At a recent U2 concert in Glasgow, Scotland, Bono 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.”
From the front of the crowd a voice with a broad Scottish accent pierced the quiet …
“Well, fuckin stop doin it then, ya evil bastard!”
