Sweet fuck, could a more succinct summation exist? I think not:
"Once upon a time, there was a game called paofpopafsoj.
There are four teams. The referee is on one of the teams. The referee decides what the rules are, how points are awarded, and who wins. All disputes are settled by the referee. The referee’s authority is final and absolute. The referee records the score in a book. Whichever team wins gets to choose the referee for the next game.
What could possibly go wrong?"
