Piece of wood

All I am is a piece of wood
Cut from something living
Touch me I don't feel too good
I'm cold, but I'm not shiverin'

You say I do not know, to say

All I am is the tail of a worm
Cut from something squirming
Pinned to the earth
I twist and turn
For soil and roots I'm yearnin'

All I am is a fingertip
Some angel's placed in cotton
And the syphalactic doctor says he'll make it fit
But all his learnin' he's forgotten
