Prince Philip, the 96-year-old husband of Britain's Queen Elizabeth II, is retiring from public engagements. Dubbed "Prince of Gaffes" by the British media, he himself noted his expertise in "dontopedalogy, the science of opening your mouth and putting your foot in it," CNN reported. Here are some of the moments that helped him earn the moniker.
During a royal visit to China in 1986, Philip described Beijing as "ghastly" and told British students: "If you stay here much longer you'll all be slitty-eyed." He also quipped: "If it has four legs and is not a chair, has wings and is not an aeroplane, or swims and is not a submarine, the Cantonese will eat it."
In 1995, Philip took up a British stereotype that Scots enjoy a drink or two, to ask a Scottish driving instructor: "How do you keep the natives off the booze long enough to pass the test?"
In 1996, he was interviewed on BBC radio as the UK government was about to ban ownership of handguns bigger than a .22 caliber. The measure followed the school massacre in Dunblane, Scotland, in which 16 children were killed. He expressed his sympathy to victims' families but questioned the planned restriction: "If a cricketer, for instance, suddenly decided to go into a school and batter a lot of people to death with a cricket bat, which he could do very easily ... I mean are you going to ban cricket bats?"
During a 1998 official visit to a British student who had been trekking in Papua New Guinea, Prince Philip (pictured here in 2007) asked: "You managed not to get eaten, then?" in an apparent reference to the historic belief that cannibalism had been practiced on the South Pacific islands.
In 2002, he shocked a Bangladeshi teenager at a London youth club by saying the 14-year-old "looks as if he is on drugs." Pictured: The Queen and the Duke wave goodbye at the Vancouver airport on Oct. 8, 2002.
The same year, Philip reportedly asked British Indian Labor MP Parmjit Dhanda -- a former student and trade union official -- what he did before becoming a politician, and then commenting: "So you didn't do anything then."

Also in 2002, he is reported to have asked Australian Aborigines: "Do you still throw spears at each other?" Pictured: The Duke attends the Royal Windsor Horse Show May 13, 2012.
In 2003, Queen Elizabeth II and Prince Philip went to open the Commonwealth Heads of Government Meeting (CHOGM) in Abuja, Nigeria. It was the Queen's first visit in 47 years. Greeted by Nigeria's then-President Olusegun Obasanjo, who was wearing traditional robes, Philip quipped: "You look like you're ready for bed."
In 2009, he told an Indian executive named Atul Patel: "There's a lot of your family here tonight," after seeing his name badge during a Buckingham Palace reception to honor 400 influential British Indians. Patel is a common surname in India.
Prince Philip's 90th birthday in 2011 prompted newspapers to match his years with an equivalent list of faux pas. Pictured: The Duke received ear defenders as a birthday present from the 'Action on Hearing Loss' charity, at a reception at Buckingham Palace on June 10, 2011, in London.
In the House of Commons, then-prime minister David Cameron (pictured at left) also paid tribute to the Prince as "a king among characters." "Humor is a great part of British life and we thank the Duke for his unique contribution."
