So, here, for my DS (and my memory), are the words and author:
The Crocodile
If you were to stand on the banks of the Nile
In the sweltering sun and with sand in the air
You'd have to beware of the bold crocodile
For he and his friends would surely be there.
With a lashing and thrashing of terrible tail
And a snapping and clapping of horrible jaws
He searches for food and should he find your trail
He wouldn't say no to a body like yours.
They say he can live for a great many years
With his crocodile skin like an armoured car
Because of his teeth there is nothing he fears
When he's seen in a zoo, you are safer by far.
And now that my story is nearly complete
Of the crocodile's habits I'm sure you might dream
But remember, the only one you'll chance to meet
Is the lizard who lives on the banks of a stream.
Peter Jenkyns (1921-96)
