Stone(ball) Age

To the best of my knowledge, American football goes something like this:
A bunch of grown men chase around a little brown-and-white stripy ball across a green-and-white stripy field under the supervision of a couple of black-and-white stripy guys, and try to stick said little ball through a giant fork which may or may not be stripy. 
And feet are also involved somehow. 

I live in a weird country.
