You may know her as Queen Elizabeth II. Queen. Her Majesty the Queen, Her Ladyship, Her Royal Highness. Even Lilibet. But Gary?

Yes, the Queen's nickname was Gary. Thanks to a little boy named Prince William.

Today is Mother's Day in America. Let's learn why the patriarch of the British royal family is called by such a strange nickname in the family. He stumbled and asked his grandmother for help, but she didn't say "grandmother." Instead?

"Gary!"

...... The Mirror reported, "Much to the consternation of everyone present."

Everyone started looking for Gary nearby. A guest who went to help asked who Gary was," as reported by the Mirror, and the Daily Mail speculated that he was a member of the royal family.

"I'm Gary." The Queen was morose as she hurried to comfort her grandson. She said, "He hasn't learned to say 'grandma' yet.

"Gary" then thankfully evolved into "Granny" from her grandchildren; at the 2012 Olympics, when the Queen opened the London Games with a fantastic performance with Daniel Craig as James Bond, William and Harry both shouted "Go Granny!" in unison and were called "Gan Gan" by their great-grandchildren, like Prince George, according to the Duchess of Cambridge in 2016. (Fun fact: "Gan Gan" is also what Prince Charles, Prince William, and Prince Harry called their respective great-grandmothers.)

And William, not to be outdone, has had several nicknames over the years. William's wife, Kate, hilariously calls him "Baldy" and "Big Willie"; in 1983, his mother, Princess Diana, called him "Wombat."

"It started when I was two years old," William said. 'When I went to Australia with my parents, they started calling me that, not because I looked like a wombat, because wombats were the local animal there. It might have been."

These are pretty good nicknames, but few in royal folklore go beyond Gary.
