Not really stubbing my toe, but fairly recently I had sharpened all my pencils so they were sharp. I also left them on the floor. One foot stepped onto the main part of the pencil, the part you hold, so that foot was fine. The other foot though, since the pencil was being held in place, moved forward and I got stabbed in the heel with a very sharp pencil. I still have a scar. I also got stabbed in the hand with a pencil recently, also my fault.
