Not quite, but I do like...

... the guy who wrote : (Ninja's) are actually silent assasins. e.g. they would dress up like a salesman to get into your house, and while they are pretending to sell you something they would look for holes and cracks to climb into, then at night they would come back and murder you.

They wouldn't just kill you on the spot.

The Best Ninja's ever (TM) includes how you could improve films just by adding ninjas. IE Perfect Storm is about "Sword Fishermen" and then it's got badly ps'd ninja's on the boat with George. *Very* funny...
