See Prince William's Reaction to a Cheeky Man's Candid Comment About Kate Middleton: 'Your Wife's Not Bad'

The Prince of Wales visited a new cancer research and treatment center, where he met a patient who couldn't hide his sense of humor

Prince William just met a patient who gave Kate Middleton his seal of approval.

The Prince of Wales, 40, stepped out on Thursday to open the Oak Cancer Centre at the Royal Marsden, a new cancer research and treatment center. During the visit, William met a man who has been treated there and his wife.

The man didn't hide his sense of humor, telling Prince William, "You're a tall bugger, in't you?" immediately after shaking his hand, as seen in a video shared by The Royal Family Channel.

"I have heels on," William quipped in response.

As she spoke with the royal, the woman praised the U.K.'s National Health Service (NHS) for taking care of her husband for 10 years. He then chimed in, "See these people here? Ugly but they're good," prompting a laugh from Prince William.

The woman then praised the new facilities — but the man turned the conversation to the Princess of Wales. "And your wife's not bad," he said. "She's a nice lady."

Prince William laughed and said, "He's a chatty one. The nurses have got their eye on you."

This isn't the first time that someone has told Prince William that they are a fan of Princess Kate, 41. While meeting well-wishers in 2020 during their visit to Ireland, Angela Moran told PEOPLE about her encounter with the royal.

“I said to him that I really admired him and Catherine, and he said, 'Thank you very much,' " she said. “I said, 'I love her,' and he said, ‘I do too — nice of you to say so.' "

Prince William's visit to the new cancer care center was part of his role as president of The Royal Marsden, a title previously held by his mother, Princess Diana.

Nearly three years ago, the royal laid the foundation stone for the Oak Cancer Centre.
