This is probably my favorite DBZ scene.
If this isn't proof of the Japanese version's superiority to you, then I reccomend dying in a fire.
I recently ordered the three first DBZ movies on DVD in a fit of reckless nostalgia. I found a great deal, though, since I bought the original DVDs, with the Ocean dub. The movies escaped the early censorship the series got, and I get bilingual discs that include the superior Ocean cast (with Peter Kelamis, Goku in season 2)! Fuckwin.
