Anya: The power of the Wish made me a righteous sword to smite the unfaithful.
Xander: Well, hey! Good luck with that. Hope it works out for you.
Anya: You know, you can laugh, but I have witnessed a millenium of treachery and oppression from the males of the species and I have nothing but contempt for the whole libidinous lot of them.
Xander: Then why you talking to me?
Anya: I don’t have a date for the prom.
Xander: Well gosh. I wonder why not. It couldn’t possibly have anything to do with your sales pitch?
Anya: Men are evil. Will you go with me?
Xander: One of us is very confused, and I honestly don’t know which.
