Twas the night before Christmas, when all through the lab
The wind it was howling and tilting the slab;

Seismic was ringing and microseism was too high
To lock the thing up was just not going to fly;
   
The staff were all tucked safe in their beds
While visions of more data danced in their heads; 

The wind it was blowing at just a mere gale
When the side of the building sounded like it was pelted with hail;

I sprang from my chair to see what was the matter
Away to the door to discover what was the clatter;

 As I opened the door, it was ripped from my hand with such speed, 
There was just enough time to duck flying tumbleweed;

So back to the control room I quickly retreated
And sunk into the chair, forced to admit I was totally defeated;
 
This Owl shift was done before it was over
With little to do but hope tomorrow would find LHO again in Observing clover; 

The doors are all locked, and the Guardian’s state is in Down
All that is left is to head back into town;

But the operator was heard to exclaim as he drove out off the site
HAPPY CHRISTMAS TO ALL, AND TO ALL A GOOD NIGHT!
