OK let's start at the beginning

When fishes roamed the sea

They swam around before anything else

In ten million years B.C.

Then one day they decided

To evolve into vertebrates

And a few came out of the water

And got drunk to celebrate

Soon, well when I say "soon" I mean

A couple million years

They evolved into various quadrupeds

With legs and things and ears

And about a trillion aeons later

They went all civilised

And built lots of bombs and council flats

That reached into the skies

The moral of this tale, you see

We are descended from the fish

And if we progress much further

We'll put our lives at risk

We're starting to destroy ourselves

With pollution, war, and greed

When food and sex and water

Is all we really need

When "sink or swim" is the choice you get

You cannot swim forever

You need support to keep you alive

Us fish must swim together!
