Britain's Prince Harry calls Queen Elizabeth "granny".
The young royal - who is currently on a tour of New Zealand - took questions from school children during a trip to Stewart Island, with one youngster asking how he refers to his grandmother.
He revealed: "I call her Granny, but I refer to her as the Queen because I'm in the army and she's my boss."
The 30-year-old prince also took other peculiar questions from the 24 children at Halfmoon Bay School - located 30 kilometres south of South Island - including what his favourite meal is.
He replied: "Spaghetti Bolognese. Is that a good answer?"
However, other kids were more interested in his profession as a military helicopter pilot, with one child questioning him on what his favourite thing about the job is.
He answered: "You have a moving office... There's only two of you in the office and no one else can bother you."
Elsewhere during his stay in New Zealand, the prince has enjoyed a pub quiz trivia night, and also come face to face with a 118-year-old reptile.
The prince met the endemic creature - who is coincidentally named Henry, Harry's birth name - at Invercargill Airport, as he continued his journey to Stewart Island.
