My favourites were Bad Girls and Doppelgängland. I loved this scene in Bad Girls:
Wesley: (very nervous) Oh, God! (looks around desperately) Oh, God!
Giles: (calmly) It doesn't seem too promising, does it?
Wesley: (trying not to panic) Stay calm, Mr. Giles. We have to stay
calm.
Giles: (brimming over with sarcasm) Well, thank God you're here. I was
planning to panic.
Wesley: (looks at Balthazar) What *is* that thing?
Giles: That would be your demon. You know, the dead one?
Wesley: There's no need to get snippy.
Balthazar finally turns his attention to the Watchers.
Balthazar: Bring them closer.
Two of the Eliminati grab them and shove them closer.
Balthazar: You know what I want.
Giles: If it's for me to scrub those hard-to-reach areas, I'd like to
request you kill me now.
He is hit hard in the back for his insolence.
Giles: Ow.
Wesley: (beginning to panic) Are you out of your mind? This is hardly
the time for games!
Giles: Why not? They're going to torture us to death anyway.
Balthazar: (snickers happily) You're not wrong about that. (wheezes)
Wesley: Now, hold on. We-we-we can deal with this rationally. We have
something you want. You have something we want.
Balthazar: Hmm... A trade. Intriguing. (considers) No. Wait. Boring.
Pull off his kneecaps!
Two of the vampires grab him.
Wesley: (horrified) NOOO! No, no, no! (they let go, he caves) The
Slayer g-gave it to someone. A tall man, a friend... a friend of hers. I
can tell you everything.
Giles: (under his breath) Quiet, you twerp! They'll kill us both.
Wesley: (panicked) But I'd like to have my kneecaps.
LMAO!!!! Sorry, long quote, but the pair of them crack me up in that scene. : rotflmao I also like the quote from Willow in Doppelgängland:
"That's me as a Vampire? I'm so evil and, skanky, and I think I'm kinda gay."
