Classic Poem

From east to west let it be told,
I'll give the honest lumps of gold,
If all the rascals will agree,
To pay, each one, a pin to me;
I will without delay pay down,
To ev'ry man of sense a crown,
If all the silly fools that live,
Will each to me a farthing give —

I could write down upon my thumb
The good that half mankind have done;
And all the wisdom I have heard,
Would scarcely fill a calling-card —
A pigeon's wing would be enough,
To feed all who are men of worth;
But would you give the knaves a treat,
You may cry " come, good folks, and eat!"
