When I was about 8 or 9 my dad had told me to hit his shin with my fist to feel how hard it was, then he would tell me that he had a metal bar put in his leg. When I would ask how or why he had a metal bar in his leg he would just laugh. Thinking he didn't want to talk about it I would just drop the subject. I wondered about that metal bar for quite a while. Now I know it was just his shin bone!
