This may not be the exact speech in English, since I usually watch a portuguese dub, but towards the end of the first Pokemon movie there is a scene in which, referring to the clone Pokemon he created, Mewtwo says something like " I understand now that the circumstances of one's birth are irrelevant. It's what we do with the gift of life that determines what we are".
I find it particularly amusing to quote this without revealing where it comes from, get the approval/agreement expressions and then say it's from the great philosopher Mewtwo.
