What's the stupidest thing you've ever done?

bono joke- real or not ? i dunno.

Bono is at a U2 concert in Glasgow when he asks the audience for some quiet.

Then in the silence, he starts to slowly clap his hands.Holding the audience in total silence, he says into the microphone:

"Every time I clap my hands, a child in Africa dies."

A voice from near the front pierces the silence:

"Well, stop fuckin' clapping then!"
