I got this in an e-mail and I had to share it.
How Smart is your right foot?
You must try this--it's amazing and takes only seconds. How Smart is Your Right Foot? This is so funny that it will boggle your mind. And you will keep trying it at least 50 more times to see if you can outsmart your foot, but you can't.
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. I told you so...And there's nothing you can do about it!!
Try it with your left too, it just requires more concentration then I'm willing to give to fight it.
