House Flies

Now what? I utter under my breath
What's next on my list of subjects?
I know, I'll write about house flies!
That should stir things up I suspect

Much maligned, they have a purpose
Not sure what that purpose might be
So I looked it up on good old Google
They're the greatest carrier of disease

That's really not what I expected to find
Thought they had some redeeming factor
Seems that's all these insects are good for
If you can, run 'em over with a tractor

Swat 'em, stomp on 'em, any old time
Try aiming for the females if you can
Each can lay approximately 500 eggs
It's for the overall good health of man!

Question: If a fly loses it's wings,
would we then have to call it a “walk”
