, and Troy wear him down, he grudgingly agrees to talk to Chang.
|In Chang's office, Jeff discovers that Chang has separated from his wife, and the resulting emotional void is responsible for the excessive work assigned to the class. To cheer him up, Jeff invites Chang to hang out, and Chang offers to cancel the essay for Jeff but not the rest of the class. Meanwhile, Troy and Abed are training their rat, Fievel, to respond to their singing when it escapes.
|The next morning, Jeff, hung over after a late night with Chang, tells the study group that he was unable to make any progress with their Spanish class. Pierce tutors Shirley in public speaking, but his generally derogatory and offensive manner discourage her, and she decides to just read her presentation off of notecards. During class, Chang adds a quiz for next Monday, but when he thanks Jeff for turning in the essay early, the group realizes Jeff sold them out. Jeff continues to spend time with Chang in his office, but Chang threatens to fail him should he spend time with other teachers. Jeff recognizes that Chang's emotional need is far greater than it first appeared.
|Abed and Troy are preparing for a water gun battle. They mock Pierce when he shows up with a tiny water pistol. They both stop laughing when he shoots them in their eyes with the pepper water that's inside.
