Here's a magic trick for you.
Think of a number between 1 and 10.
Really concentrate on it. Imagine the number in giant letters of stone, dominating the landscape, towering over you, filling your vision, your world. Think of nothing else but that number, and that number alone.
Now I will read your mind. That's the trick.
Your number is...
Now nine tenths of you are thinking I'm an idiot, while one tenth of you think I'm a genius.
Well actually now ten tenths of you think I'm a dick, but I had some of you for a moment!
