In Which is Had a Late Night Fright, but By Whom?

Unable once again to sleep, I sought
Relief in waters hot, of sulfur'rous smell.
Outside my door was waiting what, I thought,
Some kind of prank contraption. "What the hell?"
A radio antenna? Sculpture fail?
In silence, into darkness I stepped t'ward
The mystery. And then it moved! My flail
Of startlement near hit it. Almost gored
Upon a mighty antler, I withdrew,
Then, panting, frightened by a five-point buck
(That's on each antler; it's the West here). "Shoo!"
I said to him. I don't know why. As luck
Would have it, deer spaghetti was my lunch.
Was this revenge? I'd entertain that hunch.
