Background: Legion (David Charles Haller) is a fictional superhero appearing in American comic books published by Marvel Comics. He is the mutant son of Professor Charles Xavier and Gabrielle Haller. Legion takes the role of an antihero who has a severe mental illness including a form of dissociative identity disorder, in which each of his alternate personas controls one of his many superpowers. The television series Legion premiered on FX network in 2017.
Context: When Mystique tracked down David years later to get revenge for "his" murder of Destiny, he awakened with his fractured mind healed. David had a new goal, to help his father realize his dream of human-mutant coexistence by killing Magneto, Xavier's greatest opponent, before he had a chance to amass power. He traveled twenty years into the past, when Xavier and Magneto were orderlies at the mental hospital. In the process, he loses his memory. Magneto then accidentally triggers his memory, causing David to go on a rampage, attacking Magneto and revealing the existence of mutants to the public decades too early. Several X-Men who were pulled back in time with him were unable to prevent him from attacking Magneto. Xavier, however, leaped into the path of the psi-knife (the focused totality of Legion's psionic powers) and was killed in Magneto's place, causing the formation of the Age of Apocalypse timeline.  Due to being trapped in the past by David's actions, Bishop enlisted the aid of the new reality's X-Men to travel back in time to confront Legion again. Bishop seized Legion's psi-blade and drove it into his own chest, allowing Legion to see the future that he caused. In his last moments, David apologized for what he did. David's mother, Gabrielle Haller, described having a "maternal loss" afterward, implying she miscarried before giving birth to David.  While David was considered deceased, some of his alternate personalities remained trapped between life and death, manifesting as spirits. When the spirits started terrorizing Israel, Excalibur was called to stop them. After learning that the spirits were refusing death, Meggan used her empathy to calm their rage, convincing them to go "towards the light."
Question: What is significant about these two things?
Answer: When the spirits started terrorizing Israel, Excalibur was called to stop them.

Background: Clinton Richard Dawkins  (born 26 March 1941) is an English ethologist, evolutionary biologist, and author. He is an emeritus fellow of New College, Oxford, and was the University of Oxford's Professor for Public Understanding of Science from 1995 until 2008. Dawkins first came to prominence with his 1976 book The Selfish Gene, which popularised the gene-centred view of evolution and introduced the term, meme. With his book The Extended Phenotype (1982), he introduced into evolutionary biology the influential concept that the phenotypic effects of a gene are not necessarily limited to an organism's body, but can stretch far into the environment.
Context: In his book, The Selfish Gene, Dawkins coined the word meme (the behavioural equivalent of a gene) as a way to encourage readers to think about how Darwinian principles might be extended beyond the realm of genes. It was intended as an extension of his "replicators" argument, but it took on a life of its own in the hands of other authors, such as Daniel Dennett and Susan Blackmore. These popularisations then led to the emergence of memetics, a field from which Dawkins has distanced himself.  Dawkins's meme refers to any cultural entity that an observer might consider a replicator of a certain idea or set of ideas. He hypothesised that people could view many cultural entities as capable of such replication, generally through communication and contact with humans, who have evolved as efficient (although not perfect) copiers of information and behaviour. Because memes are not always copied perfectly, they might become refined, combined, or otherwise modified with other ideas; this results in new memes, which may themselves prove more or less efficient replicators than their predecessors, thus providing a framework for a hypothesis of cultural evolution based on memes, a notion that is analogous to the theory of biological evolution based on genes.  Although Dawkins invented the term meme, he has not claimed that the idea was entirely novel, and there have been other expressions for similar ideas in the past. For instance, John Laurent has suggested that the term may have derived from the work of the little-known German biologist Richard Semon. In 1904, Semon published Die Mneme (which appeared in English in 1924 as The Mneme). This book discusses the cultural transmission of experiences, with insights parallel to those of Dawkins. Laurent also found the term, mneme, used in Maurice Maeterlinck's The Life of the White Ant (1926), and has highlighted the similarities to Dawkins's concept. James Gleick describes Dawkins's concept of the meme as "his most famous memorable invention, far more influential than his selfish genes or his later proselytising against religiosity".
Question: why not?
Answer: John Laurent has suggested that the term may have derived from the work of the little-known German biologist Richard Semon.

Background: Rowan & Martin's Laugh-In (often simply referred to as Laugh-In) is an American sketch comedy television program that ran for 140 episodes from January 22, 1968, to March 12, 1973, on the NBC television network. It was hosted by comedians Dan Rowan and Dick Martin. Laugh-In originally aired as a one-time special on September 9, 1967, and was such a success that it was brought back as a series, replacing The Man from U.N.C.L.E. on Mondays at 8 pm (ET). The title of the show was a play on the "love-ins" or "be-ins" of the 1960s hippie culture, terms that were, in turn, derived from "sit-ins", common in protests associated with civil rights and antiwar demonstrations of the time.
Context: The first season featured some of the first music videos seen on network TV, with cast members appearing in films set to the music of the Nitty Gritty Dirt Band, the Bee Gees, the Temptations, the Strawberry Alarm Clock, and the First Edition.  During the September 16, 1968, episode, Richard Nixon, running for president, appeared for a few seconds with a disbelieving vocal inflection, asking "Sock it to me?" Nixon was not doused or assaulted. An invitation was extended to Nixon's opponent, Vice President Hubert Humphrey, but he declined. According to George Schlatter, the show's creator, "Humphrey later said that not doing it may have cost him the election", and "[Nixon] said the rest of his life that appearing on Laugh-In is what got him elected. And I believe that. And I've had to live with that." In an episode of the ill-fated 1977 revival, a Nixon impersonator says "I invited the American people to sock-it-to-me.... you can stop now".  On multiple occasions, producer George Schlatter attempted to get William F. Buckley Jr. to appear on the show, only to be refused each time until he suddenly agreed to an appearance. In the episode that aired December 28, 1970, Buckley appeared in an unusual sit-down segment (portions of which were scattered throughout the episode) flanked by Rowan and Martin and fielding questions from the cast (which included Lily Tomlin doing her Fast Talker shtick) and giving humorous answers to each. Near the end, when Rowan asked Buckley why he finally agreed to appear on the show, Buckley explained that Schlatter had written him "an irresistable letter" in which he promised to fly Buckley out to California "in an airplane with two right wings". At the end, Rowan thanked him for appearing, noting that "you can't be that smart without having a sense of humor, and you have a delightful one".
