From an email going around, I tried it, it's true:
While sitting at your desk, lift your right foot completely off the floor and make clockwise circles.
Now, while doing this, draw the number 6 in the air with your right hand.
SPOILER ALERT - DO NOT READY ANY FURTHER UNTIL YOU TRY WHAT IS DESCRIBED ABOVE, SERIOIUSLY
Ok, so the deal is that your foot will change direction as you draw the 6 in the air, and it's very hard to stop from happening. Any medical types out there have a clue why?
