I had a dead tooth removed once
(The dentist stole it. Didn't get to keep it.)
It was grey, stinking, and broken
An incisor, right at the front
(It's still there I can feel it. My whole face rots now.)
My sternum's an angry toothache
(Dentist won't fix that one.)
It is grey, stinking, and broken
My pericardium is bone
(To protect my heart and to throttle it, in equal measure.)
