I am agnostic on the vuvuzela controversy, but I will say their tone sounds a lot to me like the first note in Sir Duke, which is a frigging fantastic song to have stuck in your head all day. Seriously, try it sometime.
Also, I had a vuvuzela of my own many years ago, except I naively called it a "hockey horn" because I got it at an Ice Bats game. I wonder what happened to it. I mean, I don't want to unfairly implicate my former roommates here. All I know is I used to have one, and now I don't.
