<P> Breakfast of Champions makes heavy use of metafiction, with Vonnegut appearing as the narrator / creator of the work, explaining why and how he makes this world as it is, changing things when and as he sees fit, and even being surprised by events . </P> <P> The novel also makes use of intertextuality with Vonnegut's other works . In addition to Kilgore Trout, characters from other Vonnegut books which appear here include Eliot Rosewater and Rabo Karabekian . Rosewater was the main character in God Bless You, Mr. Rosewater (1965) and a minor character in Slaughterhouse - Five (1969), while Karabekian later became the main character in Bluebeard (1988). Hoover's secretary, Francine Pefko, previously appeared in Cat's Cradle (1963), where she performed secretarial duties at General Forge and Foundry, in Ilium, New York . (Pefko also appears in "Fubar," a story released posthumously in Look at the Birdie .) Vonnegut uses the name "Khashdrahr Miasma" for a minor character, in reference to a character in Player Piano . The vicious guard dog, Kazak, was Winston Niles Rumfoord's pet in The Sirens of Titan (1959) and Selena MacIntosh's guide dog in Galápagos (1985). Many of Midland City's inhabitants reappear in Deadeye Dick (1982), which locates the city in Ohio . </P> <P> The title, taken from the well - known slogan for Wheaties breakfast cereal, crops up in a key scene late in the novel when a waitress, apparently ironically, says "Breakfast of Champions" each time she serves a customer a martini . Vonnegut, in his typical ironic manner, mocks the legal and copyright systems as he notes meticulously that Breakfast of Champions is a registered trademark of General Mills, Inc. for its breakfast cereal products, and that his use of the term is not "intended to disparage their fine products ." </P> <P> Vonnegut refers to himself as "Philboyd Studge" in the preface, a name which he claims his friend Knox Burger associated with cumbersome writing . The name appears to have been borrowed from a short story by Edwardian satirist Saki . ("Filboid Studge, the Story of the Mouse that Helped", describes the success of the eponymous breakfast food through bizarrely counter-intuitive advertising .) </P>
