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."
