The Wizard of Oz

At the U2 concert in Sydney, lead singer Bono 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." An Aussie voice from near the front pierces the silence, "Well, stop f*ing clapping, ya dick'ead."
