Why do we watch football?

I support West Ham football club. Not because I am a glory supporter (obviously), but because my uncle used to live in West Ham, and he basically forced me to support then, through the method of tickling. But I was 6 at the time so it's not as bad as it sounds.
Yesterday, I watched West Ham on BBC2, beat Birmingham 2-1, thanks to Ben Foster doing what I thought only Robert Green and Comference goalkeepers can manage. West Ham looked like they'd thrown it away when Birmingham equilised and Victor Obinna got himself sent off in the space of 5 minutes. Although to be fair to Obinna, if you are going to be sent off in one of the most important matched of the season, back healing someone in the bollocks is the way to go. Obinna, you were more entertaining than the rest of the match put together.
Why do we support football teams, and watch football. Well on the face of it, given the little amount of action that happens in the vast majority of football matches (come on, where else could you get 75,000 people into a stadium to watch a team beat another team 1-0 and still come away happy), we must like football because we are so fat and lazy, as a collective, that we just want to see people running around and wearing themselves out. Well this isnt the actually reason. Although the fat and lazy bit is correct...
We go to watch football because we want to win something, without moving a single muscle, well maybe a couple, just to get the pie down you. What's the best way to win something with no effort...let someone good at it do it on your behalf. Do premier league footballers deserve to earn 6 figures every week? Well the supporters don't deserve it
