As off-color as the jokes in Dragonball may be, it was not aimed at a "general audience" as UkyoCE suggests. It was a show for little boys in Japan, but Japan has a much higher tolerance for butt humor in cartoons than the US does, so there you go.

Honestly, can you imagine anybody over 12 watching the drek that is Dragonball and finding it entertaining? I don't bloody think so.
