People, this is real funny...you gotta try!

LEFT BRAIN RIGHT BRAIN
This is one of the strangest things I have ever encountered.
Left brain, right brain.
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 and there's nothing you can do about it.
