I love both of those quotes! My fav Spike quotes though are:
GILES: We'll all get our memory back, and it'll all be right as rain.
SPIKE: Oh, listen to Mary Poppins. He's got his crust all stiff and upper with that nancy-boy accent. (everyone looking at him) You Englishmen are always so... (pauses) Bloody hell! (ticks off on his fingers) Sodding, blimey, shagging, knickers, bollocks, oh God! I'm English!
GILES: (puts glasses on) Welcome to the nancy tribe.
SPIKE: You don't suppose you and I ... we're not related, are we?
ANYA: There is a ruggedly handsome resemblance.
(Giles smiles at Anya with pleasure.)
GILES: (to Spike) And you do inspire a, um ... (Spike walking out from behind the counter) particular feeling of ... familiarity and ... disappointment.
(Spike walks up to Giles, scowling. They look at each other.)
GILES: Older brother?
SPIKE: (scoffs) Father. (Giles looks outraged) Oh, god, how I must hate you.
GILES: What did I do?
SPIKE: There's always something, and what's with the trollop? (indicates Anya)
ANYA: Hey!
GILES: Her?
SPIKE: I saw you! Sleeping together.
GILES: Resting together.
ANYA: Look! (holds up her hand with the engagement ring) It's okay. We're engaged.
GILES: (smiling) Oh.
ANYA: It's a lovely ring.
SPIKE: Oh, great, a tarty stepmom who's half old Daddy's age.
ANYA: Tarty?
GILES: Old? You little twerp, I'm young enough to still get carded.
GILES: I'm, uh, called Rupert Giles.
ANYA: (smiling fondly) Rupert.
SPIKE: Rupert! (giggles)
GILES: You're not too old to put across my knee, you know ... sonny. (Spike still laughing) Anyway, what did I call you?
SPIKE: Um...
(Spike examines his clothing, finds a label on the inside of his suit jacket.)
SPIKE: 'Made with care for Randy.' (looks at Giles angrily) Randy Giles? Why not just call me 'Horny Giles,' or 'Desperate for a Shag Giles'? I knew there was a reason I hated you!
GILES: Randy's ... a family name, undoubtedly.
SPIKE: (to Giles) You never showed me affection like that!
(Giles looks confused.)
SPIKE: ...I'd wager.
BUFFY: Well, we need to figure out what's going on. We need to get help.
SPIKE: Looks like Joan fancies herself the boss.
BUFFY: We have a kid here-
DAWN: A teenager.
BUFFY: A teenager. And we have no idea what's wrong with us. I think a hospital's our best bet.
(Anya is fiddling with Giles's clothing.)
GILES: Uh, yes, let's, um, let's head out.
(They all start walking toward the door. Xander offers Willow his arm, and after a moment she takes it.)
BUFFY: Any suggestions on how we're gonna get there?
SPIKE: Dad can drive. He's bound to have some classic midlife-crisis transport. (puts arm around Giles's shoulder) Something red, shiny, shaped like a penis.
SPIKE: Wait up!
(He runs up to Buffy, grabs her arm. She turns, grabs his arm with her other hand, flips him over onto the ground. She kneels, straddling him and holding him down.)
SPIKE: Bloody hell, what are you doing?
BUFFY: (staring at him, realizing) You don't know who you are.
SPIKE: Right, none of us do, and we're being chased by-
BUFFY: You're a vampire!
SPIKE: (shocked) How can you say - I, me, a vampire? No.
BUFFY: Check the lumpies. And the teeth.
(Spike puts his hand up to his face, feels his forehead and teeth. Buffy sits up but remains straddling him. He lifts his head to look at her.)
BUFFY: I kill your kind.
SPIKE: And I bite yours. (drops his hand from his face) So how come I don't wanna bite you? (Buffy frowns in confusion) And why am I fightin' other vampires?
(Spike gets a look of revelation on his face, lifts himself up onto his elbows.)
SPIKE: I must be a noble vampire. (Buffy looks dubious) A good guy. On a mission of redemption. I help the hopeless. (chuckles) I'm a vampire with a soul.
BUFFY: (frowning) A vampire with a soul? (beat) Oh my god, how lame is that?
Basically I love the entire eppy of Tabula Rasa! Its the best!
