The 2010 FIFA World Cup in South Africa.

And those vuvuzelas... they're so annoying, I just want to turn up the TV and listen, but I can't.

FIFA is reportedly planning to ban these vuvuzelas altogether, but by the time they get around to it, the 2014 World Cup will have already started.
It's strange, but they don't bother me that much. I feel more sorry for the players on the field and in the stadium; they probably have that sound ringing in their heads long after the match is over.
