why does madara has to be serious just because he is a legend? i don't see jiraya being serious all the time...or tsunade...even the third acted a little foolishly remember the harem jutsy naruto used on that juunin while the hogake was watching him with the crystal?i'll say all the strong people act like fools in naruto-world...except kakashi...also acting like a fool is the best way to deceive someone don't you know that?
