Have You Ever Seen

Have you ever seen a sheet on a river bed?
Or a single hair from a hammer's head?
Has the foot of a mountain any toes?
And is there a pair of garden hose?

Does the needle ever wink its eye?
Why doesn't the wing of a building fly?
Can you tickle the ribs of a parasol?
Or open the trunk of a tree at all?

Are the teeth of a rake ever going to bite?
Have the hands of a clock any left or right?
Can the garden plot be deep and dark?
And what is the sound of the birch's bark?
