Wow, thanks! That's the one. Funny how memory drift made it different in my head...but it has been many years.

How did you find that?

Now if someone can figure out the source, that would be even more amazing.

I believe it's in Vertigo Park And Other Tall Tales by Mark O'Donnell but it's appeared in the Spy magazine December 1987 before that.

If you search Google Books for "Do you not be happy with me as the translator of the books of you" and click on the Preview or Full View button you should see it in several places
