Ohhh, I lie, I have to add these:

BigWheel Spike and Angelus recruiting Dru to find out what Giles knew because "I don't want to be cleaning librarian out of the carpet." The whole scene where Dru seduces Giles into believing she's Jenny. Beautifully played.

The classic "love's bitch" scene--the whole thing, beginning with, "We killed a homeless man on that bench, on through "all slime and antlers," and Spike's immortal, "it's blood, children," speech, and Buffy and Angel's uncomfortable reception of the truths Spike was saying.

At which point, I found myself with a deadly blue woobie.

There's just no woobie quite like a fallen god.

Him falling to his knees after she dies in The Gift.

That was fantastic. My all time favorite Spike moment. He was a monster with no soul, and he was wracked with grief at Buffy's death.

So for small moments, most have been mentioned.

But to add:

Riley saying "... but she doesn't love me." Oomph.

Finding out that Chaos Demons are, indeed, all slime and antlers. Ha.

The look on Connor's face after Faith gives him a verbal smackdown. It's like he's been hit between the eyes with a very small hammer, and he quite liked it.

Willow in The Pack. When I think Buffy says "They ate Principal Flutie". And Willow say "Ate him up?"

Most of my favourites have been mentioned already, but - I love Oz telling Willow that when he kisses her, he wants her to be kissing him.

Also, the end of Killed by Death, when they're sitting around asking Joyce to get them stuff, and she's bogarting the cheesy chips. Makes me smile every time.

The moment when Spike realizes Ressurected!Buffy is not the Buffybot.

In the BuffyBot episode:

"You thought I was a ROBOT?"

Actually, the real scene, which is now making me laugh and laugh:

Xander: Buffy, we need to talk.
Buffy: (alarmed) What's wrong? Is Dawn okay?
Willow: Dawn's fine.
Xander: Buffy, we care about you, and we're worried about you. The way you're acting, the things you're doing-
Anya: It's wrong.
Willow: Wait. This shouldn't be about blame.
Buffy: Blame? There's blame now?
Willow: No, there's only love. And ... some fear.
Anya: Which is kind of thrown by the you having sex with Spike.
Buffy: The ... who whating how with huh?
Anya: Okay, that's denial. That usually comes before anger.
Buffy: (angrily) I am not having sex with Spike!
Anya: Anger.
Xander: No one is judging you. It's understandable. Spike is strong and mysterious and sort of compact but well-muscled.
Buffy: (firmly) I am not having sex with Spike! But I'm starting to think that you might be.
Xander: (scoffs) Buffy, I saw you. Anya too. (Anya nods) We saw you and Spike ... (gestures vaguely) with the straddling.

The Buffy Bot enters, looking offended.

Buffybot: Spike's mine. Who's straddling Spike?

She strides up next to Buffy, who stares at her in amazement.

Buffy: Oh my god.
Xander: (amazed) And so say all of us.
Buffybot: Say, look at you. You look just like me! We're very pretty.
Willow: Two of them!
Xander: Hey, I know this! They're both Buffy!
Buffy: (annoyed at him) No, *she*'s a robot. She acts just like that girlfriend-bot that Warren guy made. You guys couldn't tell me apart from a robot?
Buffybot: Oh, I don't think I'm a robot.
Anya: She's very well done.

Huh. I sound like a Spuffist. Still, he used to have quiet moments.

He did, and that was what made me love the character so - the quiet shining through the bluff and swagger.

I've always liked the very chipper "We're very pretty," 'cause, well, they are.

"Intervention" -- Spike telling Glory that Bob Barker is the Key. (ETA: And when the real Buffy kisses Spike at the end of the ep.)
