Been watching the World Cup? Whats that sound in the background. It sounds like the bleating of a dying animal. That my friends is what the native South Africans call a Vuvuzela ( pronounced Boo-Boo-Zay-La.) Actually what you are hearing are thousands of Vuvuzelas. Now you can fight back with this Ap and irritate your friends at the same time. And you can contribute to the massive beer fund of the inventor. I heard on the telly that over a million of this Ap has already sold! Haha
