Being the creator of the martial art we all love, and being so skilled as a martial artist overall (not to mention the philosophy side), we all understand the reverence that O-Sensei deserves. But, as a person, did he have a sense of humor? Not many here knew him personally, but would there be some kind of written tale from his students?
On a related note, would there also be a record of a funny mistake that he could have commited either on or off the mat? I know this would somehow take away some of the aura that there's to him, but he was still human.
