"When I was a child, I used to speak as a child, think as a child, reason as a child; when I became a man, I did away with childish things." The Japanese culture doesn't have such a 'hang up'. They realise there is a time to act like a man, and a time to let it all hang out and act like a child agian. Those walls are slowly fading around the world as people are finding out that 'toons can be just as fun for adults and acting goofy just for the fun of it isn't a mortal sin.
