References to Isaac Asimov's Three Laws of Robotics have appeared in a wide variety of circumstances. In some cases, other authors have explored the Laws in a serious fashion. Other references, like those made in the satirical newspaper The Onion, are clearly parodic. Print media The satirical newspaper The Onion published an article entitled "I, Rowboat" as a pun on Asimov's I, Robot, in which an anthropomorphic Rowboat gives a speech parodying much of the angst experienced by robots in Asimov's fiction, including a statement of the "Three Laws of Rowboatics": A Rowboat may not immerse a human being or, through lack of flotation, allow a human to come to harm. A Rowboat must obey all commands and steering input given by its human owner, except where such input would conflict with the First Law. A Rowboat must preserve its own flotation as long as such preservation does not conflict with the First or Second Law. J. L. Patterson in an illustration to an article on Asimov in Damon Knight's In Search of Wonder (2nd ed., 1967) added the following Laws: "4. A robot must behave at science fiction conventions, as long as such behavior does not conflict with the first Three Laws. 5. A robot must sell like mad." The novel "Mirror Friend, Mirror Foe" by Robert Asprin and George Takei refers to the First Law as being included in any robot's programming. That is one of the few cases in fiction when the law is named fully (Asimov's First Law of Robotics). Lester del Rey refers to the laws as "The Three Laws of Asenion's Robots" in his 1966 short story "A Code for Sam." In the story, the laws found in old science fiction stories is used as the basis for an experimental code of ethics for robots. Terry Pratchett's early SF novel The Dark Side of the Sun (1976) gives a glimpse of the possible future development of the Laws: in one scene, a robot explains that it is permitted to use minimum necessary force against humans if directly ordered to do so, and cites the "Eleventh Law of Robotics, Clause C, As Amended". In a further nod to Asimov, the robot is named Isaac. In his later novel Going Postal (2004), the protagonist Moist von Lipwig, upon being told that he will be killed by a golem should he commit another crime, exclaims that that
