I received this parody of Clement Moore's masterpiece via email back in the  mid-1990's, the author is unknown to me. Kimberly Powell at the About Genealogy  page also has it on her site.
'Twas the night before Christmas
'Twas the night before Christmas
When all through the  house
Not a creature was  stirring,
Not even my  spouse.
The dining room table  with clutter was spread
With pedigree charts  and with letters which said...
"Too bad about the data  for which you wrote;
Sank in a storm on an  ill-fated boat."
Stacks of old copies of  wills and such
Were proof that my work  had become too much.
Our children were  nestled all snug in their beds,
While visions of  sugarplums danced in their heads.
And I at my table was  ready to drop
From work on my album  with photos to crop.
Christmas was here, and  such was my lot
That presents and  goodies and toys I'd forgot.
Had I not been busy  with grandparents' wills,
I'd not have forgotten  to shop for such thrills,
While others bought  gifts to bring Christmas cheers,
I'd spent time  researching those birth dates and years.
While I was thus musing  about my sad plight,
A strange noise on the  lawn gave me such a great fright.
Away to the window I  flew in a flash,
Tore open the drapes  and yanked up the sash.
When what with my  wondering eyes should appear,
But an overstuffed  sleigh and eight small reindeer.
Up to the house top the  reindeer they flew,
With a sleigh full of  toys and 'ole Santa Claus, too.
And then in a twinkle,  I heard on the roof
The prancing and pawing  of thirty-two hoofs.
As I drew in my head,  and bumped it on the sash,
Down the cold chimney  fell Santa--KER-RASH!
"Dear" Santa had come  from the roof in a wreck,
And tracked soot on the  carpet, (I could wring his short neck!)
Spotting my face, good  'ole Santa could see
I had no Christmas  spirit you'd have to agree.
He spoke not a word,  but went straight to his work
And filled all the  stockings, (I felt like a jerk).
Here was Santa, who'd  brought us such gladness and joy:
When I'd been too busy  for even one toy.
He spied my research on  the table all spread
"A genealogist!" He  cried! (My face was all red!)
"Tonight I've met many  like you," Santa grinned,
As he pulled from his  sack a large book he had penned.
I gazed with  amusement--the cover it read
Genealogy Lines for  Which You Have Plead.
"I know what it's like  as a genealogy bug."He said 
as he gave me a great  Santa hug.
"While the elves make  the sleighful of toys I now carry,
I do some research in  the North Pole Library!
A special treat I am  thus able to bring,
To genealogy folk who  can't find a thing."
"Now off you go to your  bed for a rest,
I'll clean up the house  from this genealogy mess."
As I climbed up the  stairs full of gladness and glee,
I looked back at Santa  who'd brought much to me.
While settling in bed,  I heard Santa's clear whistle,
To his team, which then  rose like the down of a thistle.
And I heard him exclaim  as he flew out of sight,
"Family history is Fun!  Merry Christmas! Goodnight!"

To all, I wish a very Merry Christmas, and I hope Santa brings you a special gift for your family history.
