here are some sweet ninja moves i learned in china town in victoria:
Death Grab:take hands and squeeze face till eyes pop out(very graphic)
Leg breaker: break leg with stick or hands
tounge twister: reach in opponents mouth and twist tounge till it pops out
Break someone in half: kick real hard till person cuts in half(practice on neighbor's dog first)
Karate chop: make hand look like knive and hit enemie's(s) neck so it gets real sore
