Bono is at a U2 concert in Dublin when he asks the audience for some quiet.
Then, in the silence, he starts to slowly clap his hands.
He says into the microphone, in a deep solemn voice...
"Just for a moment, think outside yourself... Outside this arena... Every time I clap my hands, a child in Africa dies."
A loud Irish voice from near the front pierces the moment...
"Well, ya stupid arse, stop yer fockin' clappin', then!"
