Tigers are not female lions. Pickles are just cucumbers in vinegar, living their best fermented life. Reindeers aren’t mythical creatures, or Santa’s pets – they do actually exist.

These are things we generally should know by the time we reach adulthood. But some people missed the memo and ended up having hilarious lightbulb moments way too late in life. It doesn’t make them dumb. The internet has proven that even some of the smartest souls have at least one glaring gap in their knowledge. And many don’t discover it until someone looks at them like they still believe in Santa.

Someone asked, “What fact did you learn at an embarrassingly late age?” and thousands of answers came flooding in faster than Santa could come down the chimney. Some were hilarious cases of “lost in translation,” like a person thinking the Sistine Chapel was the “16th Chapel.” Others were more dramatic. Pure, unfiltered human cluelessness.

Bored Panda has put together a list of the funniest times people were humbled by common knowledge too late in life. We also share some facts that many people don’t know – yet. You’ll find those between the images.

The piggy going to market isn’t buying groceries

Edit: The first little piggy guess to market to be sold as meat.

The second piggy stays home as breeding stock.

The third piggy eats roast beef and other leftovers from the table to fatten him up.

The fourth piggy has none, as you usually don’t feed shortly before slaughter.

The fifth one didn’t sell, so it makes pig sounds (or cheers “Oui!”) All the way home.

BartlebyX:
I learned this a few days ago. I’m 44.

ChocolateSporks:
Omg.. Well I’m 22, I had to learn sometime. Now I’m sad. Why are nursery rhymes always so [messed] up when you actually get into the meaning of them..

I didn’t know pickles were just cucumbers in vinegar until I was 19.

greebshob:
I too didn’t learn this until I was around 25. Not only that, but I thought that pickles were used to pickle other things. I envisioned harvesting them from the pickle farm, juicing them, and then soaking other things in the juice to “pickle” them.

My dad had me convinced that Alice Cooper and Anderson Cooper were the same person and that “Alice” was his stage name before he became a reporter. Figured it out at 16…

I used to spell ‘put’ as ‘poot’ for the longest time…

I am not proud of this.

I’m not sure how I made it past elementary school let alone being a Computer Engineer.

I didn’t know narwhals were real until sophomore year of college. I knew what they were, but I thought that they were like a mermaid or a sphinx.

ramengirl10:
To be fair, sailors thought narwhals were mermaids.

I taught a friend in her 20s that reindeer are not mythical creatures. I told someone this story and I hear another 20 year old behind me whisper to a friend “are they actually real”.

This may seem too ridiculous to be true, but I assure you, it is…

Until she was in her mid-twenties, my sister believed Mount Rushmore was a naturally occurring rock formation. Until somewhere in her teen years, she thought earlier Americans had used Mount Rushmore to select presidents, and was very concerned we had “used up all the good ones.”

Lyeta:
During a finals week in college, one of my hall mates was reading something about philosophy and conspiracies or something and they for whatever reason it was talking about mt Rushmore. She comes out to where some of us are working at like 1am and goes ‘I think I’m just really tired, but this book just said mt Rushmore is a natural creation. That’s not right, right? It’s man made, right?’
Sleep deprivation+intellectual stimulation= brain rot.

That people are supposed to primarily breathe thru their nose? Finally went to doc today, nose is jacked up and there’s hardly an airway. I always just thought you were supposed to breathe thru your mouth and your nose is just a smeller. :(.

After watching a video of astronauts sleeping in space, I asked my husband why they didn’t just turn the artificial gravity on. He explained it’s not real, then pat my head. This was a few months ago, I’m 27.

Till i was in my early twenties, i thought duct tape was duck tape, used to tape ducks after going duck hunting.

anon:
It’s only called “duct tape” by virtue of people thinking “wait, ‘duck tape’ can’t be right, that sounds dumb it must be ‘duct tape'” and that’s become the actual name for it now.

But it was originally called duck tape and it’s certainly not meant primarily for use on ducts (even though I’m sure it is used on them by misinformed janitors).

Growing up I knew there was word spelled *rendezvous* that meant ‘to meet up with’ but I had no idea how it was pronounced. I also knew there was another word pronounced ‘ron-day-voo’ that meant ‘to meet up with’ but I had no idea how it was spelled.

I think I was in my twenties before I figured it out..

I didn’t learn that fireflies were real until I was 20. The only time I had ever come in contact with anything like a firefly was at DisneyLand. So, I really didn’t think they were real. When visiting friends in Illinois, they were quite keen to tease me

That the chipmunks (the cartoon series) didn’t sing original songs. Couldn’t fathom how the chipmunks kept putting out hit after hit.

I was around 21 when I realized it wasn’t “old tomatoes” but actually ultimatum.

2OQuestions:
Well, bad performers were pelted with rotten tomatoes, and people put in the stocks in old times were pelted with rotten tomatoes, so if someone is given ‘old tomatoes’ it means they did something wrong.

‘It’s me or the dog! I’m giving you old tomatoes!’

That makes sense in a way.

I didn’t know how many months were in a year until I was about 10. My parents flipped out when they found out, and trained me 80’s montage style with a calendar.

First time I saw chihuahua in print I had to look it up because I had no clue what it was. I was well into my 20s.

I’ve lived in the same neighborhoods since I was born (20+ years). It took a person that just moved here a week ago to point out the streets are alphabetically organized from north to south.

Hump_the_yeti:
I’ve lived in Las Vegas NV for the last 10 years… There is a street named Valle Verde here, and the next street, literally one block over is named Green Valley. I didn’t know they were the same names just in two languages until a Mexican buddy of mine came to visit and he just said it off-handedly while we were driving down the street one day.

That Cherries were actually a real fruit, I thought it was a candy. I am 29.

Kind of similar story- my sister thought spaghetti are plants, just like rice until she was 14.

That whole milk wasn’t 100% fat… 2% vs 1% always confused me because it seemed like such a minor difference in the scheme of things.
