Joan wanders into the Mock Trial Club room and sits down in front of Glynis and next to Grace, who says, "Shut up…why are you here?" Joan says, "Well, because we're creatures of conscience…but you…?" Grace: "Victim of the ruling class." The teacher, the aforementioned Armin Shimerman, a total HITG!, announces cheerfully, "Hear ye, hear ye. Mock Trial is now in session. I'm Mr. Harbison, civics teacher and legal enthusiast!" He taps his gavel on his desk for emphasis. Glynis beams, "He even has his own gavel!" I think she might wet herself. Joan mutters, "Oh, this is gonna be ugly." Grace: "If he pulls out one of those wigs, I'm outta here." Mr. Harbison's attention lands on her: "You're…Polk. Miss Hoder sent you because you're failing history." Grace: "Not failing. Refusing to answer questions about our so-called justice system, which everyone knows is a corrupt capitalist farce." He decides she should be the defense attorney. Grace pleads that she just wants to do her time and leave. Joan's smirking like crazy. Mr. Harbison cautions Grace: "Not without a fair trial!" He laughs at his own joke, but doesn't get much love from the peanut gallery. He wanders around the classroom expositing, "Mock Trial was created by the American Bar Association to teach youngsters how the court system works." As he walks around the room, two guys are eating sandwiches. I guess this is a lunchtime thing. Probably relatives of Chewy's. Frink: "Where's that obnoxious yearbook kid? Wouldn't he be in this club?" Harbison informs the club that they're going to try a case based on a fairy tale: Jack and the Beanstalk. Joan's confused; she thinks it's obvious that Jack murdered the giant. Grace takes umbrage: "It was self-defense, dude. The giant was trying to eat him." Joan sneers, "Jack broke in and stole stuff. That's…breaking and entering and murder one." Aw, Pops would be so proud. Mr. Harbison asks if he's hearing the sound of a prosecutor. Joan apologizes and says her dad's a cop. But the teacher's mind is made up: Joan and Grace are opposing counsel, and he hands them pamphlets called "A Basic Approach to Law." Joan says she really doesn't want to, but he just welcomes her to Mock Trial and bangs his little gavel again.
