It was written in an hour. Someone (VP of a media buying service in Chicago) had left an offensive but lame story about a gerbil (no tube, no names, no flames, one person) on my desk in an attempt to irritate. I took that and rewrote to the perverse, offensive wonder above. Only difference between that and my original was the name of the Gerbil.
From when I wrote it in the 80s and placed it on his desk in reply he had to have shared it quite a bit.

I actually wrote this story in Chicago back in the early 80s
