Darn Scott, you really are bored aren't you.
As for the lead, I still have a small black place in the palm of my hand where I stuck one of those yellow lead pencils in it about 25 years ago and couldn't get all of the lead out. It just kind of crumbled when it got in, probably from the blood. And I remember biting on the lead sinkers and chewing on the yellow pencils seemed a normal thing to do when taking a test and thinking. I believe that every person in class did it.
