Xander, to Jenny Calendar, trying to justify the gang’s penchant for hanging out in the school library. “I Robot, You Jane.”
Hey, I may be a cold-blooded jelly doughnut, but my timing is impeccable.
Oz to the gang in Beauty and the Beasts.
“I’ve always been amazed with how Buffy fought, but in a way, I feel like we took her punning for granted.”
Xander, episode 1 of season 6. If that’s correct, then
“If you tell anyone we had this conversation, I’ll bite you.”
Spike to Andrew, after discussing snack preferences (love that onion blossom) in a S7 ep whose name escapes me.
“You were a Boy Scout?”
Nope. 
It is Xander, but it’s in Season 3, episode 1, Anne, to Willow and Oz
[quote]
You were a Boy Scout?"*
is Spike to Adam in New Moon Rising.
“That much quality time with my mom would probably lead to some
quality matricide”
Buffy, speaking to Amy, about excessive cheerleading training with her mother.
Well, this one is going to be obvious now, but it’s a great line:
You’re like Tony Robbins, if he was a big, scary, Frankenstein-looking (pause) … you’re exactly like Tony Robbins.
By the way, Lsura’s quote was from season one, “The Witch”, a rare case that I actually know the episode title!
Spike, to Adam, realizing why demons were willingly following Adam’s lead, in “The Yoko Factor.”
** But I want Oz to get an A, and, oh, one of those gold stars.**
Willow, of course. To Buffy, I believe, in …Phases?
And I need a quote. Let’s see…
“Good hellbeast. You’re a lazy hellbeast, aren’t you? Yeeesss. You’re just gonna stay right there while I…Run for my life!”
Yay! One I know!

And I have one.
“Darn your sinister attraction”
Buffybot to Spike in…crap I just watched it…um, the ep where Spike gets the Buffybot.
“Line!”
The Buffybot ep is Intervention. (Oh, Spike! You’re covered in sexy wounds!) Interesting tidbit, Nicholas Brendon was sick during some of the filming of that episode, so in some scenes Xander is played by his twin brother Kelly Donovan. Donovan also appeared in some scenes as Xander in the evil twin ep.
–Cliffy
“Line!” was the new quote, BTW, not a call for the ep title (interesting as the tidbit was).
I believe that Kelly Donovan was also his regular stunt man.
its a double header…
Cordelia to unseen prompt
and later in the same episode
Angelus to Cordelia…
Angel season 1 episode titled… “Eternity”

shaky premise - - but a good episode…
and I put out…
This isn’t mere dust. This is son of dust
Cordelia, while cleaning up the old hotel that becomes their new office.
Things involving the computer fill me with a childlike terror. Now, if it were a nice ogre or some such, I’d be more in my element.
(There are many days when I feel exactly the same way.)
Anya to Willow when Willow is fixing Buffy-Bot.
**I mean, this place is NORAD, and we are at DefCon One. **
Xander, to the gang, describing the magic shop and the arrival of the gang of motorcycle demons in “Bargaining”
Well, this is new territory for me. I mean, my valentines are usually met with heartfelt restraining orders.
