First, a video for you, then a joke.
Bono, the lead singer of the 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, foockin stop doin it then, ya evil basturd !"
