This was the moment Barack Obama stunned members of the public when he turned up for jury service in Chicago.
The former US president was ultimately dismissed from jury duty at the Richard J. Daley Centre, but only after having caused a major commotion.
He was photographed outside by people who had read news reports that he had been summoned.
In the courthouse lobby, people craned their necks for a glimpse of him and took mobile phone pictures.
As Mr Obama arrived in the room, mobile phone footage recorded by another nominee, Angel Martinez, shows him smiling and raising a hand.
He asks: "How's everybody doing?" He then quickly tells the other nominees to “stay seated” as they begin to rise for him.
He adds: "Thanks to everybody for serving on the jury, or at least being willing to. This looks like Chicago right here, I like that!"
Mr Obama was not the first former president to be called for jury duty.
In 2015, former president George W. Bush answered the jury duty call in Dallas. He was not selected to sit on a jury.
In 2003, Mr Bush's predecessor in the White House, Bill Clinton, reported for jury duty in federal court in New York City. He also was not selected.
TV star Oprah Winfrey was on a Chicago jury that convicted a man of murder in 2004.
