For those of you with broken headmasters, there is a very easy fix I found. If the head separates, use something like a pin, sliding it into the small empty spot on the back of the head to lever it out. Once that is done, super glue the head back on to the body (but only put the glue on the headmaster's head, not the body, so he can still use his ball joint) then very carefully shave down the left and right sides of his head slightly. If you shave down too far, don't worry, just apply clear nail polish to the head, and he'll be fine! It worked perfectly for mine, and I'm certain it will for others!
