Several members of the Royal Family have been known to play pranks on one another over the years. While Queen Elizabeth II once tricked American tourists in Balmoral, Princess Diana reportedly had a "really filthy" sense of humor. According to a former royal butler, Prince William has also been known to "play pranks" on wife Kate Middleton. In fact, royal staff apparently helped the Prince of Wales carry out one particular joke involving a black cat.
Former royal butler Grant Harrold reflected on William and Kate's humorous relationship, telling Heart Bingo, "They do love playing pranks. When you say play pranks, it's more jokey; it's silly things they do to each other."
