Mr. Hankey: Everything that lives on earth poos in some way
And that's how the cycle happens, each and every day
Just look at the green green grass and the birds up in the sky
It's all here because of poo, and now I'll tell you why
Grass is eaten by the cattle, which is eaten by women and men
It fuses with their bodies and [bad word] poo again
And that poo goes through the sewer, where it's dumped into the sea.
And it's eaten by the plankton, and [bad word] the fishes' meal.
And then that bigger fish with the poo still inside
Swims up near the shore and gets eaten alive
By the grizzly bear that poos on a dead piece of sand
So it can spring to life and [bad word] food for the land
It's the poo of the antelope, the poo of the giraffe
It falls onto the earth and [bad word] the blades of grass
The grass is eaten by the cattle, [bad word] out the other end
To make food for the humans and start all over again

You see, son? You're not an insignificant part of life. You are life.

Cornwallis: But how can I be that giraffe and blade of grass, and a human? I don't control what they do.
Mr. Hankey: Just like your heart beats without you thinking about it, so, too, your giraffes and your humans do what they do without you even thinkin' about it. But it is all one life form. It is all… you.
Cornwallis: I think I see now.
I'm the poo of the antelope, that flows down to the ground

Mr. Hankey: [bad word] the grass of tomorrow
Cornwallis: Yeah
Mr. Hankey: Which the grazers turn around
Cornwallis: So I'm the leg of a leopard and the wings of a hen
Mr. Hankey, Cornwallis: Which [bad word] dinner for the human and turns back to poo again.
That's the Circle, the Circle of Poo!
