Product Without A Head

There once was a box,
That was lost from Fort Knox,
A box of brown cardboard,
They got from an asylum ward.
It came from a man,
Who claimed that his Nan,
Years ago, had stolen it,
And had given it to him, to hide it.
 
He was to await the arrival of a visitor,
Some sort of monster,
That had already purchased the box,
And was ready to collect said box.
He assumed by "monster", she ment criminal,
Not really some kind of unearthly animal.
 
A curious object it was,
But when they asked to see it, he made quite a fuss,
So they called him "dangerous",
Locked him away "to be cautious",
To take a look in the box, mysterious.
 
And back, they took it, to Fort Knox.
The size of a shoe box,
Full of bullet holes,
And inside, was another box,
Full of just rocks.
But when they looked away,
Just momentarily,
A scream was heard, loud, and blood curdling,
What really was that thing he had been hiding?
 
In but a moment, the object changed,
It morphed into something deranged,
A little body with a price tag,
Lying atop a bloody rag,
And a sticker that reads "As is- without head",
That's indeed what it said,
Though they couldn't believe their eyes,
His Nan, had been in on the lies.
 
Also inside, were traces of ectoplasm,
And a sight, not so welcome...
A torn piece of paper,
That fell out, with a flutter,
With the words "AREA 51" in big, bold, letters,
That, just increased their dangers.
 
And with a crash,
A window it did smash,
The creature from another world,
Managed to kill all, as away the box was squirreled,
Before the creature got hold of it,
And to this day, no one knows the location of it,
As the alien kills all in his way, to find it.
