I say we make this the new most popular thread. I'll start:

Chuck Norris can simultaneously fight off an unlimited number of ninjas. This is because if the Law of Conservation of Ninjitsu. The amount of Awesomeness of all the ninjas stays the same, just divided between the ninjas. This also explains why the last ninja is so much tougher than all of his brothers.

n=N/p where n=specific amount of ninjitsu per ninja, N=total amount of ninjitsu available, and p=number of remaining ninjas.

I need help with the equation describing why Chuck Norris' toughness goes down through the course of the fray.
