Willow: Xander, what happened? Did Cordelia win another round in the broom closet?
Xander: You’re just a big bucket of funny, Will. I’ll have you know I was just accosted by some kind of, um, locker monster.
Giles: Loch Ness Monster?
Buffy: ‘Locker’ monster is what he said. But it wasn’t really a monster. It was, like, this big arm that came out of the locker, but then we opened it again, it was gone. Nothing.
Xander: This was right after Buffy’s history teacher starts doing some freaky channeling thing in class.
Giles: Ooh! Sounds like paranormal phenomena.
Willow: A ghost? Cool!
Xander: Oh, no, no. No. No cool. This was no wimpy chain rattler. This was ‘I’m dead as hell, and I’m not gonna take it anymore.’
Giles: Well, despite the Xander-speak, that’s a fairly accurate definition of a poltergeist.
Xander: I defined something? Accurately? Guess I’m done with the book learning.
