Some real deep thoughts needed here

Vince

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

What gems are found on the crown of his head,
who crosses the bridge of his nose?
Can a man while shingling the roof of his mouth,
use the nails on the end of his toes?

Can the crook of his elbow be sent to gaol?
if so what would he do?
and how does he sharpen his shoulder blades?
I'm sure I don't know , do you?

Could you sit in the shade of the palms of your hands,
And play on the drum of your ear?
If the calves of our legs eat the corn on our toes?
Then why does it grow on the ear?
