Prince Harry was forced to wear a German football scarf on national television after he took part in the country's version of Match of the Day but failed to score any points in a penalty shoot-out.
The Duke of Sussex is currently in Dusseldorf, Germany to support the bi-annual Invictus Games which he set up in 2014 to support wounded servicemen and women.
His appearance on Saturday night's show saw players attempting to score through small openings in opposing corners of a goal. To score a point, they had to accurately kick the ball through the target.
Harry cheekily asked: "What happens for zero?" with the crowd breaking into rapturous applause when presenter Sven Voss replied: "You have to wear a German jersey!"

The California-based royal missed six attempts to score a goal and was ultimately beaten by Germany's 63-year-old Minister of Defence Boris Pistorius - who only needed his first kick to beat the prince as he quickly netted two goals in a row.
As a forfeit, Harry was going to have to wear a German football jersey, but when one couldn't be found, the hosts of the show settled for the local club FSV Mainz's scarf for the Prince's punishment.
It comes after the Duke of Sussex flew by private helicopter from the opening ceremony of the Invictus Games to be a guest on the late-night TV show to help promote the Invictus Games.
He launched the bi-annual games on his own in Dusseldorf, Germany, as his wife Meghan remained home in California with their two young children, Prince Archie and Princess Lilibet. She is expected to join him later in the week and take part in the closing ceremony at the Merkur- Spiel Arena.
Earlier in the evening, Prince Harry had officially opened the games on stage in front of gathered dignitaries and competitors. He began his speech in German, welcoming everybody to the event, before he switched back to English and started talking about military uniform.
He said: "Remember that feeling of pride and honour when you first wore your nation's flag on your uniform? Most of us perhaps remember more its final outing? Or the time we hung it up for good?
"Am I right in saying for some, it represented a cape? Perhaps a shield or an escape? For others, an opportunity at recognition or a calling. No matter what it meant to you then, or your reasons for signing up, it was always about being of service to others and to your mates. Ultimately, you were part of a purpose bigger than yourself and that feeling felt good."
