I loved the scene with Cordy and Wes in "Fredless"
Fred: But you said he loved her. And of course she's gonna love him back, 'cause he's so strong and handsome and he really listens when you talk. I-I mean, if you go for that sorta thing, why wouldn't it work?
Cordelia: Let me break it down for you, Fred.
[imitating Buffy]
Cordelia: Oh, Angel! I know that I am a Slayer, and you're a vampire and it would be impossible for us to be together, but...
Wesley: [imitating Angel] But... my gypsy curse, sometimes prevent me from seeing the truth. Oh, Buffy...
Cordelia: Yes, Angel?
Wesley: Oh, I love you so much I almost forgot to brood!
Cordelia: And just because I sent you to Hell that one time doesn't mean that we can't just be friends.
Wesley: Or possibly more?
Cordelia: Gasp! No! We mustn't!
Wesley: Kiss me!
Cordelia: Bite me!
Angel: [surprising everyone] How about you both bite me?
