Prince Philip has dropped another clanger while on a Jubilee visit with his wife in Kent.
Spotting an attractive young woman in the waving crowd, the frisky 91-year-old royal turned to the policeman standing next to her and gestured towards her tight red dress which had a zip running the length of its front.
"I would get arrested if I unzipped that dress!" the prince said.
The woman, Hannah Jackson, retained her composure as the police officer fell about in fits of laughter.
Friends of the 25-year-old Bromley Council worker told The Daily Mail in London that Prince Philip was merely trying to put the young blonde at ease.
"It was one of Prince Philip's classics," an onlooker told The Daily Mail. "I saw that he made a passing remark to the police officer who was trying to contain his laughter, so I asked him what was so funny.
"The policeman was standing in a council line-up along with this girl looking pretty in a red dress and I had to ask him exactly what he'd said because he was laughing so much.
"He told me the Duke had said: 'I would get arrested if I unzipped that dress'."
Accompanying the Queen as her Diamond Jubilee Tour, Prince Philip and the Queen were welcomed by more than 6000 flag-waving school children.
A Council staff member told The Daily Mail that Ms Jackson was amazed at the public reaction to the Prince's comments.
"She's had to take the afternoon off because she wouldn't get any work done here anyway," she said.
Hannah's mother-in-law, Angela Jackson, appeared taken aback at the fuss over the prince's comments.
The Prince has become well know for his gaffes over the years.
In 1986 he told British students in Beijing: "If you stay here much longer you'll all be slitty-eyed."
On an Edinburgh factory tour in 1999 he remarked that a fuse box "looked as though it had been put in by an Indian".
In Wales recently he told a group of teenagers from the British Deaf Association who were standing near a loud Caribbean steel band: "If you're near that music it's no wonder you're deaf."
Even the Philip's family weren't protected from his sarcasm. A few years ago he said of daughter, Princess Anne: "If it doesn't fart or eat hay, she is not interested."
