Laughing matter: The Clintons relax at an official function

Independent counsel Kenneth Starr's 445-page document lists 10 sexual encounters between the president and the former White House volunteer Monica Lewinsky.
In his efforts to hide the affair, Bill Clinton "pursued a strategy of deceiving the American people and Congress" for seven months, the report adds.
Mr Starr alleges perjury, obstruction of justice, interfering with witnesses and abuse of presidential power.
He made no comment about the report but, flanked by his wife Hilary, told his audience that he had "work to do".
But as Capitol Hill's decision makers took the damning report home to scrutinise its contents, President Clinton's lawyer David Kendall went on the offensive, describing the dossier as "personal and not impeachable."
"No amount of gratuitous allegations about his relationship with Ms Lewinsky can alter the fact that he did not commit perjury, he did not obstruct justice, he did not tamper with witnesses and he did not abuse his powers of office."
'Lies under oath'
In the damning opening to his report Mr Starr alleges that Mr Clinton lied under oath to the grand jury to hide the truth about his affair.
It alleges that the president did have a sexual relationship with Ms Lewinsky, even under the definition of a sexual relationship given by his own lawyers, contradicting his earlier testimony.
Mr Starr's lists nine instances of oral sex and alleges that on one occasion Mr Clinton and Miss Lewinsky had oral sex while the president spoke on the telephone to congressmen.
It goes on to reveal that DNA tests carried out by the FBI almost indisputably proved that semen found on one of Ms Lewinsky's dresses matched a sample provided by the president.
Summing up, Mr Starr writes: "Perjury and acts that obstruct justice are profoundly serious matters.
"When such acts are committed by the president of the United States, we believe those acts may constitute grounds for an impeachment."
The report's publication on US Government Websites caused a huge increase in Internet traffic as users around the world attempted to access the report.
After initial jams, the report was republished on mirror sites around the world, including at the BBC, in what many have hailed as a triumph for the medium.
Although the US House of Representatives voted overwhelmingly to publish the report, the task of deciding what to do with it now falls on the Judiciary Committee.
Its members may decide to hold their own hearings and have the power to begin impeachment hearings in the US Congress.
