Prince Andrew has humiliated Queen Elizabeth II several times throughout his life. Most recently, he admitted to disappointing his mother over his continued friendship with Jeffrey Epstein.

During his interview with BBC’s “ Prince Andrew & The Epstein Scandal,” the Duke of York said that what he did was very unbecoming of a member of the royal family.

“ Because it was not something that was becoming of a member of the Royal Family and we try and uphold the highest standards and practices and I let the side down, simple as that,” he said.

However, this wasn’t the only time that Sarah Ferguson’s ex-husband humiliated the 93-year-old monarch. In the book “My Husband and I: The Inside Story of 70 Years of the Royal Marriage,” royal author Ingrid Seward revealed how a young Prince Andrew suffered the wrath of the Windsor Castle staff.

The mischievous third child of the Queen and the Duke of Edinburgh became upset when no one paid attention to him that he started lashing out. While hanging out at the royal stables, Prince Andrew reportedly taunted the guardsmen and aimed sly kicks at the dogs.

“No one took any notice, so Andrew doubled his efforts and beat the ground even harder, taking a sideways swipe at the legs of horses. When he refused to stop, two grooms picked him up, threw him into the dung heap and shoveled manure all over him,” she said.

Prince Andrew was reportedly so shocked after the incident that he wasn’t even able to cry. However, this still didn’t stop him from humiliating the Queen.

During his visit to the set of “West Wing,” Prince Andrew was presented with a photo of Her Majesty, and he failed to recognize who she was. And just over two decades ago, Prince Andrew once again disappointed the monarch when his marriage ended in divorce.

But despite all of these blunders, the Duke of York still remains to be the Queen’s favorite child.
