Do you have a pencil "tattoo"? Share it with us! So a ton of people are taking on to Twitter to show off their lead marks they received, most as children, from being stabbed by a pencil. I was so amused by this because I have a mark on my leg from getting a pencil stuck in it when I was a child. I've always wondered why the heck it's never gone a way, and I'm glad I'm not alone.
