I used the think that too when he started showing up during the Royals post-season games, but there is more to the guy. I agree he is an attention loving whore, but he does donate a fair sum of money in the communities where he goes to the games. At least he did here in KC.
Right about the time the Royals were winning, there were two firefighters killed on duty here. He donated $10,000 to each of the families, so $20,000. I think he has also donated a ton of game tickets to people and things like that in all the cities he is in, plus he is known to pay for food and drinks for those around him.
