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 with it.

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 is nothing you can do about it!
