[Q]: Question: What war were the boats like Kennedy was on used in? Passage:Within weeks, many Americans could recite favorite lines from the record, including "the rubber schwan [swan] is mine", and "move ahead...with great vigah [vigor]", the latter lampooning the President's own words. The album poked fun at Kennedy's PT-109 history; the rocking chairs he used for his painful back; the Kennedy clan's well-known athleticism, football games and family togetherness; children in the White House; and Jackie Kennedy's soft-spoken nature and her redecoration of the White House; and many other bits of knowledge that the public was eager to consume. Kennedy himself was said to have given copies of the albums as Christmas gifts, and once greeted a Democratic National Committee group by saying, "Vaughn Meader was busy tonight, so I came myself." According to UPI reporter Merriman Smith, during a Cabinet meeting Kennedy played the entire record for everyone. At one press conference, Kennedy was asked if the album had produced "annoyment (sic) or enjoyment." He jokingly responded, "I listened to Mr. Meader's record and, frankly, I thought it sounded more like Teddy than it did me. So, now he's annoyed."

[Q]: Question: When was the author of JFK and the Unspeakable born? Passage:Jim Garrison said anti-Communist and anti-Castro extremists in the CIA plotted the assassination of Kennedy to maintain tension with the Soviet Union and Cuba, and to prevent a United States withdrawal from Vietnam. James Douglass wrote in JFK and the Unspeakable that the CIA, acting upon the orders of conspirators with the "military industrial complex", killed Kennedy and in the process set up Lee Harvey Oswald as a patsy. Like Garrison, Douglass stated that Kennedy was killed because he was turning away from the Cold War and pursuing paths of nuclear disarmament, rapprochement with Fidel Castro, and withdrawal from the war in Vietnam. Mark Lane — author of Rush to Judgment and Plausible Denial and the attorney who defended Liberty Lobby against a defamation suit brought by former CIA agent E. Howard Hunt — has been described as a leading proponent of the theory that the CIA was responsible for the assassination of Kennedy. Others who believe the CIA was involved include authors Anthony Summers and John M. Newman.
