"Watch for Flying Bananas"

Have you ever wondered with all the action movies filled with ever so skillful ninjas why you have never meet many in everday life or any at all?  Yes, I know they are ever so stealthy and are the masters of concealment but surely you would run into one ever once in a while.  The mystery was solved for me by a third grader.  I quote, "To be a ninja you have to train for fifty years.  To be an expert ninja you have to train for one hundred years."  So to improve my chances of meeting a ninja I'm going to visit several retirement homes in the area and throw fruit at some of the oldest people and see if they pull out a samurai sword and cut the fruit in half in midair.
