Talk about bro shade! The professor of the class told Harry that they wouldn't tell William what he had said, to which he replied, "He knows it!”
The royal younger brother did get knocked down a peg, however, when none of the students knew who he was! After responding with silence when asked if they knew who was visiting them, Harry responded, "That's the right answer!"
Kensington Palace posted photos of Harry's trip to Instagram, writing, "Some of the boys who are supported by Ottery Youth Centre #CapeTown shared their experiences with Prince Harry today."
The palace captioned another pic, "Prince Harry joins the coaches in a practical football and life skills sessions on the pitch, including, on the eve of #worldaidsday, a SKILLZ for HIV awareness activity at the Football for Hope Centre."
Meanwhile, it seems almost impossible to knock the "cool younger brother" off his high horse, even when he literally falls off of a horse. Watch the prince recover with all his royal charisma intact in the video below.
