Stupid is as stupid does. No wonder the Florida Marlins have no fans - it takes a stunt like this to even get anyone to show up. I love the part in the article below where the players had to wear ear plugs. That would not be good.
Seriously, though, I better never go to GABP and hear a vuvuzela. That's the quickest way I can think of to drive fans away (apart from a horrible bullpen).
