Prince William's humor was on full display on Christmas Day, as he entertained the audience at Sandringham with his contagious sense of humour.
The Prince of Wales talked with well-wishers along the route to the church, and in one especially humorous moment, his children and the audience burst out laughing.
A video circulating on social media showed the future King busting up at a dog sitting in a pram, which elicited chuckles from Prince George and Princess Charlotte as they shared the delight with their father.
When he noticed the unexpected sight, he commented, "Look at that doggy! "Are they in a pram?" Before mocking the owner, "Have you hijacked someone else's pram, or is that your dog's pram?"
Meanwhile, Kate, still recuperating from cancer, stole the show with her charm.
As she stood behind the family, speaking with well-wishers and taking flowers and chocolates, she said, "I think I've lost my family!" When she observed her husband and children waiting ahead, the audience laughed.
