Rome had traffic jams before cars were even invented. In this episode, Gordy reveals which city in history was the first to reach a population of one millionâand why the answer might surprise you.
Spoiler: It wasnât New York. Or London. It happened over 2,000 years ago in a marble-and-mud metropolis powered by aqueducts and political drama. After that ancient milestone, it took more than a thousand years for another city to hit the same mark.
Gordy breaks down the next big leaps: ⢠Changâan in the Tang Dynasty ⢠Baghdad during the Islamic Golden Age ⢠London by the 1800s ⢠New York during the Gilded Age ⢠Tokyo, which went from 10 million to 30 million faster than any city in history
Itâs the story of urban population explosionsâand how humans became really good at living shoulder to shoulder.

Why do we stash our savings inside a ceramic pig? Why not an owl? Or a vault? Or literally anything else?
In this episode, Gordy digs into the surprisingly strange history of the piggy bankâa financial icon born not from porcine symbolism, but from a Middle Ages typo. It turns out that âpiggyâ used to mean something very different⌠and one potterâs confusion changed the shape of savings forever.
Youâll learn:
What the word âpyggâ originally meant
Why breaking the bank was literally how you got your money back
And how a clay pun snowballed into a global pig-shaped tradition
So if youâve ever cracked open a piggy bank and wondered where this odd little ritual came fromâthis oneâs for you.
Stay curious. Stay clever. Welcome to the Smartest Year Ever.

The nuchal ligament is a weird little strap in the back of your neckâbut it might be one of the reasons humans became the sweatiest, slowest apex predators on Earth.
In this episode of Smartest Year Ever, Gordy explores why humans are built to run, and how a hidden ligament connecting your skull to your spine helps keep your head from bouncing like a bobblehead. This simple structure shows up in horses, dogs⌠and us. And it may have been crucial in the rise of persistence huntingâthe strategy our ancestors used to chase antelope to death.
Youâll also hear about:
⢠How the nuchal ligament acts like a biological Steadicam
⢠The fossil record that links it to Homo erectus
⢠Why evolution didnât prioritize speedâbut stamina
⢠What early anatomists got wrong about this tissue
So if your head isnât flopping while you jog⌠thank your neck.

After a rainstorm, you know exactly the smellâthat earthy, oddly comforting scent that makes you want to bottle the sidewalk. Itâs called petrichor, and today, Gordy breaks down whatâs actually causing it, why our noses are absurdly sensitive to it, and how it mightâve helped early humans survive.
From geosmin (a compound made by soil-dwelling bacteria) to the way raindrops launch micro-particles into the air, this episode dives into the biochemistry of nostalgia, plant oils, and even the camel's desert superpowers. Oh, and yesâsomeone did try to bottle it. His mom was not a fan.
Topics covered:
Why geosmin smells so strong (even in trillionths)
What âpetrichorâ actually means and who coined it
How raindrops work like confetti cannons for scent
Why we might be evolutionarily wired to love it
Whether you can bottle rain smell (spoiler: maybe donât)
So there you have itâpetrichor: the scent of bacteria, plants, and survival.

April is known for showers, fertility goddesses, and Easter eggsâbut how much of that reputation holds up? In todayâs episode, Gordy cracks open the surprisingly weird truth behind Aprilâs soggy rep, name origins, and ancient roots.
Youâll learn: ⢠Why April isnât actually the rainiest month in most places ⢠Where the phrase âApril showers bring May flowersâ comes from ⢠What Aphrodite, Venus, and Äostre have to do with April ⢠How Easter got its nameâand why most languages call it something else
From Roman love goddesses to springtime pagan festivals, April is messier than your weather appâand a whole lot older.

At 16 years old, Benjamin Franklin pulled off one of the greatest literary pranks in colonial Americaâhe catfished Boston as a snarky, opinionated widow named Mrs. Silence Dogood.
In todayâs episode, Gordy uncovers the wild true story behind the Silence Dogood letters, the essays that tricked Franklinâs brother, captivated readers, and launched Benâs obsession with fake names. From mocking the elite to receiving marriage proposals, Franklinâs teenage troll campaign helped launch his career.
Learn why Franklin:
Used a fake identity to get published
Wrote 14 letters as a fictional widow
Got his brother arrested and took over the paper
Spent his life writing under dozens of pseudonyms
If Franklin had Twitter, he'd have burner accountsâand still be roasting people anonymously.

Why do we prank people on April Foolsâ Day? And how did it get so weirdly universal? In this episode, Gordy untangles the strange, murky origins of one of the worldâs most chaotic non-holidays. From French calendar reforms to fake spaghetti trees and medieval mistranslations, this lighthearted deep dive is part history lesson, part conspiracy theory, and part cultural facepalm.
Find out:
Why some people think April Foolsâ Day began in 1582 France
How a bad translation of Chaucer may have fueled the confusion
What ancient Roman festivals like Hilaria have to do with it
And how the BBC convinced people that spaghetti grows on trees
Whether it started as a calendar mix-up or just human nature being messy, April Foolsâ is one tradition no one fully understandsâand that might be the most fitting prank of all.

Why does asparagus turn your bathroom break into a sulfur-scented science experiment? In todayâs episode, Gordy explores the bizarre phenomenon of asparagus peeâwhy it happens, why some people canât smell it, and why others canât stop smelling it. Spoiler: itâs not your imagination. It's sulfur chemistry and genetics at work. From asparagusic acid to a strange condition called asparagus anosmia, this episode dives into a stinky subject with surprising depthâand just the right amount of disgust.
Find out:
What chemical compound causes the smell
Why some people produce the smell while others donât
Why some people literally canât smell it, even if itâs there
And why cooking methods donât make any difference
Whether you're one of the lucky immune few or part of the cursed, once you learn this, youâll never look at asparagus the same way again.

Ever wonder why people say âPardon my Frenchâ after cussing? It has nothing to do with actual Frenchâand everything to do with irony.Originally, British and American elites used it to excuse real French words in conversationâbecause, you know, being bilingual is a flex. But then, people started using it sarcastically to excuse swearing instead. By the 20th century, it had nothing to do with actual Frenchâit was just a polite way to pretend you didnât just say something profane.đ Sources:

Most people think SOS means âSave Our Shipâ or âSave Our Souls.â It doesnât. In fact, it doesnât stand for anything at all.The famous SOS distress signal was chosen in 1908 simply because it was the easiest Morse code pattern to recognize:â⌠â â â âŚâ (dot dot dot, dash dash dash, dot dot dot)Over time, people made up meanings for SOS because they couldnât believe the most famous distress call in history was just a pattern of beeps.đ Sources:

What if I told you one of the most famous chess moves in history starts by giving away a pawn? Welcome to the Queenâs Gambitâone of the oldest and most effective openings ever played.
This strategy tricks opponents into thinking they have an advantageâbut itâs actually a power move that gives White control of the board. Itâs been played by grandmasters, world champions, and yes, even Beth Harmon in The Queenâs Gambit.

Why do Bird of Paradise plants look like actual birds? Is it just a coincidenceâor did nature design them that way on purpose?
Turns out, these plants evolved to mimic the shape of a birdâs head and beakâall to attract sunbirds, their perfect pollinators. When a sunbird lands on the flowerâs beak-like structure to drink nectar, the plantâs hidden pollen sacs pop open, dusting the birdâs headâhelping it spread pollen to the next flower.

Why do we say âP.U.â when something stinks? Itâs not short for anythingâso where did it come from?
Turns out, âP.U.â is actually a misheard version of an old exclamationââpyooââwhich came from the Latin word âputereâ (meaning âto stinkâ). Somewhere along the way, âpyooâ got written down as âP.U.â, and people assumed it stood for somethingâkind of like how people think âSOSâ means âSave Our Soulsâ (it doesnât).

You take a big sip of a milkshakeâand suddenly, it feels like your skull is being impaled by an icicle. Why does brain freeze happen?
It turns out, sphenopalatine ganglioneuralgia (yep, thatâs the real name) is just your body overreacting to extreme cold. When something icy touches the roof of your mouth, your blood vessels freak outâconstricting and then rapidly dilating. The trigeminal nerve, which senses pain in your face and mouth, gets confused and makes your brain think the pain is coming from your forehead instead.
đĄ Want to stop brain freeze? â Press your tongue against the roof of your mouth. â Drink lukewarm water. â Maybe donât inhale your Slurpee like itâs a race.
âď¸ Fun Brain Freeze Facts:
It happens faster in hot weather because your blood vessels are already dilated.
Migraines and brain freeze are weirdly connectedâif you get one, youâre more likely to get the other.
Scientists literally trigger brain freeze in labs to study headaches. Yikes.
So there you have itâbrain freeze is just your brain misinterpreting mouth pain as a cranial emergency. Next time it happens, just remember: youâre not dying, you just ate ice cream too fast.

On April 18, 1930, the BBCâs evening news came on air⌠and the announcer simply stated, âThere is no news today.â Instead of stretching for filler content, they just played 15 minutes of piano music and ended the broadcast.

Why do we call a butt a âheinieâ? Is it just a goofy word, or does it have a hidden connection to war and German soldiers?
There are two main theories behind this cheeky slang. The first is simple: it comes from "hind end", just like âtummyâ for stomach or âbootyâ for butt. But then thereâs the wartime theoryâduring World War I, Allied soldiers called German troops "Heinies" (short for Heinrich). Some etymologists believe that sayings like âkick their Heinieâ may have helped push the word into everyday slang.
So which is it? Most linguists think âhind endâ is the real source, but the war slang may have helped it spread. Either way, by the 1930s, it had lost any military meaning and was just a way to say âbuttâ without getting in trouble with your parents.
And if youâre into weird butt slang, here are two bonus facts:
âĄď¸ "Rump" originally meant the back end of a cow before humans claimed it for themselves.
âĄď¸ "Keister" comes from the German word for âsuitcaseââbecause someone, somewhere, thought a butt looked like luggage.
So there you have itâ"heinie" most likely came from âhind end,â but a little wartime slang may have given it a boost. Either way, itâs more fun to say than âgluteus maximus.â

đ§ Penguins are cute, right? Now imagine one standing 6â8â tall, weighing 250 pounds, and staring down at youâbecause these prehistoric penguins were the size of LeBron James.
Meet Palaeeudyptes klekowskii, the Colossus Penguinâan ancient giant that ruled Antarctica 37 million years ago. It was the tallest penguin species ever, towering over humans and twice the height of todayâs emperor penguins.
đ Why were these penguins so massive?
âď¸ Antarctica was warmer back then, with abundant food and no large marine predators
âď¸ Their size gave them a diving advantage, possibly staying underwater for up to 40 minutes
âď¸ They werenât aloneâmultiple species of giant penguins over 5 feet tall dominated prehistoric Antarctica
But then, seals and toothed whales evolved, bringing faster, more agile predators that outcompeted the Colossus Penguins, leading to their extinction.
So there you have itâbefore mammals ruled the oceans, giant penguins were the apex predators of the Southern Ocean.

đ Leprechaunsâtiny, mischievous, and obsessed with gold. But where did they actually come from? And why were they originally dressed in red?
Long before they were cereal mascots or St. Patrickâs Day icons, leprechauns were part of deep Irish mythologyâwith origins tied to the Tuatha DĂŠ Danann, a mystical race of supernatural beings. Their name comes from the Old Irish "luchorpĂĄn," meaning "small body," and the earliest known leprechaun story comes from an 8th-century Irish king who caught them dragging him into the sea.
This episode breaks down:
âď¸ The real origins of leprechauns and why they were once connected to shoemaking
âď¸ How they transformed from sea creatures into gold-hoarding tricksters
âď¸ Why they used to wear red coatsâand how marketing changed that forever
So there you have itâleprechauns started as supernatural shoemakers, wore red, and somehow became the official mascots of St. Patrickâs Day. And if youâre looking for a pot of gold? Maybe check behind the shoe rack.
