The Mysteries of Anatomy

Where can a man buy a cap for his knee,
Or a key for a lock of his hair?
Can his eyes be called an academy
Because there are pupils there?

In the crown of his head, what gems are set?
Who travels the bridge of his nose?
Can he use, when shingling the roof of his mouth,
The nails on the ends of his toes?

What does he raise from a slip of his tongue?
And who beats the drums of his ears?
And who can tell the cut and the style
Of the coat his stomach wears?

Can the crooks of his elbows be sent to jail?
And, if so, what did they do?
How does he sharpen his shoulder blades?
I'll be darned if I know. Do you?
