Spongebob Squarepants - The Magic Moving Chalk
Near the very beginning of the episode, Squidward is talking about his art class. It shows a shot of him first from quite some distance. There are two chalks over to the right of his head and an eraser to the left of his head. When it zooms in on him, there is one piece of chalk beside the eraser. When it cuts back to the far away shot, the chalk and eraser are back where they were. Does someone move the chalk when the camera switches?
