Heh..
When I was in 5th grade, shop class (Oh boy..),
Had a pencil on the inside pocket of my jean jacket point facing up.
Dropped a tape measure and bent over to pick it up..
Pencil stabbed me in the rib cage.. still have some of the graphite in my ribcage and an entrance/exit scar with some graphite that The doctor (And myself) did not get out.
