Emeralds and Rubies do not compare to slugs

Your long, green dress
Of moss-green silk,
Yoour lustrous hair,
As red as a beacon
Your emerald eyes,
As large as the sun;
Only lord knows
What you plot behind those eyes

Your hold as powerful as a tiger,
But your note as sweet as a lark
Prejudice cannot tell your plan
But choosing looks did not make me a man

A girl most fair of face,
But most grotesque of mind,
Poison my beverage;
before I poison yours
