HEADS OR TAILS requires something based on 'COMMON' this week. I'm pretty sure all of this is true, except, maybe, the last part!
THE COMMON PRAWN!
Oh Common Prawn! How dare they say
That thou art common? 'Fie!' I say!
Look at thy patterned camouflage!
Surely some Painter was in charge
To fashion curlicues and marks
In glorious verdant lights and darks!
Look at thy eye, so knowing, bright,
With watery wanderers in sight.
Look at thy whiskers! How they flaunt
Feeling each moist and murky haunt!
Look at thy tail! Thy jaunty steerage!
Common? Thou should'st be in the Peerage!
See how thou hoverest at a height
Which you have gauged exactly right!
How you tremble, how you dart!
What a work of art thou art!
(Though Aussies often say, it's true,
'Throw another prawn on the barbecue!')
