Prince Harry had the nation in stitches when he responded to Barack and Michelle Obama's Invictus Games video with an epic 'boom' drop. And now Harry has been served the same hilarious hand motion by Rio Woolf, a seven-year-old amputee.
Rio was making an appearance on Good Morning Britain, in which he spoke about his passion for the Paralympics. The youngster is about to jet off to Florida to meet his heroes – the wounded men and servicemen – who are taking part in Prince Harry's Invictus Games.
Charming viewers, Rio sent a message to the Prince, copying his famous 'boom' drop.

"Hi Harry," he said, waving to the cameras before dropping his hand. "BOOM!"
"Do it again, do it again," laughed presenters Susanna Reid and Ben Shephard.
"BOOM!" said Rio.
"That's all you need, we win," said Ben.

Rio, who lost his leg as a baby, explained that he loves playing amputee football and sitting volleyball. The Invictus Games athletes are his heroes.
Harry is in the US ahead of the Paralympic-style tournament, which kicks off on Sunday. The sporting event sees wounded servicemen and women from 15 nations compete in ten sports, including wheelchair rugby and wheelchair tennis.
Her Majesty laughed off the Obamas' antics with an exasperated "oh really, please!"
In anticipation of the event, Barack and Michelle Obama sent a hilarious Twitter video to Prince Harry, telling the royal to make sure Team GB "brings it".
Harry responded to the banter in the best way possible, by roping in his grandmother the Queen. The pair starred in a jokey video, showing Her Majesty responding to the Obamas' antics with an exasperated "oh really, please!" as Harry smirks at the camera.
"Boom!" he adds, throwing down his hand.
The Prince captioned the video: "Unfortunately for you @michelleobama and @barackobama I wasn't alone when you sent me that video – Prince Harry."
