I honestly never saw what was so big about this line, in general. Both the Ocean and FUNimation dubs change around a lot of lines, in DBZ, so what makes this line so much different from some of their other changes?
Maybe its the fact that Brian overacted on this line as Vegeta, but he did that with a ton of other lines for Vegeta, as well. Hell, he pretty much overacted Vegeta's role, with his voice, in general.
