Vuvuzelas, those long, atonal trumpets played by thousands of soccer fans, are not getting a good reputation at the moment. So much so that there is a guide going around on how to silence them from FIFA World Cup broadcasts. It's a clever idea, and one I'm sure a few people will implement for themselves. A better idea, however, would be to implement it at the broadcast end, so the sound never gets to your TV in the first place.

PS - If you're of the polar opposite opinion on vuvuzelas, you may like to fantasize about Vuvuzela Hero.
PPS - I'd actually expect Vuvuzela Hero to look more like SingStar than Guitar Hero.
