President Donald Trump, his wife Melania and their son Barron hosted the White House's annual Easter Egg Roll over the weekend, and people can't keep their eyes off one particular moment.
In America, it's generally deemed etiquette to put your hand over your heart when the US national anthem plays. This is actually part of the United States 'Flag Code', which is not enforced by law but highly encouraged.
Unfortunately, Donald Trump forgot about this when 'The Star-Spangled Banner' played at the event, and Melania Trump gave him a little nudge to remind him.
And the Internet never forgets...
The event was nationally televised, so the moment has already gone viral, and there are some funny reactions that have emerged...
And we were just waiting for someone to point out the irony of Melania Trump noticing the error and Donald Trump's stance on immigration.
