I started watching non-Toonami Tenchi Muyo! and Outlaw Star and whew, was that some editing they did. They didn't even show an episode of Outlaw Star. Toonami is starting to get a little better though. I've heard hell a couple of times in Naruto and I'm truely positive, but I think I heard damn in an episode of Zatch Bell!
I even remember the last episode of YuYu Hakusho, they played on Toonami was completely unedited!
One Piece doesn't count, cause it was on Fox Kids and I don't trust their dubs ever since the Escaflowne fiasco y'all keep bringing up.
