Of course it hits when I have to work all day to beat a deadline tomorrow. But still! Over the course of about fifteen minutes, ruminating on (of all things) a throwaway comment by Gary Gygax, which was itself based on a throwaway comment by Robert E. Howard, I suddenly had what I regard to be a Very Cool IdeaTM for a protagonist about whom to write one or many novels, enabling me to bring together both my sense of humor and my love of weird fantasy, without simply writing a pastiche of Douglas Adams.
In short, without wanting to be premature, I may have found my magnum opus. :)
We shall see how this develops. No details just now — I don't want to jinx it. But wish me luck!
