I just don't understand them.
I'm always amazed when my roommates aren't all pumped up for the nights big game. How can you not want to watch every second of something like the NCAA tournament? Or not be sitting in front of the TV on Saturday/Sunday during football season?
I don't have a problem with people like that, as long as they just admit that they aren't into sports. Don't be all trying to pretend like you know whats going on when you don't have a clue, and don't try to act interested if you aren't. But I still don't understand it.
