🍀 Leprechauns—tiny, 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. Patrick’s Day icons, leprechauns were part of deep Irish mythology—with origins tied to the Tuatha Dé Danann, a mystical race of supernatural beings. Their name comes from the Old Irish "luchorpán," 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:

✔️ The real origins of leprechauns and why they were once connected to shoemaking

✔️ How they transformed from sea creatures into gold-hoarding tricksters

✔️ Why they used to wear red coats—and how marketing changed that forever

So there you have it—leprechauns started as supernatural shoemakers, wore red, and somehow became the official mascots of St. Patrick’s Day. And if you’re looking for a pot of gold? Maybe check behind the shoe rack.

What’s the steepest street in the world? You might think of San Francisco, but the true king of inclines is Baldwin Street in Dunedin, New Zealand—and it has the Guinness World Record to prove it… after a heated battle.

Baldwin Street’s brutal 34.8% gradient means a casual walk can feel like a mountaineering expedition. But this record didn’t stay unchallenged—in 2019, a street in Wales briefly stole the title, setting off an international steepest-street showdown.

This episode breaks down:

✔️ How 19th-century British city planners accidentally created a nightmare incline

✔️ The Guinness World Record controversy and how New Zealand fought back

✔️ The wild events people do on Baldwin Street—including racing and rolling chocolate candies down the hill

So there you have it—a record-breaking hill, a world title dispute, and an incline so absurd even locals were hoping Wales would take the crown.

Think St. Patrick’s Day is all about wearing green, drinking Guinness, and pretending you know what a shamrock is? Well… not exactly.Turns out, St. Patrick wasn’t even Irish, Ireland never had snakes, blue was the original color, and pubs in Ireland were actually CLOSED on St. Patrick’s Day until the 1970s. So how did this solemn religious feast turn into an excuse to drink like a medieval monk? Irish-Americans, that’s how.Gordy breaks down the real history of St. Patrick’s Day, the myths that people still believe, and how an enslaved teenager became the patron saint of Ireland.

Why is alcohol measured in "proof"? And what exactly are we proving? Turns out, the answer is equal parts history, science, and good old-fashioned fire.

Back in the days of the British Royal Navy, sailors had a unique way of making sure their daily rum rations weren’t watered down—by lighting them on fire. If the rum-soaked gunpowder still ignited, that was "proof" it hadn’t been diluted. The magic number? 57.15% alcohol by volume—which became the definition of 100 proof. If it didn’t light, someone was cutting corners, and a mutiny might be brewing.

This fiery test wasn’t just for sailors—tax collectors and distillers also used it before more precise measuring tools existed. The U.S. eventually adopted a simpler system (just double the ABV), but England stuck with their old method until 1980.

So why do we still call it “proof” today? Some traditions just refuse to sink.

Snake venom… as medicine? That’s right. Modern blood pressure drugs exist because of a deadly pit viper. Scientists discovered that the venom of the jararaca pit viper caused instant drops in blood pressure, making people collapse on the spot. Instead of running away, they studied the venom—and turned it into ACE inhibitors, one of the most widely prescribed heart medications today. From a snake bite to a life-saving drug, this is the wild story of how medicine turns nature’s most dangerous tricks into our best cures.

Ever wonder why people say "the proof is in the pudding"? Proof of what? And why pudding? Was there some kind of medieval pudding trial we all forgot about?

Turns out, the original phrase actually made sense—but over time, English speakers did what they do best: butchered it beyond recognition.

The original saying was "the proof of the pudding is in the eating," first recorded in the early 1600s. Back then, "proof" meant "test," not "evidence" like in a courtroom. And "pudding" wasn’t a sweet dessert—it was a medieval meat dish, often stuffed with spices, grains, and... questionable chunks of animal parts. Some were delicious. Others? Potentially deadly.

The only way to know if a pudding was safe to eat was, well… to eat it. Thus, “the proof of the pudding is in the eating.” Eventually, the phrase got misheard, shortened, and turned into a modern idiom that makes no sense at all.

So there you have it—a medieval food safety warning turned into an everyday saying, proving that sometimes, history’s biggest test is simply surviving bad translations.
