Prince Harry and renowned primatologist Jane Goodall met at an event on Tuesday. Instead of shaking hands, however, the Duke of Sussex patted Ms Goodall on the head in what is known as a 'chimpanzee greeting'.
A video of the charming greeting that delighted onlookers was shared online by Sussex Royal - the official Instagram account of Prince Harry and Meghan.
The video shows the 85-year-old conservationist instructing Prince Harry to pat her head before they hug. According to the caption, Ms Goodall taught Prince Harry the greeting when they first met.
"The pair share an impromptu dance and 'Chimpanzee Greeting' which Jane taught The Duke when they first met," wrote Sussex Royal while sharing the video on Wednesday.
