Dog with two bones
He has this bone. It's the most important thing in the world; he carries it everywhere he goes. & one day he goes down to the water & he sees another dog with a bone reflected on the surface. It's identical. & he wants that bone too, so he opens his mouth to grab it & his bone falls in the water & it disappears. It's gone. & he's left standing there... looking at himself. & he has nothing.
