How weird (cool) is your body?

I've always been able to do this thing where I can interlace my fingers together, climb over my two hands interlocked like that (so that my hands are now behind my back as if I were being arrested) and then bring them over my head again without letting go of the grasp between my two hands.

So if I'm ever in handcuffs and they are behind my back I can basically bring them to my front.
