Shackled and seldom heckled

Fishing lines and nets
Jettisoned by those whose head
Was full of shit and vile detritus
Walking evil mostly dead
All this vile and inhuman tackle
Lodges in the sandy shore whales and deep sea denizens pick up
The vile shackles instantly
Carry it upon their bodies
Losing their ability
To swim across the many oceans
Tied in knots invariably
Man is really his own ugliness
Creating in an instancy
Disadvantage torrid darkness
The great whales bound up they be
In fishing nylon broken hearted
We need the rescue parody
