How we cite our quotes: All quotations are from Ferris Bueller's Day Off.
Quote #1
JEANIE: You're letting him stay home? I can't believe this. If I was bleeding out my eyes, you guys would make me go to school. This is so unfair.
FERRIS: Jeanie, please don't be upset with me. You have your health. Be thankful. Ferris makes a big face at her, and makes a Shh! gesture
JEANIE: That's it. I want out of this family.
Seriously—what's Jeanie's deal? Why is she determined to bring Ferris down for breaking the rules? Not to delve too far into stereotypes, but shouldn't she be more concerned with her grades or that cute guy in her social studies class or some totally tubular legwarmers or Reagan's foreign policy or something?

FERRIS: The key to faking out the parents is the clammy hands. It's a good non-specific symptom; I'm a big believer in it. A lot of people will tell you that a good phony fever is a dead lock, but, uh... you get a nervous mother, you could wind up in a doctor's office. That's worse than school. You fake a stomach cramp, and when you're bent over, moaning and wailing, you lick your palms. It's a little childish and stupid, but then, so is high school.
There you have it: At base level, Ferris thinks high school is childish and stupid. So it's time to shake stuff up.
Quote #3
ROONEY: What is so dangerous about a character like Ferris Bueller is he gives good kids bad ideas.
Rooney's worried that Ferris's determination to break the rules that he, Rooney, is trying to enforce will lead to copycats and undermine his authority. Given how the movie's narrative goes down, if we were Rooney, we'd be more worried about a neighbor seeing us trying to break into a student's house.
