You are probably talking about the guy who announced the fights at the recent Yamma event. That was bad, just really bad. Even ignoring his voice the crap he came out with. . . the ref was even looking dissapointed.
I liked the small japanese guy who announced what I guess could have been seen as the pre-lims on some of the Pride cards. He was awesome, put his whole being into the announcing, like his life depended on it. Best part was he was so small and didn't move a muscle while doing it.
