Hmmm. I don't quite get it. The first message, posted in 2004 by Terry Allan Hall, requests the lyrics. Then in 2016, Rabs poosts this link:

It's apparently the Website of Terry Allan Hall, with lyrics by Terry Allan Hall. Go figure. Anyhow, here are the lyrics:

Grandma Got Knocked Up by a Reindeer
(Terry Allan Hall)

Grandma got knocked up by a reindeer
Said it was the best sex of her life
For 40 years, she's been schtupping Grandpa
Now Prancer's gonna make her his new wife!

Lately Grandma's been so moody
Since Grandpa ran away
With a 19-year old stripper
Can't blame her that she kinda felt betrayed

But she was different Christmas morning
She was joyous, bright and gay
We assumed she was enjoying
All the fun involved with this Happy Holiday

(chorus)

She no longer moons for Grandpa
Say's he wasn't great in the sack
Says now she's getting better
Buck-lure is her aphrodesiac

Still the family is pretty worried
And they honestly have a reason
And I wonder about my new Uncle
And how we'll keep him home during Hunting Season

(chorus)
