One of my favorite Tool songs is Aenema... another one of those songs that makes you kinda step back and think. Disgustipated is good... it seems amusing at first, but then you think about what he's saying, and I think it's deeper than it appears at first listen. Hush is good too, and in a way kind of relates to the discussions that have been raging on this list lately ("I can't say what I want to, even if I'm not serious, I can't say what I want to, even if I'm just kidding"). Die Eier Von Satan is another amusing one, which may or may not have a serious meaning behind it... could have been just for fun. (Check out the translation of the lyrics if you download that one... one site is http://toolshed.down.net/lyrics/ - not the best one, but I lost my favorites folder with the really good lyrics page).
