I'm almost positive you watched the Ocean (I think thats who did it.. I saw some clips of it..) dub of GT. They've already released their version, and funimation isn't done dubbing yet.
PS- while we're on the subject, I was starting to think Funi was doing a good job dubbing Z, but I've lost all respect for them. Has anyone heard the english opening that funi is slapping on the show? It's rap for gosh sakes! I have nothing wrong with rap, I'm just not to fond of it, and the song sounds REALLY bad. Also, they are skipping the first 20 episodes when they air it on cartoon network, and they will not be available until after GT is done aring.. ONLY in a box set. You can not get them seperately.. only in the entire box set of GT *sigh*
