Under the Bed

The first clue I got that
The monster was there
Was when the bed shifted a notch.
Then as I thought
I had only been dreaming
From under the bed came a cough.
The cough turned to choking
And hacking and wheezing
And soon a gurgle rose from below.
Boy, was I glad that
I left out my Teddy
Stuffed full of old chicken bones.
