Can You Keep Ideas In Your Feet?

If men are made from mainly meat and bones
Where will my ideas find a feeling quite like home
My thoughts begin in other places than my head
They often times will fill my empty stomach
And they've also started in my aching feet
(They find another spot when I'm asleep)
I've heard that all my thoughts are from an ancient Greek
However, Greek or feet,
The place I like to keep my thoughts the most
is on my tongue
and rhyming as I speak
