Willow Rosenberg: We have to figure out how to kill this thing and we need to do it fast.
Xander Harris: Uh... hot lava.
Willow Rosenberg: That's for a heretic.
Xander Harris: Oh, yeah. Yeah, yeah, okay. Uh... Ooh-ooh! Bury a potato... No, that's for warts. Who *writes* this stuff?
Cordelia Chase: I've got the solution right here.

Cordelia Chase: "To kill a demon... cut off its head."
Xander Harris: Oh, yeah-yeah-yeah. We'll, uh, find Ms. Calendar, then we'll decapitate her. Hey, she'll be the first headless computer teacher in school. You think anybody'll notice?
Cordelia Chase: Do you know what you need, Xander, besides a year's supply of acne cream? A brain.
Xander Harris: That's it! Twelve years of you and I'm snappin'! I don't care if you're a girl or not. I'm throwin' down! Come on!
Cordelia Chase: I've seen you fight. And don't think I can't take you!
Cordelia Chase: Give it your best shot.
Willow Rosenberg: [yelling] *Hey*! We don't have time for this! Our friends are in trouble. Now, we have to put our heads together and-and get them out of it! And if you two aren't with me a hundred and ten percent, then get the hell out of my library!
Cordelia Chase: We're sorry.
Xander Harris: We'll be good.
