Which episode did this occur in? I think it may have been that episode of Dragonball Z where one guy blasted another with a huge energy blast which kicked up a huge cloud of dust or smoke and everyone watching was saying "Surely he could not survive that!" or something along those lines and then the dust was blown away and the guy who was hit was still standing there unharmed and smirking.
No it was the other one where they stand around bullshitting about how big their dicks are followed by 10 mins of them screaming before finally attepting their super-secret-never-before-seen-ultimate-move.
On a side note DBZ Kai is a lot better than the regular DBZ but Dragonball the manga is better still.
I haven't seen anything from DBZ in probably... 10 years or more. And, I have to say... the drawings and animation are so atrociously terrible, that I regret any of the (albiet short) time I spent watching it in my younger days.
Oh, and that doesn't mention anything about the terrible storyline/characters either.
