10 fantastically elaborate hoaxes are the kind of mischievous deceptions that make history both amusing and baffling. A hoax is usually defined as a humorous deception, and while many scams are driven by money, pride, or revenge, these particular tricks were pulled purely for the sheer delight of the pranksters, often demanding weeks or even years of careful planning.
10 Fantastically Elaborate Hoaxes Overview
10 Martin Marty and Franz Bibfeldt
Franz Bibfeldt was, allegedly, a German theologian who supposedly authored a massive body of work on the concept of Year Zero—the fleeting moment between the BC calendar’s end and the AD calendar’s start. Supposedly, his 1927 PhD dissertation was cited in numerous academic journals, lending an air of legitimacy to his nonexistent scholarship.
That claim is odd, because Bibfeldt never actually penned a thesis.
In truth, Bibfeldt never existed at all. He originated as a footnote in a hurried college essay. A student named Robert Clausen, pressed for a deadline, invented the name Bibfeldt and quoted him, banking on the professor’s lack of fact‑checking. His roommate, Martin Marty, found the fabricated scholar amusing, and the duo began peppering citations with Bibfeldt’s name across essays, the university magazine, and even library loan requests. Their prank escalated to ordering “books” by Bibfeldt from the campus bookshop—each request returned as out of stock.
Since his debut, the fictional Bibfeldt has been embraced by theologians with a sense of humor worldwide, especially at the University of Chicago’s Divinity School, where Martin Marty taught for 35 years, turning the hoax into a beloved academic in‑joke.
9 The Dreadnought Hoax
Virginia Woolf isn’t typically associated with practical jokes, yet in 1910 she and several members of the Bloomsbury circle pulled off a brazen stunt. Dressed in exotic costumes and darkened their faces, they convinced the Royal Navy that they were an Abyssinian royal delegation, with Woolf’s brother playing the emperor.
The group attempted to sound authentic by learning a few Swahili phrases—unfortunately, Swahili isn’t spoken in Abyssinia (modern Ethiopia), making their linguistic preparation largely useless.
Nevertheless, points for effort.
The Navy’s welcome committee, apparently none the wiser, escorted the “royal” party aboard the famous battleship HMS Dreadnought, giving them a full VIP tour. The pranksters even managed to hide an obviously fake beard, which fell off shortly after they disembarked, further exposing the ruse.
When the story broke, the Royal Navy was mortified and threatened legal action, but ultimately let the matter fade quietly—perhaps the best outcome given the thin disguise and the fact that the memo announcing their visit misspelled “Abyssinia,” a glaring clue the pranksters ignored.
8 The Banana Skin Hoax
The 1960s, a decade of love, peace, and psychedelic experimentation, also birthed a wild rumor: bananas, when processed correctly, could produce a hallucinogenic effect comparable to LSD. The myth gained traction after Donovan’s hit “Mellow Yellow,” which he claimed referred to a “yellow vibrator” but which some listeners mistakenly linked to a supposedly electrified banana.
The rumor spread that the white underside of banana skins contained the same chemicals as LSD, and a 1967 issue of the counter‑culture paper Berkeley Barb even featured a “Recipe of the Week” detailing how to extract the alleged drug.
And, indeed, the story caught fire.
Scientifically, bananas do contain serotonin, a precursor to LSD, but in minuscule amounts insufficient to cause any psychoactive effect. Nonetheless, the hoax persisted, with publications such as The New York Times and The Wall Street Journal reporting the supposed properties as fact.
Within months, the tale appeared in the 1970 Anarchist Handbook, further cementing its place in the cultural imagination despite being thoroughly debunked.
Even today the myth resurfaces from time to time, though no one has profited beyond perhaps banana growers, who may enjoy the occasional surge of curiosity‑driven sales.
7 The Maggie Murphy Potato Hoax
Some hoaxes demand elaborate scheming; others are delightfully simple. Joseph B. Swan, a Colorado farmer with a penchant for mischief, opted for the latter, concocting a fake potato variety he christened “Maggie Murphy.”
With the backing of a local newspaper, Swan announced that he had harvested a staggering 26,000 pounds of potatoes from a single acre, thanks to his miraculous new strain.
That’s a lot of spuds.
He didn’t stop there—Swan claimed a single “giant” potato weighed a mind‑boggling 86 pounds. To prove it, he and a reporter staged a photograph of Swan hoisting the enormous tuber over his shoulder, a picture that spread nationwide like an early viral meme.
The image appeared in newspapers across the country, but skeptical experts soon exposed the fraud: the “potato” was actually a wooden replica, expertly carved to look massive.
Even after the truth emerged, enthusiastic growers continued to write, begging for seeds of the legendary Maggie Murphy. Eventually, Swan grew tired of the charade, claimed the prized potato had been stolen, and announced his retirement from the spud business.
6 The Erotic Novel Hoax
Literary purists have long debated what constitutes “good” literature, and one group of journalists decided to test the limits. In 1969, 24 Newsday writers, led by columnist Mike McGrady, banded together to write a deliberately terrible novel titled Naked Came the Stranger, stuffing it with gratuitous sex scenes, wooden characters, and absurd dialogue.
Their hypothesis: a reputable publisher would snap up any book that could sell, provided it contained enough steamy content. The novel was indeed accepted, and even reviewed by major outlets such as The New York Times, which failed to recognize the spoof.
Surprisingly, the book climbed the bestseller charts, proving the writers’ point about market appetite for lurid material.
When the hoax was finally revealed, sales surged even higher, as readers scrambled to own the infamous “trash” that had fooled the industry.
McGrady and his collaborators publicly disclosed the ruse on The David Frost show, after which the book lingered on The New York Times bestseller list for 13 weeks.
A film bearing the same title was later produced, capitalizing on the notoriety despite having no connection to the original manuscript.
The episode suggests that defining “literature” may be an impossible task, or perhaps that readers simply love a good, scandalous page‑turner.
Who can say for sure?
5 The Plainfield Teacher’s College Football Team
The year 1941 witnessed a peculiar episode in sports journalism when Morris Newburger, a New York city dweller with a fascination for college football scores, wondered whether the back‑page box scores were ever fabricated.
He hypothesized that a clever prankster could simply phone newspaper editors and invent a fictional college team—Plainfield Teachers College—along with a fabricated victory over Winona, 27‑3.
This curiosity sparked the idea: could a completely made‑up team actually appear in the press?
Newburger called every major New York newspaper—including The New York Times, the Herald Tribune, and the Daily News—relaying the invented result. That Sunday, the Herald Tribune printed the score on its back page, and eleven other New York papers followed suit.
Emboldened, Newburger didn’t stop there. The next week, he announced another win, this time contacting both New York and Philadelphia papers, expanding the fictional team’s reach to two states.
As public interest swelled, Newburger installed a dedicated phone line for the “team,” drafted press releases, and even created a mascot and school colors—mauve and purple, a choice that raised eyebrows.
He further embellished the myth by inventing a star player named Johnny Chung, a half‑Hawaiian, half‑Chinese athlete standing 6‑foot‑3 and weighing 212 pounds, complete with a halftime snack description.
To cement the ruse, the group fashioned a fight song, blatantly borrowing the melody from Cole Porter’s hit “You’re the Top.”
The pranksters hoped to keep Plainfield undefeated, and for a while they succeeded—until Time magazine caught wind of the deception and exposed the elaborate hoax.
In a final act of mischief, Newburger sent a press release announcing that “due to flunkings in the midterm examinations, Plainfield Teachers has been forced to call off its last two scheduled games.” No newspaper printed that final update.
Thus, the fictional football team vanished as quickly as it had appeared.
4 The Chess Playing Automaton
The Mechanical Turk, an 18th‑century contraption presented as a chess‑playing automaton, was billed as a marvel that could outwit the world’s strongest players—essentially a pre‑modern version of Deep Blue.
Invented by Hungarian nobleman Baron Wolfgang von Kempelen, the Turk debuted before Empress Maria Theresa of Austria in 1770 and toured Europe for nearly a century, delighting royalty and commoners alike.
Despite its grandiose claims, the Turk was a clever illusion. Inside its ornate cabinet lay a hidden compartment where a skilled human chess master could sit concealed, manipulating the arm that moved the pieces.
Victims, often unnerved by the machine’s eerie presence, frequently lost quickly—perhaps more due to psychological pressure than any genuine mechanical superiority.
In truth, the Turk’s secret was a masterful blend of engineering and theatrical deception: the interior was designed so observers believed they could see through it, while a concealed door, hidden behind flowing robes, allowed the hidden player to slip in and out unnoticed.
The cramped, uncomfortable space where the human operator hid added an extra layer of hardship to the ruse, making the performance as taxing for the concealed player as it was entertaining for the audience.
3 The Dictionary Hoax
Lexicographers are not typically seen as pranksters, yet Rupert Hughes, editor of the Music‑Lovers Encyclopedia, managed to slip a bizarre entry into his reference work that persisted for decades.
The final entry, listed as “ZZXJOANW,” claimed to be pronounced “Shaw” and defined as a Maori word meaning “drum” or “fife.”
That definition raised eyebrows.
The entry remained untouched for roughly 70 years, despite the fact that the Maori alphabet contains only 14 letters—none of which are Z or X—and that Maori words always end in a vowel, making the entry linguistically impossible.
Even more puzzling, Maori musical traditions historically eschew drums, favoring other instruments, casting further doubt on the entry’s authenticity.
Speculation abounds about Hughes’s motive; some suggest he was sending a secret message to a friend named Joan Shaw, embedding a personal note within a scholarly tome.
Regardless of intention, the entry stands as a testament to how a single fabricated word can linger unnoticed in an otherwise reputable reference work.
2 The Science Fair Hoax
Most school science fairs showcase predictable projects—baking‑soda volcanoes, invisible ink, or potato‑powered clocks—but in 1997 a student named Nathan Zohner decided to push the envelope.
His project, titled “Dihydrogen Monoxide: The Unrecognized Killer,” presented water as a dangerous chemical, highlighting its potential to cause excessive urination, bloating, sweating, and even death, as well as its role in acid rain and metal corrosion.
Zohner distributed the report to 50 classmates, who, alarmed by the alarming facts, voted to ban the substance—unwittingly calling for the prohibition of water itself.
The experiment revealed how easily people can be swayed by authoritative‑looking documents, even when the subject is something as ubiquitous as H₂O.
After the project concluded, Zohner revealed that his true aim was to ask “How Gullible Are We?”—a critique of critical thinking deficiencies in the evaluation of scientific claims.
His clever deception earned him first prize at the fair, cementing the hoax’s place in educational folklore.
1 Johann Beringer’s Lying Stones
Dr. Johann Berringer, dean of the Faculty of Medicine at the University of Würzburg in 1725, had a fascination with “lapides figurati”—naturally formed stones that resembled recognizable shapes.
Two mischievous colleagues decided to prank him by “discovering” over 2,000 fabricated stones within six months, each purportedly depicting insects, animals, astronomical symbols, and even a Hebrew inscription spelling “Jehovah.”
The joke took a darker turn when Berringer, convinced of the stones’ authenticity, compiled his findings into the 1726 volume Lithographiae Würzburgensis, asserting that the figures were so precisely matched to the stones that they must be divine workmanship.
Despite subtle hints—such as chisel‑like marks on the stones—Berringer dismissed them, claiming only God could have crafted such perfect engravings.
When the hoax finally came to light, Berringer sued his two collaborators, leading to a scandal that tarnished the reputations of all three men.
In the end, the episode stands as a cautionary tale about scholarly hubris and the perils of taking every oddity at face value.
