Running with ... Pencils?

When I was growing up my little brother was mad at me and decided to run down the stairs of our house with a sharpened pencil and jab it into the back of my head. Note that back then the pencils had actual lead in them. While I laugh now, it wasn't so funny when my three year old did the same thing - but with a duller pencil - to her twin. All because she was mad at me. Who would of thunk that those types of things come back around?
