We just keep replaying his reaction.

Today, while in Melbourne, Prince Harry and Meghan Markle were invited to a reception at the Government House. While visiting, the royal pair were entertained by the "F1 in Schools" team who put on a toy car race display, even giving the Duke and Duchess of Sussex a chance to play. However, the hilarious moment came when the pair pushed the buttons to start the cars, which came as a serious surprise to Meghan as she was clearly unaware of how loud these toy cars would be. The loud bang caused Meghan to keel over laughing while Harry could not stop laughing, we think this moment might have made his day, Nothing like giving the missus a little shock, eh?

Prince Harry continued to joke that he thinks they should get one of these racing tables in Buckingham Palace even though, I'm not sure that would go down too well with Meghan. After that, Meghan and Harry dined at Charcoal Lane in Melbourne where they got to taste some local produce and delicious entrees. Yum. Their stay in Melbourne continues and the royal pair are set to head back to Sydney later on.
