"Once there came a man"

Once there came a man Who said: “Range me all men of the world in rows.” And instantly There was a terrific clamor among the people Against being ranged in rows. There was a loud quarrel, world-wide. It endured for ages; And blood was shed By those who would not stand in rows, And by those who pined to stand in rows. Eventually, the man went to death, weeping. And those who stayed in the bloody scuffle Knew not the great simplicity.
