Undermine

This is not funny.

Drop Your Coat O doctor,
We've got some work for you,
The king's gown needs a thousand stitches
Two to be made by you.

Leave your sword O soldier,
You've got a job to do,
The king has to butcher a thousand goats,
Two to be done by you.

Throw your brush O painter,
There's a lot of work to do,
The king's palace needs a thousand coats,
Two to be done you.

Don't go, son, to see the king,
He'll give you things to do,
Things that'll use all your skills,
But never give you your due.

Sorry Mama have to drop my coat,
Throw my brush and Leave my sword,
The king has pledged a thousand coins,
A string of pearls, a pot of gold.

The day belongs to the robot doctor,
Artists're an endangered lot,
Atom bombs used to pound foes,
We're down praying on our knees.
