I read it somewhere, I'm sorry but I don't remember where. Maybe somebody here can help out my memory. It wasn't any place obscure. I also heard a version of the story last year where Takeda was knocked out. That version came from Ark Aizawa.
I heard it went something like this.
Takeda held the Okinawan's wrists down, and told him "now, try anything!"
So the Okinawan, in typical Okinawan fashion, ignored the wrists, jumped up and kicked Takeda in the face (Takeda wasn't that tall so it's pretty easy to imagine), knocking him out.
Another story running around was about Takeda's students begging him to show his skill at throwing shuriken.
Takeda eventually obliged, throwing three shuriken in a row at some wooden beam.
Everyone does the whole "wow you're so awesome" speal,
but from the corner some old geezer spouted "Any ass with half their wits could throw something pointy into a piece of wood!"
Takeda gets pissed and challenges the old man,
who promptly threw 3 coins into the beam of wood, forming a neat triangle
Takeda shut up, face went purple, and supposedly shuriken were never to be mentioned in his presence ever again
True or not?
Dunno, makes for a good story though.
Just means that there's always someone more skilled at this stuff.
