On Tuesday, Prince William traveled to London’s Kensington neighborhood to show off his skills at a distinctly American pastime. During an event with the NFL Foundation UK, he grabbed a football and took a lesson in throwing it like a quarterback. At a flag football day celebrating the third anniversary of the football league’s community outreach across the pond, one participant gave him a football with a Union Jack, and in response he shared that he would use it to play with his children, Prince George, Princess Charlotte, and Prince Louis.

“Never go home empty handed! That’s a crucial motto of being a parent,” he said. “We’ll do some practice together—let’s see how many windows I can smash.”

For the first decade of their marriage, Prince William and Kate Middleton reportedly had permission from Queen Elizabeth II to focus on bringing up their three children, so they have plenty of good parenting tips. Though their roles as working royals have sent them around the world and take up plenty of their time, they’ve arranged their schedules so they are able to consistently take their children to school in the morning and even host a few of their children’s friends for palace playdates.

During the Tuesday event, William also spoke to Phoebe Schecter, Great Britian’s women’s flag football captain, and according to the AP, she gave him a pointer on throwing the ball: embrace your “inner Shakira” and shake your hips. Following their playtime, Louis Rees-Zammit gave him a teal Jacksonville Jaguars jersey with “HRH” emblazoned on the back.

Rees-Zammit, a 23-year-old from Penarth, Wales, played professional rugby football in the UK before taking part in the NFL’s International Players Pipeline Program earlier this year. Following an initial signing to the roster of the Kansas City Chiefs, he joined the Jaguars’ practice squad as a running back in August. Rees-Zammit later told People that William was interested in hearing about his journey from the UK to America. “He was intrigued about the transition I’m doing and the sport itself,” the athlete said. “He asked me what I could bring from rugby into the NFL, like my speed.”
