One Mario Limit / Real Life

Politics and Military

• An infamous person whose both first and last name are forever associated with is none other than Adolf Hitler, with the Hitler Ate Sugar effect being at play:
  • "Hitler" is a rare variation of the German surname "Hiedler". It wasn't common to begin with and in the aftermath of World War II, most bearers legally changed it.
  • "Adolf" (and variants Adolph and Adolphe)^note The Spanish and Italian variant "Adolfo" is exempt from this however. became an Embarrassing First Name for the creator of Adidas, Adolf Dassler, who exclusively went by "Adi". Harpo Marx's real name was "Adolph Marx" but he went by "Ahdie" and later changed it to "Arthur".
• The Presidents of the United States have quite a few examples among them:
  • The last names "Lincoln", "Kennedy" and "Nixon" are strongly associated with the American presidents bearing them. Then there's "Roosevelt" which is even more the case as it's borne by two presidents, Theodore and Franklin.
  • When hearing the first name "Woodrow", most will think of Woodrow Wilson who kickstarted the popularity of the name and also ended it due to being viewed with more contempt in hinsidght.
  • The arabic name "Barack" is associated solely with president Barack Obama, and so is his last name for that matter.
  • "Donald" was for a long time synonymous with a cartoon duck, but is now strongly associated with president Donald Trump. It helps that it was already considered an Outdated Name with very few relevant bearers, most going by "Don" or "Donny" anyways. The surname "Trump" is a greater example; exclusively associated with Donald and his family.
• Russia also has a few examples among its leaders and political figures:
  • Grigori Rasputin whose last name is monopolized in the literal sense has it has nearly no other bearers outside of his family.
  • Joseph Stalin is an odd and infamous example as "Stalin" isn't an actual Russian surname, but one he came up with, allegedly from Russian "сталь" (stal) meaning "steel" with the "-in" being a standard suffix for Russian last names. Still, the name does exist as an uncommon French form of the German surame "Staehlin".
  • Vladimir Putin and his family have the monopoly on their surname. Notably, the 1984 novel The Hunt for Red October features a character named Ivan Putin years before the rise in fame and infamy of President Putin, this isn't something that can be done nowadays.
  • Before Putin, there were Mikhail Gorbachev and Boris Yeltsin who monopolized their surnames.
• "Churchill", despite being not that rare as a British surname, is solely associated with Prime Minister Winston Churchill. The name "Winston", while not having as strong an association, has still gained the reputation of being fit for a Quintessential British Gentleman thanks to Churchill.
• There will only be one Napoléon. Well, technically, there was his nephew Napoleon III who was president of France and later became Emperor himself, for a longer time in fact, but pretty much stuck in the shadow of his uncle, whose historical impact is so big it would be hard to overshadow him.
• A few manufactuers of firearms now have their surnames becoming synonymous with the guns they made:
  • "Kalashnikov" is the last name of Mikhail Kalashnikov and now tied to his invention, the AK-47 riffle and its improved models.
  • The already uncommon surname "Glock" (German for "Bell") comes from Gaston Glock, creator of the homonymous pistol.
  • In the United States, there's "Remington", Colt" and "Browning".
• All The Rulers of North Korea have the names that synonymously associate with them. This fact even enforces by North Korean government to ban birth registrations using the same names with the leaders, and require existing bearers of these names to change to a different one. This association even extends to South Korea too, enough to make LOONA's Kim Jung-eun goes by stage name Kim Lip.

Writers

• William Shakespeare is nearly always referred to by his last name alone due to how unusual and tied to him it is. Note that many characters created by Shakespeare are also example of this trope.
• "Astolphe", the French form of German "Astolf" is a name that has only one notable bearer so far, French writer Astolphe de Custine. One can suspects that it sounding to close to the aforementioned "Adolph" may be to blame for the lack of resurgence of the name. The Spanish and Italian variant of the name "Astolfo" is also monopilized by a (fictional) Frenchman thanks to the Fate Series.
• "Rudyard" is the forename of Rudyard Kipling and pretty much no one else.

Musicians

• All Elvises are direct shout outs to The King. The ones who are not are forced to use their full names.
  • Elvis Costello named himself in reference to Presley. And he sometimes released music under the pseudonym "The Imposters". His last name competes only with Lou.
  • Merengue singer Elvis Crespo (of "Suavemente" fame) was named after THE Elvis.
  • Folk singer Elvis Perkins was named after The Elvis by his father, actor Anthony Perkins.
  • A Swedish series of children's books by Maria Gripe features a young protagonist named Elvis by his Presley-loving mother. (Swedish children are NEVER named Elvis unless it's a tribute to The King.^note Though there is a Norse name Alvíss, it is unrelated etymologically.) After The King dies, his mom starts calling him Edwin or Edmund.
• Don't expect to be hearing of any pop singers named Britney in the future. Britney Spears owns the name. The name "Britney" in general is this, as it's even a redirect to her page on Wikipedia ("Brittany" and "Brittney" haven't been hit as hard, but they're not immune).
• The name of multiple African origins "Kanye" is monopolized by rapper Kanye West, whom according to, his name fittingly means "the only one".
• Shakira isn't a particularly common Hispanic name, but it's not rare either. That being said, pretty much everyone bearing the name has had to deal with the inevitable "Hips Don't Lie" jokes.
• When Madonna Ciccone's given name is that uncommon and that strongly associated with one person, many people assume "Madonna" must be a stage name. Her name is only rivaled by the Virgin Mary.
• Elton seems safely secure nowadays.^note except for german-speaking countries, where Stefan Raab turned his voiceover guy Elton into a celebrity of his own.
• "Ozzy" is an alternate spelling of the real name "Ozzie" but is used mainly as the nickname of John Osbourne, with or without his last name alongside it.
• Out of "respect" for the Queen of Soul, Aretha is fully off-limits.
• Adele isn't that rare of a name, but now it is mostly associated with the British singer, especially after her international breakthrough in 2011. She's the reason that Adele Sandé goes by her middle name Emeli. In fact, her article on That Other Wiki is at simply "Adele."
• Deliberately invoked by Tay Zonday. He said in an interview he picked the name because it was the first one he came up with that didn't show any other significant personages in a web search.
• The Beatles: There are many people named John, Paul, and George, but there is only one Ringo. At least, outside of Japan; it was a nickname based on the rings he wore, but it also happens to be the Japanese word for "apple" (a coincidence which Japanese commercials have parodied).
• Korean Pop Music
  • There is only one Boa.
  • The K-pop companies can't have any idol with the name "Jungkook" anymore, unless you expect him to forever be associated with BTS. While most of the other BTS members use stage names^note  save for Jimin, whose unisex name is used by several other idols (albeit mostly female), fans refer to RM (Kim Nam-joon) and V (Kim Tae-hyung) by their real names regularly enough for "Namjoon" and "Taehyung" (at least the specific spelling in the latter's case) to be off limits as well. Same goes for "Yoongi" (Suga), "Seokjin" (Jin), and "Hoseok" (j-hope) to lesser extents.
  • Although Hyuna (pronounce hyun-ah) is a real and common Korean name, in K-pop industry, the name is unsurprisingly associated with Hyun A.
  • "Jisoo" is a common unisex name in Korea, but everywhere else it refers almost exclusively to the BLACKPINK member. She’s not the only idol who goes by that name, but the others are far more obscure in the West. This is likely why the ITZY member uses the stage name "Lia" instead. On the flip side, though common Western names, "Jennie" and "Lisa" are unlikely to be used by any other K-pop idol without being associated with the Blackpink members.
  • TWICE being one of the most popular girl groups internationally, combined with none of the members using English names professionally, means that at least some members (particularly Nayeon, Jeongyeon, and Tzuyu) have had their names associated almost exclusively with them outside of Korea.^note Japanese members Mina, Sana, and especially Momo are the major exceptions despite the latter two not sharing their names with other K-pop idols. Chaeyoung is the biggest exception in the K-pop community, where Jihyo has a Two-Mario Limit with actress Song Ji-hyo. Tzuyu has pretty much monopolized the Wade-Giles Romanization of the Chinese name Ziyu.
• If your name is "Alanis", chances are you're gonna be the butt of many jokes relating to that Canadian woman who doesn't know what irony is.
• Jimmy is a common name but Jimi is only associated with Jimi Hendrix.
• Many classical composers have last names that are associated solely with them, including Mozart, Beethoven, Schubert, Chopin, Liszt, Tchaikovsky, and Shostakovich.
• The name "Reba" is solely associated with Reba McEntire, to the point that she's listed as just "Reba" on the singles charts and on all of her albums since 1987's Reba.
• "Way" as a surname is associated primarily with My Chemical Romance frontman Gerard Way and his brother, bassist Mikey Way. One does not need to read My Immortal to guess that the "Way" in Ebony Dark'ness Dementia Raven Way is a Shout-Out to the brothers.

Actors

• Tom Hanks had a speech regarding actors who can be identified by a single part of their name, Denzel Washington standing out as in his case, it's his first name.
  Brando; Clift; Poitier; McQueen; Hoffman; Pacino; De Niro. Now the cliche "the list goes on-and-on" does not apply here–because it doesn't. The list is finite, the club is exclusive. A single name can define an artist who is a peer and equal with all of the greatest legends of our craft. If Washington doesn't ring loud enough, then let the first name carry all the weight. And that name is Denzel.
• It's hard to think of a "Keanu" other than Mr. Reeves.
• "Dwayne" is limited to Dwayne "The Rock" Johnson in term of popular knowledge. It's alternate spelling "Duane" is immune to this.
• "Schwarzenegger" is a rare German last name that will never live down its association with actor and politician Arnold Schwarzenegger. Even his first name to an extent is a victim of this, having spawned its own trope The Ahnold.
• "Toby" is a very common name, but when spelled "Tobey", then it means you're talking about Tobey Maguire.

Scientists

• "Einstein" is solely associated with Albert Einstein. In popular culture, this name is synonymous with "clever" just like "Sherlock" is synonymous with "insightful".
• Nikola Tesla has made the Slavic surname "Tesla" not only synonymous wiht himself but with sciencitfic achievements ahead of their times as a whole. The name "Nikola" (a variant of "Nicholas") is also very tied to him.
• Several medical and neuro-developmental disorders are named after the discoverers of these conditions. Asperger and Tourette are possibly the most notable offenders.

Sport and Professional Wrestling

• When you mention the name "Kobe", you almost always get former basketball star Kobe Bryant instead of the Japanese city, the meat, or League of Legends caster Sam "Kobe" Hartman-Kenzler.
• Similarly, "Ichiro" nowadays has pretty much been taken over by former baseball star Ichiro Suzuki, whether you're in Japan or North America. His page on the Japanese Wikipedia is at "イチロー" (romanized as "Ichirō") instead of his actual Japanese name of "鈴木 一朗" ("Suzuki Ichirō").
• Stephen Curry is pretty much the only man who can use the nickname "Steph", as it's otherwise exclusively reserved as a shorthand for the female name Stephanie. Even the pronunciation of his name ("Steffen" instead of "Steven") qualifies.
• Usain is mostly associated with Usain Bolt, the Jamaican Olympic sprinter.
• Outside of India, Jinder Mahal has OML'd the name "Jinder".
• The surname "Hogan" is primarily associated with Hulk Hogan, despite it not being his real name and Colonel Robert Hogan predating him by decades.
• The name "Shaquille" will forever be associated with famous basketball player Shaquille O'Neal.

Businesspeople

• Disney is the name of the world-wide known biggest entertainment media company and nothing else. It is actually named after its founder Walt Disney but no writers would name their fictional character "Disney" by fear of copyrights among other reasons.
• The uncommon name "Elon" is associated only with billionaire and founder of Space "X", Elon Musk.
• Creator of Facebook, Mark Zuckerberg is more often simply called "Zuckerberg" or even "Zuck" whenever he's being referred to. On a similar note, he enforced an ownership of his name on his own social media, meaning people also named Mark Zuckerberg cannot use their name on their Facebook profile and must at the very least, add a middle initial.

Geography

• Although "America" is actually a personal name (such as America Ferrera), most people, especially outside anglophone and hispanophone countries, almost only associate this name with the continent, or more particularly the United States.
• "Albert" is a widely common name, but its feminine form "Alberta" is definitely belong with a certain Canadian Province.
