Where’s your head?
When someone isn’t paying attention, we ask them where’s their head. It seems as if this photo is taking this phrase literally. This person walking down the street seems like he’s literally lost his head, but we already know that can’t be right. Of course, it’s another optical trick our eyes are playing on us.

His head is simply bent forward at an angle that it becomes invisible. Can you imagine walking down the street behind this person? Even though we know his head is right where it’s supposed to be, this seems so real; if it were us, we might have called for help.
