Prince William and Kate Middleton met when they were students at the University of St. Andrews in Scotland, and while the Princess of Wales famously caught her now husband's attention when she wore a risqué, transparent dress to a school fashion show, her sense of humor was a look the future king It turns out that it was another trait.

“William once described Kate's sense of humor as ‘naughty’ and his own as ‘dirty,’ and claimed it was one of the most important things that brought them together,” Christopher Andersen, author of The King, told Fox News.

Apparently, they have also passed on their comedic skills to Prince George (age 11), Princess Charlotte (age 9), and Prince Louis (age 6).

Prince William confirmed the children's screen-time battles at a recent BAFTA event in London, telling onlookers that George, Charlotte, and Louis “are always wrestling over the remote control.” Royal children... . are just like us.

Andersen also noted that Welsh children inherited their parents' strong competitive spirit. The royal writer told Fox News, “The Prince and Princess of Wales have competed in foot races, swimming races, board games, card games, everything.”
