Sci Fi Saturday: The Artifact

The airlock wasn't broken; all was well
Except the man who'd passed through it, who'd fooled
Evaluations by the score. We fell
For all his lies - and yet he broke no rule
While breaking space-walk records. It was known
He was a little odd, but no one guessed
When he stayed late again and have a groan
Of happiness, that he had passed his test.
He'd outsmarted the safeguards back on Earth
But kept his secret until now, when he
Undid the locks and clasps and cables. Mirth
Soon froze upon his naked face as, free
Except from physics, he became space junk
Like any other. All your theory's bunk.
