I am all tired out, said the mouth, with a pout,
I am all tired out with talk.
Just wait, said the knee, till you're lame as you can be—
And then have to walk—walk—walk.
My work, said the hand, is the hardest in the land.
Nay, mine is harder yet, said the brain;
When you toil, said the eye, as steadily as I,
O then you'll have reason to complain.
