Science fiction author Isaac Asimov was an unapologetic punster. He wrote a short story called “Shah Guido G.,” referring to the story’s Atlantean ruler. The story ends on an anticlimax, and when a reader protested that it was “nothing but a shaggy dog story,” Asimov pointed out that the title “Shah Guido G.” could also be read as “Shahgui [i.e. shaggy] Dog,” indicating this had been his intention.
