Ah and I was hoping no one would respond to this thread but as you
have made a fool of yourself let me point out why everyone is laughing
at you.

http://en.wikipedia.org/wiki/Ninja

 "A ninja (Ǧ?) or shinobi (Ǧ?) was a covert agent or mercenary in
feudal Japan who specialized in unorthodox warfare"

Note the phrase "in feudal Japan". The ninja is a wholly Japanese phenomena

Facts, dontcha just love them :)
