The lyrics you might have heard are taken from a song by The Smashing Pumpkins called Bullet with butterfly Wings. I wanted to put a link to their site, unfortunately the Smashing Pumpkins are no more and smashingpumpkins will redirect you to zwan A new band whose front man is Billy Corgan, who used to be part of The smashing Pumpkins. I think that is a shame
