I recently ran across a very entertaining bit of fiction. It's a little bit borgesian, I guess, in that the story's protagonist is an idea rather than a person.
It's about a "chord tunnel" (an ancient concept orginally developed in the 18th century, also called a "gravity train," that pops up sometimes in science fiction) used for delivering burritos from San Francisco to New York City:
The Alameda-Weehawken Burrito Tunnel.
