Time For Grub

<em>Hospital research has shown that leaving sterile maggots to clean a wound is much more effective

We like to feed on rotting flesh

To lick the suppurating sore

The body parts which we refresh

Are soon as fit as once before

If you are plagued by leaking pus

Or weeping sorely, call for us

What's bad is good, what's good is bad

Whenever we are out to lunch

And if you're purulent, we're glad

To offer solace with a munch

Our labours make you good as New

And happily, we're sterile too
