There are way too many quotes to choose from when it comes to The Breakfast Club. I can't pick just one, so here are a few:
Andrew: "We're all pretty bizarre. Some of us are just better at hiding it, that's all."
Allison: "Well, if you say you haven't, you're a prude. If you say you have you're a slut. It's a trap. You want to but you can't, and when you do, you wish you didn't, right?"
Bender: "You get along with your parents?"
Andrew: "Well, if I say yes I'm an idiot, right?"
Bender: "You're an idiot anyway. But if you say you get along with your parents, well, you're a liar too."
Bender: "But face it. You're a neo maxi zoom dweebie, what would you be doing if you weren't out making yourself a better citizen?"
Allison: "When you grow up, your heart dies."
