Ever the good sport, Harry gamely took part and revealed his preferences, from red wine over white to crisps over peanuts.
But when it came to answering who he liked more out of national treasures Ant and Dec, the Prince showed a little more hesitation.

"Ant or Dec? This is the killer," said chat show host Chris.
"Together, please," said Harry.
"No, not allowed," said Chris.
"Really? But I've been in the middle, in between the two of them," replied Harry. After some hesitation, the Queen's grandson replied: "Ok, uh... Ant."
"Really?" asked Chris.
"Yeah, sorry Dec!" laughed Harry.
Harry and William have met Ant and Dec several times in the past
During the amusing live interview Harry, 31, also tried his hand at radio presenting and delivered some of the morning's "breaking news". The Prince, who was joined by 2016 UK Invictus Games Team Captain David Wisemann, began by greeting Chris with "Good morning ginge!" before reading the news.
"Breaking news, left nostril has finally unblocked after six weeks. Rachel in South Wales," said Harry, laughing at the jokey headlines. "Breaking news, I'm going to cut the grass today for the first time this year, Roger!" he carried on.
Fans were quick to praise the royal for his entertaining appearance on the show – although Harry did have a more serious subject to talk about. The Prince and his friend David were promoting the forthcoming 2016 Invictus Games, which will take place in May in Orlando, Florida.

The Paralympic-style tournament will see 500 competitors – wounded servicemen and women – from 15 nations compete in ten sports, including wheelchair rugby and sitting volleyball.
"This is about supporting the local heroes, the local guys," said Harry. "Find out who your local guy is, find out if he's in the Invictus team and support him."
"The power of sport is something unbelievably special," he added.
