Between lectures at Uni, a horrible smell of drains was invading my consciousness, so I wrote this.
A medical text book photo I'd seen at someone's party got an honorable mention, too!

My lovely little turtle poo

you really do me proud

the way you climb the lavatory

while singing very loud

Your gentle fragrance winds around

the old Saint Marky's flats

then sidles down the drains again

to join the other pats

Oh dung of a small reptile

of smells which make us frown

with irridescent mottled green

and lumpy bits of brown

It reminds me of that gall bladder

with colours just like rust

the ooziness and squishyness

and all that pungent pus
