My L'Ailee tends to pick really twisted and funny ones, and her current one is so hilarious I'm almost jealous:
Rob: "Bucky...those animals are *endangered*.

I think quotations.about.com is a good place for quote-mining, but I usually tend to get mine from life and reading and lyrics and TV. I have quoted everyone from Susan B. Anthony ("I always distrust people who know so much about what God wants them to do to their fellows."), to Ethan Zohn (that sexy curly-haired Survivor winner, who said to another contestant, "Look, you're a bigot and that's okay."), to Mos Def ("I am a fighter and a lover"), to Rita Mae Brown ("I think the reward for conformity is that everyone likes you except yourself.") to Juliana Hatfield ("A heart that hurts is a heart that works.").
Where did you get yours?
