And here's one of many parodies:

THE NITE AFTER CHRISTMAS
Homer & Jethro

The baggy Christmas stockin's were lyin' on the floor.
The empty Christmas wrappings looked like there'd been a war.
The children weren't nestled or snuggled in their beds.
They went a-belly-whoppin' down the stairs on their sleds.
Then Ma tried on her Christmas hat an' felt just like a queen
Till Pa found out how much it cost and turned all red an' green.
The Christmas tree was lit up and so was uncle Si.
He thought he was a reindeer and insisted he could fly.
He hollered out, "Hey Blitzen, why don't you wait for me?"
Then landed right smack in the middle of the Christmas tree.

Uncle Harry was paradin' up an' down the hall
A-breakin' in new slippers a half a size too small.
My sister an' her boyfriend were fightin' toe to toe.
She caught him a-kissin' someone else beneath the mistletoe.
Then Pa got out his squirrel gun, the one he got from Ma.
Now he was only cleanin' it, but blasted down the wall.
The baby started cryin' an' Ma said, "Can't you see?
Christmas comes but once a year an' that's enough for me."

And then from in the fireplace there rose up such a clatter.
We ran into the parlor to see what was the matter.
The chimney was a-shakin'. The soot fell all about.
A voice within was bellerin', "Won't someone let me out?"
We looked up on the rooftop, an' much to our surprise,
We saw eight little reindeer but no one there to drive.
Then Pa poked up the chimney. He used a great big stick,
An' all at once came tumblin' down a feller called Saint Nick,
All covered up with ashes from his head right to his foot,
An' when he spoke, from out his beard fell twenty pounds o' soot.

"Since Christmas Eve I've been in there. I'd like to make it clear:
If you don't get your chimney fixed, I won't be back next year."
An' then as quick as lightnin', he sprang up to his sleigh.
He gave a little whistle an' soon was on his way.
But I could hear him holler as he drove out o' sight:
"A merry Christmas to you all, and to you all—goo-oo-ood night!"
