This 16-second video of a little boy will leave you shocked and you may want to replay it just to confirm that your eyes did not cheat you. 

This video shows a kid hugging a person behind him, by twisting his whole body below his neck. Then he did it again, only a bit slowly just so that you may believe your eyes. He twisted as if his body has no bones. 

Enough talk, watch the video over here:
