NFL - I hate everyone that isn't the Redskins or the Colts. And when the Redskins play the Colts, I hate the Colts almost as much as I hate the Cowboys... but I could never hate anyone or anything as much as I hate the Dallas Cowboys and everything that is that organization.
NBA - Utah. I've always hated the Jazz. Always hated the Pistons. Can't stand the Mavericks. And I completely despise the Celtics.
NHL - I don't like the Penguins. I don't like anyone that Washington is playing. And I hate guys that try to fight Ovi. Don't do it to yourself.
MLB - I hate the Yankees, and the Giants just because they're the Giants.
Soccer - I'm a Chelsea fan, so I really hate Liverpool, Manchester United, and Arsenal.
