This is really strange…
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.
I told you so … and there’s nothing you can do about it! 
Hmm, didn’t work for me, I’m afraid.
Great, just great. My foot fell off when I was doing you’re stupid ‘trick’. You owe me a new foot, Mister.
And it’d better be a size 9.5.
I suggest you talk to Chimpy 
I didn’t quite change directions, but I did feel the urge, and slow down.
Hmmm. No change in direction for me, just a slight slowdown while my brain wondered “what the hell is he up to now”. Just for kicks, I rotated my right foot clockwise while drawing the 6 w/ my right hand, and rotated my left foot counterclockwise while making a backwards 6 with my left hand, all while experiencing no change in directions! I do have a mild headache now, and a twitching in my left eye.
I hope I didn’t break anything.
No, I think I managed to do it without changing direction. I’m not gonna spend all morning on this, but I did it reasonably okay after a couple of seconds…
I tried it, and my foot changed direction. I don’t know what’s up with the rest of you.
It’s that whole mirror image thing, Mirror Image. It didn’t work for me.
