Based Loosely On: 'Twas The Night Before Christmas
By: Major Henry Livingston Jr. (1748-1828)
T'was the night before Christmas and all around TIM,
Not a creature was stirring as he hummed a soft hymn;
The AE suits hung in the darkroom with care,
In hope that no aliens would come calling there;
The children were nestled all snug in their beds,
While visions of hyperspace danced in their heads;
And Liz in her nightdress and John all in white,
Had just settled down to sleep for the night.
When out in the Lab there arose such a clatter,
John jaunted at once to see what was the matter.
Away to the stun guns he flew like a flash,
Tore open the holster and threw up the catch.
The light of TIM's balls on the table below
Gave the banks of equipment a strange, eerie glow,
And then, to his wide-eyed amazement, he saw.
A tall, bearded man appeared by the door.
With thoughtful eyes, and robes so sublime,
John knew in a moment 'twas a Guardian of Time.
From an unknown dimension this stranger so tall,
He whistled, and shouted, and called to them all;
"Now, Michael! Now, Carol! Now, 'Lizbeth and John!
Come, Tyso! And Stephen! Where ever you've gone!
Andrew, and Hsui Tai come answer my call,
There's work to be done to the Trig with you all!"
With belts haphazardly slung round their waists
The long-distance jaunt they made with all haste.
Far across space to the Galaxy's end,
TIM 'pathed a good-luck to all his dear friends.
And then, in a twinkling, they materialized.
Sighed with relief, and looked round in surprise.
John crossed his arms to calm himself down.
"Let's get on with business," he said, with a frown.
Approaching them now, with arms open wide,
His robes luminescent, his eyes full of pride;
A bundle of presents he held with TK,
They relaxed in an instant, no jaunting away.
Chairbeing Timus didn't mean to seem rude.
He counted their number then looked on confused.
"There's somebody missing," he cried, after a time
"Kenny's back home, we left him behind."
Timus' eyes -- how they twinkled so merry!
His cheeks were all flushed, his nose like a cherry
His manner was cheery, his speech was quite slurred
To find Timus drunk seemed quite absurd.
"Apologies friends", he then called loud and hearty
"I've imbibed too much wine at the Trig's Christmas party."
"It was Peter's idea to bring you all here."
"Don't look so shocked, there's nothing to fear."
"No villains to thwart, no planets to save."
"You don't need to fret, don't look so grave."
And they laughed when they heard this, in spite of their anger;
Dragged from their beds, expecting real danger.
John smiled at his friends, as he waved them away"
The joke was on us." Was all he could say.
And they all fell about in hysterical mirth
Preparing to teleport back down to Earth.
The bundle of presents appeared at their feet.
With gift-wrap and tinsel all tidy and neat.
"A gift for each TP." Timus replied.
As the vortex of colour swirled in their eyes
And they heard him exclaim, as he faded from sight,
"HAPPY CHRISTMAS TO ALL, AND TO ALL A GOOD-NIGHT!"
