They even put the unarmed strike on the weapons list (p149) so you also got the uber-bonus that the fist was both a manufactured AND a natural weapon.
...sadly the errata says that it's inclusion on the weapon list was a mistake, and it's not really a weapon after all.

So nobody else be ninja! Otherwise the law of conservation of ninjutsu ensures we will both be defeated...
