Problem: Background: Dr. Victor Von Doom (commonly known as Doctor Doom, or simply Doom) is a fictional character appearing in American comic books published by Marvel Comics. The son of a Romani witch, Von Doom has been depicted as a supervillain, the archenemy of the Fantastic Four, and the leader of the fictional nation called Latveria. While his chief opponents have been the Fantastic Four, he has also come into conflict with Spider-Man, Iron Man, Black Panther, and multiple others. Von Doom has also been depicted as a superhero, being the third character to take up the mantle of Iron Man and joining the Avengers.
Context: In 1976, Marvel and DC Comics collaborated on Superman vs. the Amazing Spider-Man, and seeking to replicate that success the two companies again teamed the characters in Superman and Spider-Man in 1981. Marvel editor in chief Jim Shooter co-wrote the story with Marv Wolfman, and recalled choosing Victor von Doom based on his iconic status: "I figured I needed the heaviest-duty bad guy we had to offer -- Doctor Doom. Their greatest hero against our greatest villain."  The same year, John Byrne began his six-year run writing and illustrating Fantastic Four, sparking a "second golden age" for the title but also attempting to "turn the clock back [...] get back and see fresh what it was that made the book great at its inception." Doctor Doom made his first appearance under Byrne's tenure with issue #236. Whereas Kirby had intimated that Doom's disfigurement was more a figment of Victor's vain personality, Byrne decided that Doom's face was truly ravaged: only Doom's own robot slaves are allowed to see the monarch without his helmet. Byrne emphasized other aspects of Doom's personality; despite his ruthless nature, Victor von Doom is a man of honor. Returning to Latveria after being temporarily deposed, Doctor Doom abandons a scheme to wrest mystical secrets from Doctor Strange in order to oversee his land's reconstruction. Despite a tempestuous temper, Doom occasionally shows warmth and empathy to others; he tries to free his mother from Mephisto and treats Kristoff Vernard like his own son. Byrne gave further detail regarding Doom's scarring: Byrne introduced the idea that the accident at Empire State University only left Victor with a small scar that was exaggerated into a more disfiguring accident by Doom's own arrogance--by donning his newly forged face mask before it had fully cooled, he caused massive irreparable damage.  After Byrne's departure Doom continued to be a major villain in Fantastic Four, and as the 1980s continued Doom appeared in other comics such as Punisher, The Spectacular Spider-Man, and Excalibur. Under Fantastic Four writer Steven Englehart, Doom became exiled from Latveria by his heir Kristoff, who was brainwashed into thinking he was Victor von Doom. Doom would spend most of his time in exile planning his return, but Englehart left the title before he could resolve the storyline. This storyline ultimately ended with the controversial Fantastic Four #350, where writer Walt Simonson had the Victor von Doom who had been seen in the book during the Englehart run being revealed to be a robotic imposter and the real Von Doom, in a newly redesigned armor, returning to claim his country from his usurper. According to Simonson's retcon, the last appearance of the real Victor von Doom was in the "Battle of the Baxter Building" story arc, but Simonson's interpretation of the character was unaware of certain major changes at the time to the Fantastic Four. Simonson drew up a list of stories which featured the real Doom and those which did not but later writers ignored Simonson's choices, retconning these story elements as an attempt by Doom to blame his own past failures on unruly robots.
Question: WHich other comics did Doom appear in?
Answer: Punisher, The Spectacular Spider-Man, and Excalibur.

Problem: 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 1970-71 season brought new additions to the cast include tall, lanky, sad-eyed Dennis Allen, who alternately played quietly zany characters and straight man for anybody's jokes; comic actress Ann Elder, who also contributed to scripts, tap dancer Barbara Sharma, and Johnny Brown.  Arte Johnson, who created many memorable characters, insisted on star billing, apart from the rest of the cast. The producer mollified him, but had announcer Gary Owens read Johnson's credit as a separate sentence: "Starring Dan Rowan and Dick Martin! And Arte Johnson! With Ruth Buzzi ..." This maneuver gave Johnson star billing, but made it sound like he was still part of the ensemble cast. Johnson left the show after the 1970-71 season. Henry Gibson also departed after the 1970-71 season. Johnson and he were replaced by former Hogan's Heroes stars Richard Dawson and Larry Hovis, both of whom had appeared occasionally in the first season. However, the loss of Johnson's many popular characters caused ratings to drop further.  After winning the Academy Award for Best Supporting Actress in Cactus Flower, Goldie Hawn made a guest appearance in the third episode of the fourth season. She began the episode as an arrogant snob of an actress; however, a bucket of water thrown at her transformed her back to her giggling dumb blonde persona.  The show celebrated its 100th episode during the 1971-72 season, with Carne, Worley, Johnson, Gibson, Graves, and Tiny Tim all returning for the festivities. John Wayne was on hand for his first cameo appearance since 1968.
Question: what happened in the 5th season?
Answer:
the loss of Johnson's many popular characters caused ratings to drop further.
