California’s state animal is extinct

Image: Levi Meir Clancy

The California grizzly bear adorns the state flag, but you won’t find one in the wild anymore. Once abundant throughout the region, this was a subspecies of Grizzly also known as "California golden bear."

By the 1920s, this majestic animal had disappeared from the wild, but it has remained a powerful symbol of the state, featured on the flag since the Bear Flag Republic’s short-lived attempt to break from Mexico in 1846.

The American flag was (probably) designed by a teenager

Image: Sharefaith

In 1958, around the time Alaska and Hawaii were being added to the Union, an Ohio high schooler named Robert Heft stitched a 50-star flag for a class project . His teacher gave it a B–, scoffing that the brand-new design "lacked imagination."

However, not long after, Heft’s design was selected from thousands of submissions sent to President Eisenhower to determine the official flag. That teacher later changed the grade to an A.

Texas’s state dish may have been invented by prisoners

Chili con carne is the Lone Star State’s official dish. While its exact origins are uncertain, some say that Texan prisoners in the 1800s were the minds who concocted the dish. According to this version, the stew—made with beans, thin strips of beef, and chili peppers—was the local equivalent of bread and water: a kind of Texan gruel .

Alabama's state nut was once a life-saver

Image: Antoni Shkraba

Pecans aren’t just Alabama’s official nut—they’re also symbols of resilience from the Depression era. When cotton crops failed in the 1930s, families turned to harvesting pecans to survive. The nuts became a form of currency , traded for goods, and even used to make mortgage payments. Today, Alabama produces over 30 million pounds annually.

The Star-Spangled Banner was once a drinking song

You may know that America’s anthem has a boozy British past. The melody originated as "To Anacreon in Heaven," a raucous 18th-century tavern tune sung by a London gentlemen’s club. A relative of Francis Scott Key noticed that his poem fit perfectly with the melody—and thus, the anthem as we know it was born.

The Great Seal almost had a turkey

Image: Roman Manshin

Can you imagine if the Great Seal of the United States featured not a mighty eagle, but a turkey? It was none other than Benjamin Franklin who proposed the turkey as America’s symbol, calling it " a bird of courage ."

Instead, he dismissed the bald eagle as "a lazy scavenger." Congress ultimately overruled him, but Franklin did have a point: turkeys are known to be fiercely protective.

The flag’s colors weren’t meant to mean anything—at first

Image: Jon Tyson

Red, white, and blue may seem deeply symbolic today, but in 1775, the Continental Navy chose them simply to match the British flag’s palette. A rebellious decision, if you think about it. The "valor, purity, justice" meanings were tacked on later by poets and politicians.

Is South Carolina’s flag really what it seems?

Image: Jaden Dessureault

South Carolina’s flag features a blue background with a palmetto tree and what appears to be a crescent moon. But there are stories that sustain that the silver symbol isn’t a moon at all —it’s a gorget, the curved neck armor worn by 18th-century soldiers. Historians have searched for records to back this theory, but no nods to gorgets have officially been found.

Colorado’s flag was once a confusing disaster

Image: Olga Kovalski

When Colorado unveiled its bold "C" design in 1911, it forgot one crucial detail: specifying which shade of blue to use for the background. For 26 chaotic years, flags fluttered in everything from pale sky blue to deep navy—until officials finally standardized the hue in 1937.

One of Illinois’ state symbols was chosen by… kids

Image: Peter Schad

Illinois’ state snack was chosen by the most powerful lobbyists of all: children. When a group of fourth graders learned their state produced a large portion of America’s popcorn , they launched a 2003 campaign so persuasive that lawmakers had no choice but to make it official.

If you were an active and public Twitter user between the years 2006 and 2017, guess what? Your words are preserved in the Library of Congress .

The platform’s first twelve years are contained in a digital collection meant as a historical record of a new communications channel. From 2018 onwards, the Library started acquiring only "particularly interesting" tweets.

Oddly specific movies, like "Shrek" or "Wall-E"

The Library preserves film culture through the National Film Registry and other collections.

Recent registry additions have included animated hits such as Shrek , while the Library’s preservation programs and official announcements explain why even mainstream animated features matter as cultural artifacts worth saving. The Registry also contains enduring classics such as Grease , Citizen Kane , and The Wizard of Oz .

Specific songs, like "Livin’ La Vida Loca"

Music enters the Library’s life via the National Recording Registry and the Music Division. Ricky Martin’s "Livin’ La Vida Loca" is one of the recordings the Library has recognized for cultural impact; these entries help posterity understand what particular songs meant to listeners at the time.

Other anthems are also preserved in the collection, like Aretha Franklin’s " Respect " and Journey’s " Don’t Stop Believin. "

A moldy wedding cake

Image: gryzoon

A sliver of wedding cake from P.T. Barnum’s era spectacles survives in the Library of Congress’s Manuscript Division as a historical oddity. Donated in the 1950s, it now sits darkened with age and mold.

The cake came from the wedding of Charles Stratton, who was 25 years old and just 35 inches tall at the time. Stratton performed in Barnum’s shows under the name General Tom Thumb, delighting audiences with his song-and-dance routine.

Yes, that is a real thing. The Geography and Map Division highlights a 1991 topographic map of the Grand Canyon molded in chocolate , made by the Chocolate Topographic Company.

What Lincoln was carrying when he died

The Library’s Treasures and related pages describe the modest, deeply human contents found on Abraham Lincoln after he was shot : a silk-lined wallet with newspaper clippings, a Confederate five-dollar bill kept as a curiosity, spectacles, a pocketknife, a handkerchief, and a watch fob, among other everyday items.

Why not? The Library’s Manuscript and Music Divisions preserve numerous strands of hair attributed to notable figures : from presidents such as Thomas Jefferson to composers like Ludwig van Beethoven, as well as other cultural icons including Walt Whitman, Clara Barton, and George Washington!

Thomas Jefferson’s vanilla ice cream recipe

Among Jefferson’s papers, which the Library and Monticello both reproduce and discuss, is his handwritten vanilla ice cream recipe : cream, egg yolks, sugar, and vanilla, frozen using ice and salt. A fundamental (and surprisingly delicious) document of history!

A precursor of the Monopoly Game (The Office Boy)

Monopoly’s genealogy includes several predecessors. Most famously, Elizabeth Magie’s 1904 The Landlord’s Game is the well-documented precursor.

Other commercial board games , such as Parker Brothers’ The Office Boy (an 1889 Horatio Alger–style career game), along with various moral and occupational boards, helped shape the emerging mass-market game industry that ultimately produced Monopoly .

ALF

Image: Erik Mclean

In case you didn’t know, this beloved TV character’s name is not short for "Alfred." It actually comes from the term " A lien L ife F orm," but don’t be alarmed: This alien is as friendly as they come. ALF is the quirky and lovable adopted family member of the Tanner family, who gained the heart of the American public in the 80s and 90s.

ALF’s story begins after this alien’s spaceship crash-landed in the garage of the Tanner’s, a typical suburban American family. Although his many antics often bring trouble for the entire family, ALF’s big heart quickly makes the Tanners fall in love with him, harboring and keeping him hidden from the U.S. government.

E.T.

Are we in the presence of the most famous film alien in history? While we might not be able to answer this question (the remaining entries on this list might very well be as beloved), E.T. is definitively a heavy contender for this highly-coveted title. It’s been over 40 years since this extraterrestrial’s only on-screen appearance, but he still remains as iconic as he ever was.

Steven Spielberg’s 1982 film tells the story of Elliot, a typical American boy who befriends a lovable alien stranded on Earth. Elliot, alongside his family and friends, helps E.T. go back home, leaving us with a few of the most memorable moments in cinematic history.

Mork

Not every alien on this list has to look weird: Leave it to the amazing Robin Williams to portray one of the most beloved TV aliens in history. "Mork and Mindy" shows the adventures of Mindy McConnell, an American teenager who befriends an alien simply known as "Mork from Ork."

Not many know that this now classic TV show was an offshoot of another beloved American show, "Happy Days." Williams's only appearance in a Happy Days episode impressed producers so much that they decided to give this TV legend his first chance.

Marvin the Martian

Marvin the Martian might be the first alien on this list to pose a threat to mankind, but don’t worry: His plans usually backfire in a spectacular fashion, usually thanks to a wisecracking rabbit or to a lisping duck with anger issues.

Originally voiced by the legendary Mel Blanc, perhaps what’s more memorable about Marvin is his unusual design: You wouldn’t expect a creature of outer space to sport a red unitard, green skirt, nor a fashionable broom on his helmet, right?

Chewbacca

Image: Kadyn Pierce

If you had to describe Chewbacca to someone who had never seen the film, the image they would form in their head wouldn’t necessarily describe Han Solo’s partner in crime, right? After all, they would probably think of Chewie as some sort of huge and extremely adorable teddy bear, unaware of the danger they would be in if they called this iconic Wookie cute.

However, as ferocious as Chewbacca was to any Storm Trooper that dared to step in his way, he was also an extremely loyal and loving comrade to any of his many rebel friends. Few movie sounds are as memorable as Chewie’s deafening roar.

Xenomorph

First things first: In case you didn’t know, the titular alien species in the " Alien " film series does have a name. Well, sort of. These jet-black monstrosities are actually known as the Xenomorph . However, should you ask an etymology aficionado about what this Ancient Greek word actually means, the answer would simply be "an alien or strange creature." So, in a way, these creatures can simply be called "Aliens.".

In any case, few extraterrestrials have instilled so much fear into the hearts of moviegoers: Their razor-sharp claws, amazing strength, and acidic blood definitively make them one of the most dangerous creatures in film history. In fact, only one fictional alien species has been able to stand their ground against the vicious Xenomorphs and, as luck would have it, they are the next entry on this list!

Predator

Way before the 2001 movie "Alien vs Predator" pitted these two science-fiction juggernauts against one another, the Predator had already established itself as the deadliest hunter in the galaxy. This alien race lives for one thing and one thing only: To prove their skills by tracking and hunting down the most dangerous and exquisite creatures.

The 1987 film "Predator" introduced the world to this cold-blooded hunter by placing him in a terrifying environment: The film follows Vietnam War veteran Major Dutch (played by Arnold Arnold Schwarzenegger) and his efforts to escape the Predator that’s hunting them in the deep jungle. However, the second Predator film saw an even more unnerving scenario: The Predator hunting down prey in the streets of Los Angeles.

Mr. Spock

Image: Wonderlane

Is Mr. Spock on this list? It seems only logical. In a list almost entirely comprised of extraordinary and bizarre creatures, it only took a set of pointy ears to turn actor Leonard Nimoy into one of the most instantly recognizable fictional aliens in history.

Mr. Spock has been a staple of the Star Trek universe since the very first episode of the original show aired in the 1960s. Spock quickly became a fan favorite: His highly logical brain, combat skills and passion for science made him extremely interesting to TV audiences. Not only that, Nimoy’s deep voice and magnetic personality added to the depth of this character.

Mars Attacks!

Image: Derpy CG

When audiences saw Tim Burton’s 1996 black comedy "Mars Attack!," they were quickly enthralled by the menacing yet funny-looking Martians attacking our country. However, few of them knew that these aliens were actually much older, dating back to a 1960s trading card game produced by Topps.

The lore established by the trading card series and the film is pretty much the same: One day, our planet finds itself invaded by a race of Martians hell-bent on taking over our planet. While the Earth is first unable to defend against their superior technology, our tenacity and grit allow us to battle these hideous space invaders.

Superman

We’ll end this article with the last son of Krypton. Sometimes we tend to forget that Superman , a superhero believed by many to be the ultimate American icon, arrived on our planet as a baby from outer space. After his home planet was doomed, Kal-El’s biological father sent him far away across the galaxy, with his small vessel crash-landing into a small farm in Smallville, Kansas.

Baby Kal-El was found by Jonathan and Martha Kent, two farmers who instantly adopted him as their own child. Now known as Clark, the boy that would eventually become the "Man of Steel" found his powers at an early age, and set out to defend our world from all sorts of dangers.
