Bono, lead singer of the rock band U2, is famous throughout the entertainment industry for being more than just a little self-righteous
At a recent U2 concert in Glasgow, Scotland, he asked the audience for total quiet

Then, in the silence, he started to slowly clap his hands, once every few seconds
Holding the audience in total silence, he said into the microphone, 'Every time I clap my hands, a child in Africa dies.
A voice with a broad Scottish accent from the front of the crowd pierced the quiet... 'Well, stop doin it then, ya evil bastard!'
