Question: Jefferson doesn't know who the vice president was during Eisenhower's presidency. Why does this convince Al that Jefferson is a real American?
Answer: Although the vice presidency is the second-highest U.S. office, it is also a relatively non-powerful one. Few VPs were notable or distinctive while in office, and most are forgotten once their term ended unless they later assumed the presidency, such as Teddy Roosevelt, Richard Nixon, and Lyndon Johnson. A few VPs who became president, such as Andrew Johnson, Chester A. Arthur, John Tyler, and Millard Fillmore, are barely remembered for holding either office.
Answer: The joke being that Americans don't know their own history, whereas foreigners do. When applying for US citizenship (naturalization), non-exempt applicants have to take a civics test that tests the person's knowledge of US government and history.
