Death is a fisherman, the world we see
His fish-pond is, and we the fishes be;
His net some general sickness; howe'er he
Is not so kind as other fishers be;
For if they take one of the smaller fry,
They throw him in again, he shall not die:
But death is sure to kill all he can get,
And all is fish with him that comes to net.

Benjamin Franklin
