Things to do when you're bored: Count ninjas

The week's 'thing' is a math problem from Naruto Fever.

The Set Up:
On your way to the training ground, you see a group of genins fighting. It's chaotic, you can't tell who's fighting who and you can't count how many ninjas there are. Your fists still hurt from beating up dishonest shopkeepers so you can't break up the fight either.
The Challenge:
Prove that at least 2 ninjas are fighting the same number of ninjas.
Oh and no, guessing is not allowed. Place your answers in the comment thingy, with full explanation of how you arrived at that solution.
