It all started with an amazing teacher.
Jerry Seinfeld once perfectly described the arbitrary nature of being a sports fan, saying:
"Loyalty to any one sports team is pretty hard to justify, because the players are always changing, the team can move to another city. You're actually rooting for the clothes, when you get right down to it."
Seinfeld is right in saying that being an obsessive sports fan can be a little silly, but he misses the wonderful feeling of community created among people who root for the same clothes.
