Buffy: Anya, when you were a demon, you granted wishes, right?
Anya: Vengeance wishes, on ex-boyfriends. I'd wish he was a dog, or ugly, or in love with President McKinley, or something.
Buffy: But someone could wish the whole earth to be different, right? That's possible?
Anya: Sure, alternate realities. You could have, like, a world without shrimp. Or with, you know, nothing but shrimp. You could even make, like, a freaky world where Jonathan's like, some kind of not-perfect mouth-breather, if that's what's blowing up your skirt these days. Just don't ask me to live there.
