watch the part when Goldfinger first demonstrates the knife-edged hat by throwing it at the statue. When the head falls off the statue, it is not very hard to it's left arm "bend" when hit by the head. There was obviously a joint on the arm to stop it smashing with the impact, but couldln't they arrange the angle of the head so that it didn't fall on the arm. Then this very obvious slip up could be avoided!
