Oliver Herford 
The Fairy Godmother-in-law [EPUB ebook] 

It is not always well to place
Unbounded Faith in Fairy Lore,
Believing that in every case
They all lived Happy evermore.
Stranger than Fiction though we deem
The Truth, it does not follow, too,
That Fairy Tales, because they seem
Still Stranger, must be still more True.
Far be it from me to assail
The Truthfulness of Fairy Writ,
But let us take a Well-Known Tale
And see what really came of it.
