I just don't get spectator sports

My roommate has people over for the football game, which means I'm currently avoiding that end of the house. There is a fair amount of noise emanating from a couple of people. Me? I don't get the appeal. There was a giant shouting match in my advisory over the Chargers and the Patriots on Friday (the two teams playing at the moment, for those not familiar with American football), so apparently some of my students are rather big fans. That, or they're just noisy and argumentative.
