@Lobster:
It's an easy edit. Edit it to "Hey Yeah Ningen Sucker, Hey Yeah Ningen Sucker"
Easy
No, they shouldn't actually edit the song. It would be better if they just used the first opening through the entire series. (On the TV-version of course. If they removed the second opening on the DVDs, I'd be pretty annoyed, even though I kinda hated that second opening….)
