Really, is there any combination of Olympic sport and spectator that seemed more of a given than Prince Harry at the women's beach volleyball final?
Good thing he didn't disappoint us, then, as the royal who isn't on the receiving end of Justin Bieber's hairism was spotted in the stands of the matchup between Brazil and China, which took place just before the much-anticipated (and, incidentally, all-American) matchup between Misty May-Treanor and Kerri Jennings Walsh, and Jen Kessy and April Ross.
As Prince William is back to the business of being an RAF pilot this week, he did not luck out in joining his brother for the game, though that doesn't mean Harry was without some cheering accompaniment.
Joining the young royal in the stands were Team GB's Olympic cyclists Jason Kenny and Laura Trott, who were, judging by the numerous photos of the laughing prince, charming.
As it happens, Harry has long proclaimed himself a fan of the sport, ever since he got in on a volley while in Rio earlier this year.
Meanwhile, Harry's trip to the Horse Guards Parade stadium also gave the world a new contender for cutest photo to emerge from the London games.
The unwitting entrants: the prince and British rower Constantine Louloudis, who in addition to his newly won gold medal must also be in possession of one of the most distractingly comfortable shoulders in the U.K.
Look alive, boys. There's a game afoot.
