When I started we wore bearskins and carried clubs to impose technicals. Oh yeah - since shoes weren't invented yet, we were barefoot. It was hard to tell the players apart since numbers weren't invented yet either and everyone was named "Og". We kept score with smoke signals and after each game, the winners got to eat the loser's mascot, usually a small animal.
BTW - I gave out so many technicals, my nickname was "T-Rex".
