Where is my chair? Bizarre moment Jill covers her mouth as Joe suddenly bends down during the 80th anniversary D-Day speech

You might want to sit down for this. 

President Joe Biden briefly squatted down during ceremonies commemorating the 80th anniversary of D-Day, the corrected himself while other dignitaries remained standing for his defense secretary.

The odd moment came during an interlude after Biden and French President Emmanuel Macron greeted surviving heroes of the Normandy invasion, as a military band played somber music.

Biden, 81, then bended his knees as if he were preparing to sit down.

Just as he was preparing to plop down, the music suddenly cut, and a loudspeaker told the gathered 'distinguished guests' that Defense Secretary Lloyd Austin would speak. 

That got Biden to pause halfway to the chair. He then slightly elevated himself as if to stand. Then, he got the message and lowered himself down as other standing notables did the same.

Biden may have gotten some covert stage directions from first lady Jill Biden, who was standing next to him, and who sometimes IDs the exits during his public events.

 After Biden starting squatting down, the first lady covered her mouth and scratched the area above her upper lip. It was impossible to tell whether she let him know it wasn't yet the declared time to sit.

Biden, who regularly addresses crowds who must wait for his security and arrival, regularly tells his own listeners to take a seat if they have one.

The unusual moment came during a day of moving encounters with some of the last members of the 'Greatest Generation.'

Biden met with two dozen U.S. vets who landed at Normandy in 1944 and served in what he called a 'crusade' that ultimately liberated Europe from Nazi tyranny. 

With several thousand vets and servicemen and women in the crowd, along with dignitaries that included Macron and French first lady Brigitte Macron, Biden may have been approximating an old military saying: 'Never stand when you can sit, never sit when you can lay down, never lay down when you can sleep.'

The president may have dabbed at his eyes a few times, and clenched his fist following a flyover.

The solemn ceremony, amid a time of other brutality that the president referenced in his speech, had a few other light moments, such when vet Robert Gibson, 11, told Biden, 'Don't get old.'

Jill Biden appeared eager to keep things moving. After the conclusion of the event, she guided Biden off the stage. The couple departed after Biden shook hands with a few more vets, holding hands as they walked. Macron remained behind to greet more of them.
