Legal drinking age

Image: Elevate

When was the first time you tried a beer? Probably at 21 or later. While that's completely normal here in the US, it can seem a bit strange to people in other parts of the world. Why? In America, you can vote, serve on a jury, and even get married in some states at 18, but you still can't legally buy alcohol until you're 21. In many other countries, the legal drinking age is 18—or even younger—and that's why they find our law unusual.

The faces of real estate agents

We're used to walking through a neighborhood and seeing signs with real estate agents' faces in front of homes for sale. But in other countries, that's pretty unusual! In many places, real estate transactions are more impersonal; you deal with an agency, not a specific person. Here in the US, we like to put a face to the name. Getting to know the person helping you buy or sell a home feels more personal and trustworthy. It makes sense, right?

Our coins

Many of us don't even notice this until we travel abroad, but some of our coins don't actually show their value! Sure, you'll see words like "Five Cents," "One Cent," or even "One Dime," but there's no actual number printed on them. When you think about it, that's kind of strange, right? Especially when most countries display the value on their coins using numbers.

American flag everywhere

Image: camera obscura

In many countries, their national flag is used only for formal or official purposes, but that's not the case in the US. We tend to see the American flag literally everywhere, not just at official functions or holiday celebrations, but also on all kinds of products and imagery. From T-shirts and caps to food packaging and even swimsuits, our flag is a constant presence in everyday life.

No bad words on TV

If you're in America and turn on your TV right now, you'll find everything from romantic scenes to shows about zombies or violent crimes, but you'll rarely hear any bad language. Our television generally doesn't include insults or swear words, while in other countries they often do, even in shows that air during times when children might be watching.

Dinner before 8 PM

Depending on the region, dinner in the United States is often served before 8 p.m., and sometimes even before 7 p.m. But in many other countries, that's considered too early. In Latin America, for example, most people eat dinner between 8 and 11 p.m.!

The Imperial System

We Americans use miles, feet, pounds, and degrees Fahrenheit, but this is often very confusing for visitors from other parts of the world. We are totally used to the Imperial System, but in most countries, the Metric System reigns supreme, with everything measured in meters, kilometers, kilograms, and degrees Celsius.

Big portions

Large portions are deeply ingrained in our daily lives. Whether it's restaurant meals, snack packs, or soft drinks, everything tends to be bigger in America. This can be surprising for foreigners who come here and order food, since in many other countries, dishes are smaller, and the custom of taking leftovers home after eating at a restaurant isn't as common as it is in the US.

Turkey pardon

The pardoning of the turkey by the US president is a big event for many Americans. But in other parts of the world, where Thanksgiving isn't celebrated, it can come as a surprise. To foreigners, this formal ceremony involving a turkey might seem quite strange. Since Thanksgiving traditions aren't part of their history, this custom is uniquely American.

Alumni homecoming

Perhaps you've had the chance to participate in Homecoming, the annual event that celebrates university spirit with parties, sports games, and other activities for students returning to campus. While it's a big part of our college tradition and communities are deeply involved, it's quite different in other parts of the world, where the return to school usually happens with little fanfare.

1

The Pig War (1859)

A boundary dispute on San Juan Island nearly escalated into a U.S.-British war after an American farmer shot a British-owned pig that was rooting in his garden . Troops rushed in, tensions rose, and both sides came to the verge of open conflict.

Thankfully, the "war" ended without a single human casualty. Diplomacy prevailed, leaving history with a famously absurd standoff where the only fatality was the unfortunate hog that started it all.

2

The Toledo War (1835-36)

Believe it or not, Michigan and Ohio once squared off over a slim strip of land containing the city of Toledo . Militias mobilized, tempers flared, and political rhetoric soared past anything that the dispute really deserved.

The conflict produced only one injury: a sheriff was stabbed with a pocket knife. It ended with Michigan receiving the Upper Peninsula as compensation.

3

The Aroostook War (1838-39)

A mix of lumberjacks, militias, and confused officials sparked a border showdown between Maine and British Canada. Though the name sounds dramatic, the "war" consisted mostly of shouting, arrests, and paperwork .

Still, it lasted less than a year and recorded no combat deaths. Its odd blend of frontier folklore and diplomatic missteps gave it a reputation as one of America’s most harmless "wars."

4

Battle of Lake Erie (1813)

In a fierce naval engagement that lasted only a few hours, Commodore Oliver Hazard Perry secured control of Lake Erie during the War of 1812 . His quick, decisive victory shifted momentum in the northern theater of the war.

The battle is remembered for its speed and for Perry’s bold message: "We have met the enemy, and they are ours."

5

Battle of Blair Mountain (1921)

For five tense days in West Virginia, thousands of coal miners armed themselves against hired gunmen, local law enforcement, and eventually federal troops . It became the largest labor uprising in U.S. history.

Despite its scale, the conflict ended quickly once the Army intervened. Its strange blend of union struggle, machine guns, and biplanes made it one of the most dramatic yet short-lived labor battles ever fought.

6

Battle of Athens, Tennessee (1946)

World War II veterans took matters into their own hands and clashed with a corrupt county political machine after years of election wrongdoing. In a single night of gunfire and sieges, the veterans seized the jail and exposed the fraud .

By morning, order was restored and democracy reclaimed. The brief uprising became a legendary example of ordinary Americans pushing back against local tyranny.

7

Shelling of Fort Stevens (1942)

During World War II, a Japanese submarine surfaced off the Oregon coast and fired on Fort Stevens for roughly fifteen minutes . The startled gunners held their fire to avoid revealing their positions.

No lives were lost, and damage was minimal. Still, the brief attack stands out as one of the only direct assaults on the U.S. mainland during the war.

8

Battle of Palmito Ranch (1865)

Fought in Texas weeks after the Confederacy had effectively collapsed, this short skirmish featured U.S. and Confederate troops battling despite the war’s official end . Confusion and poor communication kept the fighting alive.

The engagement lasted only a few hours but became the Civil War’s final battle. Its odd timing makes it a historical footnote with a bizarre twist.

9

Battle of Ambos Nogales (1918)

A border misunderstanding escalated into a sudden firefight between U.S. and Mexican troops in the twin towns of Nogales, Arizona, and Nogales, Sonora. The shooting lasted only a few hours but drew civilians into chaos.

The brief clash prompted both governments to rethink border security. It remains the only World War I-era battle fought on U.S. soil involving foreign troops .

10

The Great Locomotive Chase (1862)

Union raiders stole a Confederate locomotive and sparked a dramatic pursuit through northern Georgia. The "battle" unfolded across railroad tracks and small towns over the course of a few hours.

Though unconventional, it was officially a military operation and became legendary for its daring and scope. The episode showed how even a train theft could become an act of war.

11

Little Belt Affair (1811)

This brief naval encounter between USS President and HMS Little Belt lasted less than an hour. Confusion over signals led to sudden gunfire and heavy damage to the British vessel.

The brief clash worsened tensions between the two nations and helped push the U.S. and Britain toward the War of 1812.

Beware of the banana peel!

It might sound like a scene straight out of The Three Stooges , but we assure you, this was once a legitimate concern. It’s no myth that residents of Waco, Texas are forbidden from eating bananas and tossing the peels into the street. Lawmakers feared horses could slip on the peels and injure themselves.

This is also true for Elmira, New York. A city ordinance from 1899 stated that no person could throw any banana peels—or any other fruit skins—onto the sidewalk. As it happens, back when bananas were introduced to the northern states, they were very cheap and people usually bought them in bulk. The surplus was huge and the waste was becoming a problem. In fact, in 1893 a woman sued the city after slipping on a banana peel, falling on the sidewalk, and breaking her leg.

Dueling candidates

It may sound old-fashioned, but this law is still in effect in West Virginia. To be eligible as governor, a candidate must not only be at least 30 years old and have resided in the state for at least five years preceding the election, but they must also never have participated in a duel.

According to §6-5-7 of the West Virginia Code, any citizen who sends or accepts a challenge or participates in a duel with deadly weapons "shall ever thereafter be incapable of holding any office of honor, trust or profit in this state." By the end of the American Civil War dueling had become almost obsolete, but for some reason, The Mountain State is one of the few states that still hasn’t repealed its dueling laws.

Extraterrestrial exposure

Despite popular opinion, Title 14, Section 1211 of the Code of Federal Regulations did not make it illegal for Americans to have contact with extraterrestrials or their vehicles. Instead, the law was enacted just before the Apollo 11 mission to give the government authority to quarantine astronauts in case they became contaminated with an alien virus during their moonwalk.

This regulation, best known as the Extra-Terrestrial Exposure Law was adopted by NASA in 1969. It stipulated that astronauts be kept in isolation for 21 days after their liftoff from the Moon in case there was a remote possibility that they were harboring "unknown lunar organisms that might endanger life on Earth." The rule was revoked in 1977 and formally repealed in 1991.

Women vote

Did you know that although American women were not universally granted the right to vote until 1920, state laws in New Jersey allowed them to vote as early as 1776 ? In 1790, when the New Jersey State Constitution was reformed, it formalized what the previous constitution had only implied: that propertied women could vote.

A few years later, a law expanded the previous election reforms and allowed women without "clear estate" to vote too. So, after the adoption of this 1797 law, the number of women voters at the polls significantly increased. New Jersey women enthusiastically exercised their rights until 1807, when the state finally restricted voting to white men.

Keep it classy

If you want to live in North California, you have to follow some rules of good taste. In 1998, the city of Wilson outlawed the keeping of upholstered furniture on front porches, on the basis that the practice was unsightly and tacky.

A year later, the town of Morganton followed suit, outlawing couches, recliners, and similar indoor furniture from verandas and yards. Mel Cohen, the city mayor at the time, said that outdoor furniture was drawing many complaints, so the city embarked on a quest to "beautify" the neighborhoods. Violators of the ordinance could be fined up to $300 for their offense.

Three-second hugging

Image: Mary Taylor

By the beginning of the 21st century, the rules of public displays of affection seemed to be changing and left previous generations in a state of confusion. In 2009, after noticing an increasing number of students embracing in the hallways, school officials in Hillsdale, New Jersey, implemented a "three-second hugging" rule. Apparently, adults were concerned that the constant displays of affection could disrupt the flow of hallway traffic.

Teenagers argued that the gesture was entirely unromantic and merely a way of saying "hello." However, schools preferred to go back to the old handshake in order to maintain an atmosphere of academic seriousness and to prevent any instances of unwanted physical contact.

Blue sundaes

Ever heard of "blue laws"? Blue laws are rules that once banned certain activities on Sundays, adopted originally for religious reasons. Blue laws often restricted business and recreational activities to encourage observance of the Christian day of worship.

For example, buying ice cream on Sundays was once illegal in Ohio because it was thought to be frivolous and luxurious. To circumvent this law, ice cream vendors began adding fruit toppings to disguise the frozen treat below and make it appear more "nutritious." This clever workaround ultimately led to the creation of the ice cream sundae.

Poking turkeys

Finding the perfect Thanksgiving turkey can be an artistry or a real challenge. How can you ensure that the well-rounded breast you pick up in the supermarket’s poultry section will turn into a delicious, juicy treat?

Everyone has their own strategy, but depending on which state you are in, your method might actually be illegal without you even knowing it. For example, did you know that in Los Angeles, California, it is prohibited to poke a turkey for sale in a meat market to check its tenderness? Don’t say we didn’t warn you!

Permanent marks

Carrying a marker in your pocket, purse, or backpack while walking the streets of California could land you in trouble. In the Golden State, it’s illegal to possess "broad-tipped indelible markers" —a.k.a. permanent markers—in a public space. Any person carrying a chisel, an awl, an aerosol paint container, or a harmless felt tip marker can be accused of committing vandalism.

The law is in place to curb graffiti and other forms of unauthorized street art. It is considered a misdemeanor and can be punished with up to 90 hours of community service, typically scheduled outside of school or work hours.

Go nuts!

Nuts can be a real problem for many people with food allergies. But even so, these laws prohibiting the consumption of nuts in public places may surprise you. For instance, in Boston, Massachusetts, it’s illegal to eat peanuts in church . Meanwhile, in Charleston, South Carolina, eating nuts on a public bus can result in a fine of up to $500 and as much as 60 days in jail.

If you thought it couldn't get any more specific than that, hold your horses! In Ridley Park, Pennsylvania, people are not allowed to eat peanuts while walking backward in front of the Barnstormers Theater during a performance. Probably the craziest law on this list, don’t you think?
