Sword thru Neck

The magician displays a wooden frame which has a big round hole through the center of it. A dazzling steel sword is also displayed. The sword is pushed through a slit in the frame and it is seen the sword passes right through the middle of the frame. The sword is removed, and a spectator is invited to place his neck in the frame. The sword is pushed through the frame once again where it apparently penetrates the spectators neck and emerges through a slit in the opposite side. The sword is withdrawn and the frame is removed. The spectator is left completely unharmed!
