After reading through the thread, I have to agree with a bunch of them.
Best: Zabuza, he kick major @$$, but Spike's death was good too. Yeah, you knew it was coming but it fit the series.
Funniest: Kakizaki. I love watching Max's head turn as the missle goes flying by to hit Kakizaki's valk.
Worst death because I was pissed about it: Hughes from FMA. He was my favorite supporting character!!! I think they did a good job since you actually CARED that he died and wasn't there specifically to be killed.
Hey, Max, why is the Uchiha clan deaths funniest?!?!
