"..my feet have helped to keep the American shoe industry going, due to the money I have spent on my feet.
I have wore out seven hundred pairs of shoes, eighty-nine tennis shoes, forty-four summer sandals, and two hundred and two loafers.  The socks my feet have bought could build a knitting mill...Oh, my feet have helped make America rich, and I am still standing on them."

From "The Later Simple Stories" by Langston Hughes
