Xander: Here's your coffee. Brewed from the finest Colombian lighter fluid.
Xander: Aren't you supposed to be drinking tea, anyway?
Giles: Tea is soothing. I wish to be tense.
Xander: Okay, but you're destroying a perfectly good cultural stereotype here.
Cordelia: I demand an explanation.
Xander: For what?
Xander: Uh... inbreeding?
Oz: Any change?
Willow: He's delirious. He thought I was Buffy.
Oz: You too, huh?

Angel: Hadn't made any plans to weep over that one.
The Mayor: Well, I'd get set for some weeping if I were you. I'd get set for a world of pain. Misery loves company, young man, and I'm looking to share that with you and your whore!

Xander: I'm starting to lean towards the Hummus Offensive.
Oz: He'll never see it coming.
Buffy: (to Wesley) The Council is not welcome here. I have no time for orders. If I need someone to scream like a woman, I'll give you a call.
Principal Snyder: Congratulations to the Class of 1999. You all proved more or less adequate.
Buffy: My God. He's gonna do the entire speech.
Willow: Man, just ascend already.
The Mayor: (seeing the library full of explosives) Well, gosh.
Buffy: If someone could just wake me when it's time to go to college, that'd be great.
Oz: We survived.
Buffy: It was a hell of a battle.
Oz: Not the battle. High School.
