‘Twas the night before Christmas y por toda la casa,
Not a creature was stirring-Caramba! Que pasa?

Los niños were tucked away in their camas,
Some in long underwear, some in pijamas,

While hanging the medias with mucho ciudado
In hopes that old Santa would feel obligado

To bring all children, both buenos y malos,
A nice batch of dulces y otros regalos.

Outside in the yard there arose such a grito
That I jumped to my pies like a frightened cabrito.

I ran to the window and looked out afuera,
And who in the world do you think that it era?

Saint Nick in a sleigh and a big red sombrero
Came dashing along like a crazy bombero.

And pulling his sleigh instead of venados
Were eight little burros approaching volados.

I watched as they came and this quaint little hombre
Was shouting and whistling and calling by nombre:

"Ay Pancho, ay Pepe, ay Cuco, ay Berto,
Ay Chato, ay Chopo, Macuco, y Nieto!"

Then standing erect with his hands on his pecho
He flew to the top of our very own techo.

With his round little belly like a bowl of jalea,
He struggled to squeeze down our old chiminea,

Then huffing and puffing at last in our sala,
With soot smeared all over his real suit de gala,

He filled all the medias with lovely regalos-
For none of the niños had been very malos.

Then chuckling aloud, seeming muy contento,
He turned like a flash and was gone como viento.

And I heard him exclaim, and this is verdad,
Merry Christmas to all, y Feliz Navidad!

Not unexpected, it always gets an airing at this time of the year!

The average expat would need a dictionary to make sense of that

That's nice to know. I must be much better than average.
