Prince William was meeting pupils at a school when he revealed the joke

The Prince of Wales was visiting a school in the West Midlands when he shared the joke.

Prince William was invited to the school by a 12-year-old pupil last October.

The pupil, Freddie, had asked the prince to visit the school to learn how pupils are being supported with their mental wellbeing.

Freddie told the prince he had written to him for his help getting the message out that it was okay for people to express their emotions.

The royal then greeted school staff before sitting down and sharing "dad jokes" with pupils for a mental health podcast.

"I've been asked to produce a dad joke," the prince said.

He then made the pupils laugh by telling daughter Princess Charlotte's favourite gag.
