One of the classic kids' anime shows that made its way across the Pacific was Monkey Magic, and it was full of fighting, jokes . . . and very deep lessons about philosophy and ethics. I love this one in particular, where Monkey meets Buddha, and learns that he is but a puny dot in the universe occupied by Buddha, and that selfishness causes pain to others. Complete with trippy animations as Monkey dives deep into Buddha's mind and makes terrifying discoveries about the nature of being. The best part is that the whole thing is based on an actual Buddhist story.
Here's the bouncy opening credit sequence to this seriously weird (and tragically forgotten) show.
