Football mania - I just don't get it!

I'm just waiting in the restaurant at our gym for Murray to finish up. Outside I can hear horns blowing, LOTS of loud people, and when I look down I see a sea of blue. Yes, there's a Chelsea football (or as we call it in American, soccer) game on today. There are literally hundreds of people crowding the street, and I don't even know if they won or not? Hmmmm but on the way into the gym I did see a man walking down the street with only shorts and shoes on with his ENTIRE body painted blue - wow, and a blue clown wig I must add. Now that's what you call a fan!
