Prince Philip turned 98 on June 10, but his sense of humor never fades. His witty remarks and jokes continue to amaze everyone, and in fact he often makes it to the headlines for his hilarious comments, which also make Queen Elizabeth giggle every time.

The Queen once paid tribute to the “Duke of Jokes” through her Christmas message two years ago. She praised his unique sense of humor, which she said is one of the secrets why their marriage lasted for so long. Here is a list of Prince Philip’s funniest quips and headline-grabbing jokes through the years.

1. Prince Philip’s China Visit

When the Duke of Edinburgh visited China in 1980, he described Beijing as “ghastly” and told the British students that they would be “slitty-eyed” if they will stay there longer.

2. Pirate Comment On His Cayman Island Trip

Prince Philip flew to the Cayman Islands for an official trip in 1994 and met the locals. At one point, he met an islander and his humor surfaced again. “Aren't most of you descended from pirates?” he asked the local. 

3. The Royal Etiquette

The 98-year-old royalty expressed his opinion on etiquette. In particular, he shared some wise quote that can potentially upset Queen Elizabeth. “When a man opens a car door for his wife, it’s either a new car or a new wife,” he once said.

4. Meeting Dr. Robinson In Australia

Prince Philip and the Queen attended an event in an Australian university, and the royal couple was introduced to Mr. Robinson and his wife. The duke noticed that Mr. Robinson’s wife is a Ph.D. and realized that her title is more important than his, so he said something funny when she was introduced to him. “Ah, yes, we have that trouble in our family too,” the prince remarked. 

5. A Joke On Scottish Driving Test

In 1995, while in Scotland, the prince met a driving instructor. “How do you keep the natives off the booze long enough to pass the test?” he asked

6. Not A Fan Of Celebrities

Prince Philip has famous funny lines involving celebrities, and he does not care if they are world famous or not. “Oh it's you that owns that ghastly car is it? We often see it when driving to Windsor Castle,” he told Elton John.

In an event in 2002, he heard that Madonna is set to perform the theme song of “Die Another Day” and he seemed to hate the idea. “Are we going to need earplugs?” he asked. 

Cate Blanchett met Prince Philip, and as they exchange some pleasantries, he casually asked her if she could repair his DVD player because she “worked in the film industry.”

It appears that the duke is not fond of Tom Jones when after watching his performance in 1969 he gave his honest opinion. “What do you gargle with, pebbles?” he asked the singer.

The prince also remarked later that he can't understand why Jones is popular. “It's hard to see how he is popular as he sings the most hideous songs,” Prince Philip commented. 

Prince Philip’s goal is to make strangers laugh within the first 15 seconds after introduction. Apparently, he always succeeds.
