Be kind and tender to the Frog

The Frog, by Hilaire Belloc

Be kind and tender to the Frog,

And do not call him names,

As "Slimy skin," or "Polly-wog,"

Or likewise "Ugly James,"

Or "Gap-a-grin," or "Toad-gone-wrong,"

Or "Bill Bandy-knees":

The Frog is justly sensitive

To epithets like these.

No animal will more repay

A treatment kind and fair;

At least so lonely people say

Who keep a frog (and, by the way,

They are extremely rare). 

—Elizabeth Periale
