Prince Philip is easily Britain's most blundering royal, but he's certainly not the only member of the monarchy to make a public blooper. To mark the Duke of Edinburgh's 90th birthday, TIME takes a look at some of the royal family's biggest gaffesPrince Charles Holds the Press in Contempt

In 2005, more than 50 journalists gathered at Klosters, a Swiss ski resort, for a photo call marking Prince Charles' imminent wedding to Camilla Parker Bowles. During the shoot, Charles couldn't hide his contempt. "I hate doing this ... I hate these people," he muttered to his sons Harry and William, unaware that his microphone was picking up every word. Asked by the BBC's royal correspondent Nicholas Witchell how he felt about his upcoming nuptials, Charles responded sarcastically, "I'm very glad you've heard of it, anyway." He then turned his head slightly toward Harry and whispered, "Bloody people. I can't bear that man. He's so awful, he really is."
Princess Anne Insults a Fan

On Christmas Day 2000, 75-year-old pensioner Mary Halfpenny spent three hours making a flower display for the Queen Mother, then waited patiently outside a church on Sandringham Estate - one of the royal family's country homes - hoping to present it to her. The exchange never happened. Instead, Princess Anne, Queen Elizabeth II's only daughter, grabbed the bouquet and huffed, "What a ridiculous thing to do!" The incident left Halfpenny reeling. "It was a really hurtful thing to say," she told reporters. "I've made baskets of flowers for the Queen, and she has always said how nice they are." And Anne's un-princesslike attitude didn't end there: she reportedly told her nieces, princesses Beatrice and Eugenie, to "get a move on" and discouraged them from accepting flowers from well-wishers.
