This may be an oldie but here goes:
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 direction.
No matter how hard I try, I can't keep my foot and hand going in the same direction.
