Mother Goose OULIPO

I have wanted to live
Under a hill
Earth sheltered
Bermed and of
Constant temperature.
So it is logical for me
To play OULIPO
With Mother Goose's old
WOMAN under a HILL.
So I tried N + 7.
It gave:

There was an old WORD
Lived under a HIPPOPOTAMUS;
And if she's not gone,
She lives there still.

Hmm.  So I tried N + 7
On Edward Lear's nonsense.
Lear's nonsense made more sense.

So I went back to the HILL
In my paperback dictionary
Figuring it is more a game
Of literary potential
Than structured chaos
So I tweaked N + 7
And got:

There was an old WORD
Lived under a HINT;
And if she's not gone,
She lives there still.

And that to me
Is more satisfying.
