No amount of protocol and formal events are going to curb the humor of the British royal family. Here are some of the most hilarious quotes that show that royals like to let loose too!

1. “[Kate’s cooking] is the reason I’m so skinny.”

Kate Middleton admitted that she is not the best cook, and Prince William, well, wholeheartedly agreed!

2. “William had to do his hair!”

The duchess  got to hit back, though, explaining one time that they were late to an event because the prince took a bit too long to get ready. He had to make sure his hair looked good.

3. “He's old. She's pregnant.”

Prince Harry wouldn't miss a chance to mess with the Duke and Duchess of Cambridge. When asked at the 2012 London Marathon about why Prince William and Kate weren't at the event, he responded as cheekily as one would expect him to be.

4. “I think he definitely is brainier than I am, but we established that at school … along with his baldness.”

Clearly, Harry especially likes to pick on his older brother. As siblings would, the two would take a shot at each other whenever possible. After Harry jokes about Prince William's hair or more accurately the lack of it, his big brother hit back, “That’s pretty rich coming from a ginger!”

5. “The prince was interested in the alpaca, and as I showed it to them, the princess said he should put it on his head. She said, ‘You need it more than me,’ and pointed to his head and he laughed.”

The royal family definitely has no shortage of hair jokes for the duke. While recalling a recent trip, Kate did not pass up the opportunity for another one.

6. “[Prince George] got way more hair than me, thank God!”

It's always great to be able to laugh at oneself. William embraced the hairline jokes with a punchline of his own during Prince George's first public appearance.

7. “As I learned from growing up, you don't mess with your grandmother.”

Prince William knew early that his grandmother isn't to be trifled with. Her Majesty is the longest-running monarch who has as much control on all of various nations and governments as she has with swans and his brother's facial hair. So yes, he's got that right!

8. “I hope it arrives soon because I'm going on a holiday.”

The Queen doesn't wait for anyone, apparently even for her great-grandson. Her Majesty jokingly said she would prefer it if Kate's son came out before she jets off for a vacation.

9. “It's also great that you can give your grandchildren back to their parents anytime.”

After gushing about how happy he is to be a first-time granddad, Prince Charles still couldn't help but keep it real (and hilarious) when talking about the reality of royal babies.

10. “I myself prefer my New Zealand eggs for breakfast.”

After protesters threw eggs at her during a visit, the Queen looked at the brighter side of the situation.

11. “When a man opens a car door for his wife, it’s either a new car or a new wife.”

There's no better way to wrap up a list of all the funniest quotes by the British royal family without this gem by Prince Philip, who had to teach people that not everything is what it seems.
