is impossible, because everyone knows "a golem mustn't harm a human being or allow a human being to come to harm". However, he is informed that the rule continues "... unless ordered to do so by duly constituted authority." Roland Charles Wagner wrote a short story, Three Laws of Robotic Sexuality (1982), which treated the use of robots for sexual pleasure. John Sladek's parodic short story "Broot Force" (supposedly written by "I-Click As-I-Move") concerns a group of Asimov-style robots whose actions are constrained by the "Three Laws of Robish", which are "coincidentally" identical to Asimov's laws. The robots in Sladek's story all manage to find logical loopholes in the Three Laws, usually with bloody results. Sladek later wrote a novel, Tik-Tok (1983), in which a robot discovers that his so-called "asimov circuits" are not restraining his behavior at all, making him in effect a sociopath; he comes to doubt whether "asimov circuits" are even technically possible, deciding that they are simply a pseudo-religious belief held by robots. Sladek also made use of the Three Laws in his satirical sci-fi novel Roderick (1980), where the first self-aware robot on earth is constantly met with patronizing disbelief that he actually is a robot, and is schooled as a normal, albeit "schizophrenic" human child. The school priest, harboring a knack for philosophical sci-fi, tries to "cure" Roderick of his "dillusion" of being a robot by having him read Asimov. Roderick responds by verbosely pointing out the various logical inconsistencies in the Three Laws and Asimov's overall work, and ultimately drives the priest insane. Lyuben Dilov introduced a Fourth Law in his novel Icarus's Way (original title: Пътят на Икар): "A robot must always reveal itself as a robot." Nikola Kesarovski introduced a Fifth Law in his short story "The Fifth Law" (original title: Петият закон): "A robot must know it is a robot". In the novel, the Fifth Law originated as a result of a murder: a humaniform robot, itself not knowing the fact it was a robot, embraced a human being so strongly that the human's ribcage was crushed, resulting in the human's death. In other words, the robot did not know and could not measure its own physical strength. Similarly, in David Langford's Lensmen parody Sex Pirates of the Blood Asteroid, reprinted in He Do the Time Police in Different Voices, the protagonist met a "Vomisa" robot who had "not been
