well I heard this from mum
Bono was at this concert for the tennis, can't remember if it was wimbledon or the aussie open, and he stops playing, and starts clapping his hands very slowly.
The crowd is silent as he's clapping his hands, all watching him.
"Everytime I clap my hands, a child in africa dies."
The whole crowd remains silent, except for one bloke who yells out "stop fooking clapping yer han's then you bastard!"

And he gets really angry and throws a tanty.
