Sarah Byrnes's "The Reason You Suck" Speech to Vice-Principal Mautz and Mark Brittain, during a runaway abortion debate. First she asks Mark if he really believes that all life is sacred. Then she asks him if the church that he and Mautz go to preaches that all life is sacred. Finally, she points out that neither of them has ever said anything to her during the entire time they've known her, kind or otherwise, and that the best they can do is tell Eric what to say to her. She ends by asking, "How can you people care so much about the unborn when you don't even give a shit about the born?" Really, it doesn't matter whether you're pro-life or pro-choice, it's hard not to be blown away by that speech.
Ms. Lemry delivering an epic Shut Up, Hannibal! to Vice-Principal Mautz after he blames the class in general, and Eric and Steve in particular, for Mark attempting suicide after Jody shames him in class by revealing that, despite his militant pro-life language, he forced her to get an abortion after they slept together.
Mr. Ellerby's arrival in Mautz's office after Mark attempts suicide. He puts the kibosh on Mautz's efforts to blame Eric and Steve for it, tricks Mautz into crossing a line that an educator shouldn't cross (attempting to inject his personal religious beliefs into the operations of a public school) and then informs him that Mautz's boss will hear about said line-crossing ASAP. And also ensures that Eric and Steve are not to be bothered again, ever.
