The Queen is known for having a sense of humour, often finding times to make light of a situation.
On one occasion, when she discovered a dead slug on her dinner plate, she responded in the best way.
The Queen's former servant, Charles Oliver, recalled the incident and how she reacted in his book 'Dinner at Buckingham Palace', reports MyLondon.
Oliver revealed that when the Queen and her late husband Prince Philip would eat together, they would keep a notepad next to their plates so they could make notes about the meal and give their feedback to the chef.
"Once, on a torn-off top sheet the footmen found the dead body of a slug," Oliver said.

On the note, the Queen had written: "I found this in the salad—could you eat it?"
She then sent the plate of food and the note back to the kitchen, the Daily Mail's Weekend magazine reports.
One of the chefs, Darren McGrady, says the Queen chooses all of the food that she eats off of specific menus from the kitchen.
Darren explained: "The chef does three days’ menus and that gives us enough time to get all the produce in and prepare it.
"When the menu book goes up to the Queen she puts a line through all the dishes she doesn’t want.
"If she’s out for dinner she’ll put a line through the page.
"And if she has a guest coming she’ll put two or three, so we know she is entertaining,” Darren said.
He also revealed that she hates pasta, garlic and onion, but she loves to eat chicken or fish with vegetables or salad.
The food she does like, on the other hand, is kept under lock and key as she has never revealed them, not even to the staff in the kitchen.
Former royal correspondent Gordon Rayner, who has covered more than 20 royal tours, discovered this fact from someone who worked with the royal family.
He explained to The Express : "As one of her staff told me, 'If she said she had a favourite meal she would never get served anything else.'"
Before she's due to travel for royal duties, someone from the team will also go on a ‘reconnaissance’ mission to make sure it's up to standard, and if not, to make any necessary tweaks.
"The Master of the Household department will be in the reconnaissance party to tell foreign chefs not to cook anything with garlic or too much spice for fear of giving the Queen bad breath, and not to cook shellfish or anything that could cause food poisoning," he added.
