Here are a few ones I like from Blind Date
Gunn: Give me one good reason.
Angel: It'll be extremely dangerous.
Gunn: Okay.
Gunn: Whoo, Whoo! My God! They told me it was true, but I didn't believe em. Damn, here it is. Evil white folks really do have a mecca. Now, now, now girls, don't get all riled up. (Screams) Did you just step on my foot? Was that my foot you just stepped on? Are you assulting me up in this haven of justice?! Somebody get me a lawyer, because my civil rights have seriously been violated. Oh, I get it, y'all can cater to the demon... cater to the dead man... but what about THE BLACK MAN?!!!
Angel: How am I supposed to fight evil if they won't even put it behind bars?
Cordelia: What, "Helen Kellerus Homicidus?"
