For an Amorous Lady by Theodore Roethke

The pensive gnu, the staid aardvark, accept caresses in the dark;
The Bear, equipped with paw and snout would rather take than dish it out.
But snakes, both poisonous and garter, In love are never known to barter.
The worm, though dank, is sensitive. His noble nature bids him give.
But you my dearest have a soul, encompassing fish, flesh and foul.
When amorous art we would pursue, You can with pleasure, bill or coo.
You are, in truth, one in a million. At once mammalian and reptilian.
