A fellow from China was compere for a variety show when the lights failed and plunged the theatre into darkness. He stood on the stage and told the audience not to panic, and that they should all put their hands up in the air. As they did so the lights surprisingly came back on.
After the show, the stage manager said to him "How did you do that? It was amazing."
To which he replied "It's an old Chinese proverb, may hands make light work!"
