Have you ever found yourself in a conversation, when someone brings up a topic they aren't too familiar with, but you are?

This gives you the opportunity to sweep in and share your knowledge on the subject.

While one would imagine that your relative expertise on the subject might result in thanks and appreciation, more often than not, the reaction from your friends is "why do you know that?"

Awkward as it may feel at the moment, there are very few people who don't carry some unusual areas of expertise and trivia on subjects most others are most likely unfamiliar with.

Redditor quadruple_b was curious to learn the random facts others have shared which wound up bringing their conversations to a halt, leading them to ask:

What is a really weird fact, that makes people say "why do you know that?"

Octopuses... they're just like us

"Octopuses are usually very antisocial but when they’re under the influence of ecstasy they are more willing to spend time around each other or even hug other octopuses."- Stab_That_Ukulele

The body compensates

"When you are starving, and have little body fat left, your body can grow almost fur-like hair to insulate itself in absence of fat."- A_Stupid_Fish29

"Your body’s normal functions can slow down to accommodate organ disease."

"For example, I have 40% lung function, but my O2 is completely normal at 98% saturation."

"They didn’t discover any lung disease until I had a ct scan done for other reasons and my lungs happened to show up in that."- nocturnal_numbness

What this would do for humanity!

"Cheetahs are so genetically similar that supposedly you can draw blood from one and inject it straight into another one without any health issues in the receiving animal."

"I.E. no blood type or clotting factor variations."- 0ttr

"In Phoenix, Arizona, you are legally allowed to bury a dead body on your property without asking for permission/getting a permit/etc."

Who wouldn't?

The brain is a delicate creature

"There is a chemical called MPTP that specifically destroys dopaminergic neurons in the brain."

"About 3 days after someone ingests it, they get Parkinson's disease."- SheilaBoof

Gruesome with good intentions?

"In the 1960s or 70s, the Swiss Air Force dropped severed chicken heads all over the forests of Switzerland."

"The chicken heads contained the rabies vaccine, and the airdrop was to vaccinate wild foxes against rabies."- EnormousPurpleGarden

Makes you think twice about randomly plotted plants...

"If you bury a body, cover it with endangered plants so no one digs it up."- milkmankarl

This is why you don't play with your food

"Mayonnaise is flammable, and ketchup can be made into bombs."-- EGG_EGG_EGG_EGGG

I guess it's OK if it's in his own time?...

'My doctor at the GP is know in my town for violently masturbating between patients."

"It’s just something everyone knows but just ignores and accepts."- Waltz2496

Laying false claims!

"The dodo wasn’t hunted by the Dutch."

"It was by animals brought by the Dutch."

They're watching us...

"The NSA has a secret HQ in the middle of downtown NYC."

"They built it inside of a creepy skyscraper less than a mile from the World Trade Center.'

"Check out this video for more info."- Affectionate-Can-224

In case you wonder why it's taking so long...

'Most scaffolding in NYC isn't meant for construction."

"It's just sitting there to fulfill an inspection requirement."- Affectionate-Can-224

They were also often confused for sea serpents...

'A whales penis is 8 feet long or meters, can’t remember."- BenefitImpressive205

You have to wonder how he found that out?...

"Not mine, but Formula 1 driver Valterri Bottas knows that average penis size of a beaver to the mm."- tm2007

Let's hope these aren't related...

"So a pack of pirahnas can devour a child in under 5 minutes."

' Anyways, I was fired from the Aqarium yesterday."- MioncB

Ain't that a trip...

"A woman named Margaret Howe Lovatt had a sexual encounter with a dolphin during NASA-funded research in the '60s after the dolphine was dosed with LSD."- johnslegers

One never knows when learning this newfound information might become useful.

Especially for parents of children eager to buy a Guinea Pig...

People Describe The Real Reason They Cut Ties With Their Best Friend

Friendships are one the most important and intimate connections young people make. Friends are the people you are close to, who you grow up with, and who are always there for you when you need them.

However, not all friendships are meant to last. Sometimes, one or both of you will change. Other times, you'll just drift apart. And sometimes, the friendship will end because of malicious actions. Redditors seem to have a lot of those stories!

Indeed, some people have used social media to such an effect, that they are as or more well known than any number of movie stars.

But others might have put something on the internet just for fun, unaware that they had a viral sensation on their hands ("Charlie bit my finger" anyone?).

Some people soak in this unexpected fame for a moment or two, and then let it pass as they go on with their lives.

Others, however, might enjoy being unexpectedly famous, and will relish in their unexpected celebrity for the rest of their lives.
