This is mostly for the funny (ie. "You get fangs, I'll get horny... I mean..."), but can include moving lines (like Johnathan's speech at the Prom)... anything you liked, really.
Tara: I go online sometimes, but everyone's spelling is really bad, and it's depressing.
Xander: But let's not try to forget, we're also your friends. Anya: I'm not. Buffy: Then why are you here? Aside from getting rescued, what is it that you do? Anya: I provide much needed... sarcasm. Xander: Um, that would kinda be my job, actually.
Buffy: What should we do with the trio over here? Should we burn them? Willow: I brought marshmallows.
Xander: You're considered somewhat cool. Oz: I am? Xander: Is it because you always tend to express yourself in short, non-commital sentences? Oz: Could be.
Yeah, Willow, but Oz had a similar line earlier in the same season where he said something like "I'm storming away now... I know it's pretty dramatic, but it's something I've got to do..."
