Prince William revealed his daughter Princess Charlotte’s favourite joke “that she keeps telling me” on a visit to a school in the West Midlands today.
Asking the pupils to interact with him, the Prince of Wales proceeded to deliver a knock knock joke.
He said: “Knock knock”. “Who’s there?” the pupils asked.
“Interrupting cow”, William said. The pupils then started to reply “Interrupting cow, who?” – but the royal interjected with: “Moo!” prompting an eruption of laughter from the group of schoolchildren.
