This photo looks a little bit like Fridman had been at work on it before any request was sent to him! It's a happy scene, with a group of friends getting together to celebrate good times. The boy in the orange shirt looks a little uncomfortable, though. Because of a combination of the angle of his arm, and the angle of the camera, it looks like his head has slipped clean off his shoulders and rolled down the arm. At least he's smiling through the pain.
Fridman's job was simple - attach the head and the body back together. There was no direction about which part of the body the head should be attached to, so Fridman went with the nearest available limb. We think there's a lot to be said for this arrangement. Imagine how much easier it would be to look around corners, or on high shelves!
