"While sitting at your desk, lift your right foot off the floor and make clockwise circles. Now, while doing this, draw the number "6" in the air with your right hand. Your foot will change directions and there's nothing you can do about it!"
What so hard about it. All you have to do is start making your 6 were you normaly would end it.
That maybe cheating, but you never said which direction the 6 had to go.
