There's a certain kind of green fly
You know the ones I mean
The ones when doggie defecates
Come flyin' on the scene
They appear as if by magic
They appear as in a dream
With their emerald opalescence
And their iridescent sheen
When doggie doesn't defecate
These flies are never seen!
So where do green flies come from?
From some green fly machine?
From the carcass of a rotting steer
In some dried up ravine?
Where do green flies come from?
Do they hatch from a green fly bean?
Or when doggie poops does someone somewhere
Open up a screen?
And let the green flies fly about
To on her stool convene?
I'll never know the answer
But I judge from their cuisine
That the place the green flies call their home
Is a place that's none too clean!
