I do like the Karl Shipiro ditty! Thanks for posting it.

This little Victorian ditty came from Songs for the Little Ones at Home, © 1852, p. 25-26:

'Twas God who made the little fly;
But if you pinch it, it will die!
My mother tells me, God has said
We must not hurt what God had made;
For God is very kind and good,
And gives e'en little flies their food;
And he loves every little child,
Who is kind-hearted, good, and mild.

It's a songbook with a great many such "treasures."

Cheerily,
Charley Noble
