Quick funny exercise to lose 100 calories

1. While sitting at your desk, lift your right foot off the floor and make clockwise circles.
2. Now, while doing this, draw the number "6" in the air with your right hand.
 Your foot will change direction. . . . . . and there's nothing you can do about it! 
This will keep you busy for a while, trying to outsmart your foot, but you can't.
