Philip (91), famed for his off-the-cuff remarks, apparently made the hospital worker from the Philippines laugh with his comment during a visit to open a cardiac centre.
BBC Online reported the Duke as saying to the unnamed woman: “The Philippines must be half-empty — you're all here running the NHS.”
Philip's remark came during a visit to Luton and Dunstable University Hospital, where he officially launched the multimillion-pound cardiac centre.
Philip had a stent fitted to clear a blockage in a coronary artery in December 2011 and when, during the visit, he was given a gold-plated stent, he quipped that he now had a spare.
The Duke is well-known for his outspoken comments and famously told British students during a 1986 state visit to China: “If you stay here much longer, you'll all be slitty-eyed.”
