In 2015, a time capsule from 1944 was found beneath the City Hall stairs in Lebanon, New Hampshire. Inside was a whiskey bottle with a humorous note: "Whoever finds this bottle may keep it. Sorry, there is no liquor in it, but I drank it all up."

The note was signed by Samuel Stevens, a former city surveyor. Along with the bottle were old newspapers and a penny, but Stevens’ decades-old joke stole the spotlight.

We begin with an unforgettable underdog story. At the 1980 Winter Olympics in Lake Placid , New York , the United States faced what many considered a leviathan in ice hockey history. Adding to the challenge, the American team was composed mostly of 21-year-olds, making it the youngest U.S. squad in Olympic history . Yet, against all odds, these determined players triumphed over a heavily favored opponent in what became known as the " Miracle on Ice ."

Even more impressively, Ali’s victory came against an undisputed and undefeated heavyweight champion, whom he knocked out in the eighth round.

As mentioned earlier, Michael Phelps' historic victories at the 2008 Beijing Olympics were unprecedented, and narrowing it down to just one of his competitors wouldn't do justice to the event.

Meanwhile, Serbian swimmer Milorad Čavić lost the 100m butterfly by an astonishing one-hundredth of a second —though he still managed to break the European record in the process.

The Big Apple: New York City

Everybody knows "The Big Apple" refers to New York— the city that never sleeps . But why, exactly? Is it because there’s a worm (the subway) underneath it? Or is it a metaphor for something we strive for?

The most populous city in Michigan, the nickname "Motor City" certainly feels right for its bustling streets and large industrial background —but what exactly led to the adoption of this powerful nickname?

Sin City: Las Vegas

We all know the famous adage: "What happens in Vegas, stays in Vegas." Given the city’s notorious nightlife and gambling scene , it’s understandable—you might prefer to forget how you lost all your savings on a slot machine. But is that the only reason it earned its infamous nickname?

The Windy City: Chicago

Situated on the shores of Lake Michigan, Chicago's nickname might seem to stem from its exposure to harsh weather —but sometimes, the obvious answer isn’t the correct one. Is it really the weather, or is something stranger at play?

The Mile High City: Denver

Image: Emmanuel Appiah

Is Denver really a "Mile High" city because of its geographical proximity to the towering Rockies, or is it just a nod to its ever-expanding skyline? Keep reading to find out!

And now, the answers:

7

The Big Apple: Horse-racing origins

Image: Taylor Sondgeroth

The nickname originated in the 1920s as horse-racing slang , where "The Big Apple" informally referred to New York’s prize racetracks. Jazz musicians later popularized it, and a 1970s tourism campaign ultimately cemented it as a symbol of the city’s cultural and financial prominence.

8

The Big Easy: Chill and jazz

Image: Robson Hatsukami Morgan

If you followed our line of thought—you were right! This nickname emerged from the city's reputation for its relaxed lifestyle and vibrant jazz scene . While there are many theories about who first used the term—and whether it was originally meant to be derogatory—one thing is certain: all New Orleanians agree it 100% reflects the city’s unique blend of music, culture, and laissez-faire attitude.

Motor City: Infinite assembly lines

Image: Austrian National Library

Detroit earned its nickname as the birthplace of the American auto industry. Henry Ford’s revolutionary assembly line and the rise of car manufacturing giants cemented the city’s status as the global automotive capital of the 20th century. In fact, it remains home to the headquarters of America’s largest auto manufacturers—General Motors, Ford, and Chrysler.

10

Sin City: Prohibition defiance

Image: Jakub Dziubak

For a city founded by religious missionaries, "Sin City" is certainly an ironic nickname. In truth, its origins trace back to the construction of the nearby Hoover Dam in the 1930s. Thousands of workers flocked to the city in search of lodging and—presumably—entertainment. This led to the rapid rise of casinos and a thriving underground alcohol industry that—during Prohibition—was as profitable as it was illegal.

11

The Windy City: Long-winded speeches

Image: Kristina Paparo

While many assume it refers to Chicago’s weather, the nickname was actually coined by journalists mocking the boastful speeches of local politicians as they aggressively promoted the city as the ideal location for the World’s Fair. The term was meant to highlight the "hot air" of their rhetoric rather than the city's literal windiness.

The Mile High City: A matter of altitude

Image: Bill Griepenstroh

Denver sits exactly 5,280 feet — one mile — above sea level , earning its nickname, the "Mile High City," quite literally. Its natural elevation, combined with stunning Rocky Mountain views, makes it truly unique. Even more interesting, Denver’s altitude leads to some unusual effects: golf balls can travel up to 10% farther than at sea level, and alcohol tends to hit harder since high altitudes reduce the body's ability to process it efficiently.
