McCain, who turns 72 on Friday, had jokes like, "My social security number is eight" and "You forgot to mention that I warned the people about the British coming." When Leno asked, "For $1 million, how many houses do you have?" McCain brought up his five years as a POW in Vietnam, "I didn't have a house. I didn't have a kitchen table. I didn't have a table," and said of his wealthy wife, "I’m very proud of Cindy’s father. ... He made the American dream."
