"Oh, how will I release myself?"
A woman was trapped inside a room with a genie and a pen that had salt for ink. The genie said he would release her if she could trap him in the center of the room by drawing a circle with the pen around him that he could not escape from. He told her he would not be able to dissolve into smoke, but she must draw the circle so that he could not jump out of it. The woman freed herself. How?
