what the hell is the thing about the bucket full of phlegm? dont get me wrong, i love this song and this whole album, but that line doesnt make any sense to me. the only thing i can think is that when he felt so inclined to write this song, he happened to be sick and alone in his room with a bucket full of phlegm. can anyone shed a little light on this subject for me?
