The In Crowd (1988)
Perry Parker: You know I... I talk to my teens about love, and I always say "This crazy thing called love, it makes you laugh, it makes you cry...but hey, man, it's what makes the world go 'round." Now, dying for love? Whoa! That's too momentous! I mean it's good for the books, but not for teens. Now, on the other hand, there's nothing wrong with a teen king or a teen queen FEELING like you could die for love. That way, you'd cherish every dance and you'd never waste a kiss.
Del: Okay, we're solving for "n".
Vicky: But that's a letter. I thought this was math.
Del: It's algebra. That is math.
