Here's my explanation of why professional sports are satisfying and necessary

"There's some part of our reptilian brain that needs to conquer and dominate others. It's hard-wired into us. We used to satisfy this intense, unstoppable urge by actually conquering and dominating others. But now we have evolved and don't do that as much as we used to. So, even though it would be incredibly satisfying and rewarding for all of us to march on Dallas, burn it to the ground, sew the soil with salt so nothing ever grows there again, sell the citizenry into slavery, and take their gold and HDTVs, our society frowns on that kind of thing. So instead, we assemble a team of surrogates to represent our city-state and we give them a fearsome name like 'Giants' and we send them forth to do our conquering for us. And now there is only ritual humiliation and defeat, but it's all we've got and we enjoy it nonetheless. That's why we have professional sports.
