Bud Webster is a big know-it-all who can empty a room in three minutes just by blabbing trivia about science fiction and fantasy. As a writer, he's responsible for the Bubba Pritchert stories published in ANALOG, and also for numerous articles about the history of the field.
He is also the Estates Liaison for the Science-Fiction and Fantasy Writers of America (SFWA), making it easier for publishers to legally reprint works by classic sf/fantasy authors.
I was going to write "Don't read this if you are a Christian", but maybe you should. It'll only take you about ten minutes. Then again, if you do read it, don't expect to come out of it unoffended.
This short story is an interesting extrapolation of the events in the New Testament, with a less-than-hopeful bent. Did the big experiment go badly?
