7 Reasons Why We Say "Never Trust A Man With Two First Names" (And The Notorious Figures Who Prove It)
The cynical, yet catchy, proverb "Never trust a man with two first names" is one of those timeless pieces of cultural folklore that persists in modern conversation. As of December 2025, the phrase continues to pop up in everything from sports commentary to online dating advice, proving its enduring, if irrational, grip on the collective psyche. But where did this highly specific piece of advice actually come from, and is there any real evidence—historical, psychological, or linguistic—to back up the notion that a name like 'Billy Bob' or 'John Paul' spells trouble?
This deep dive will explore the true origins of the 'never trust' rule, dissect the surprising psychology behind our aversion to double names, and, most compellingly, reveal the roster of notorious figures whose infamous actions cemented the saying in popular culture, creating a fascinating, dark link between nomenclature and notoriety.
The Roster of Infamy: Notorious Figures With Two First Names
The primary reason this phrase resonates so deeply is not a linguistic quirk but a chilling pattern found in the annals of American crime. When we look at some of the most infamous figures in modern history, a surprising number share the two-first-name structure. These men, often known by their full names in headlines and court documents, created an undeniable, albeit circumstantial, link between the name style and a capacity for depravity.
- Lee Harvey Oswald: The assassin of President John F. Kennedy. His full name, a classic example of two common first names, is instantly recognizable and permanently linked to one of the nation’s greatest tragedies.
- James Earl Ray: Convicted for the assassination of Martin Luther King Jr. Like Oswald, his full three-name moniker is synonymous with a pivotal moment of violence in the Civil Rights era.
- Mark David Chapman: The man who murdered John Lennon. His double first name is a stark identifier in the story of a senseless, high-profile crime.
- John Wayne Gacy: One of the most notorious serial killers in American history, known as the "Killer Clown." The combination of John and Wayne, both highly common first names, adds a bizarre, almost folksy contrast to his horrific crimes.
- John Dillinger: A notorious and vicious bank robber and gangster during the Depression era. His name dominated headlines, cementing his status as a famous—and dangerous—criminal.
This historical pattern, where the full, double-first-name structure is used to identify the perpetrator of a shocking, high-profile crime, is the true engine of the proverb. It’s not about the name itself, but the way those names were immortalized in infamy.
The True Origin and Cultural Longevity of the Proverb
Despite the historical examples, the phrase's actual popularization in the 20th century is often attributed to a much more lighthearted source: cult television.
The Mystery Science Theater 3000 Connection
The saying was notably popularized by comedian Joel Hodgson on the television show *Mystery Science Theater 3000* (MST3K). Hodgson used the phrase with a memorable twist, saying, "Never trust a man with two first names, especially if one of them's a woman's." This specific, humorous version was often directed at the film producer Sandy Frank, who was a frequent target of the show's jokes.
The MST3K reference cemented the phrase in the lexicon of a generation, turning an old, vague suspicion into a recognizable pop culture punchline. However, older references suggest the saying existed long before, often shared as a piece of folk wisdom—the kind of advice a grandfather might dispense.
The Linguistic and Psychological Angle
Beyond the criminals and the comedians, there is a subtle psychological reason why a double first name might trigger a moment of hesitation or distrust.
- The Familiarity Bias: Research in behavioral economics and psychology suggests that people generally find names that are familiar, easy-to-pronounce, and common to be more likable and trustworthy. A name that follows an unusual pattern—like two distinct first names—can feel slightly "off" or less common, leading to a small, subconscious feeling of unease or 'otherness.'
- The Serial Killer Trope: The association is reinforced by the media’s naming conventions. Serial killers and high-profile criminals (such as David Berkowitz or Ted Bundy, who primarily used two names) are frequently referred to by their full names in the press to emphasize their identity and distance them from "normal" society. This media trope inadvertently reinforces the pattern.
- The Need for Distinction: Historically, double first names developed for practical reasons: to create more unique names for an expanding population or, ironically, to protect a child by giving them multiple names. This need for distinction, however, can be misread as an attempt to be overly memorable or even shifty.
The Case Against the Proverb: Trustworthy Men With Double Names
To truly debunk the proverb—or at least treat it as the piece of folklore it is—one must look at the overwhelming evidence of successful, trustworthy, and beloved men who possess two first names. The list of positive entities is far longer than the list of notorious ones, proving that the saying is a fun joke, not a reliable rule.
Successful and Respected Figures
The world is full of highly respected public figures whose names are composed of two common first names. These examples demonstrate that character, not nomenclature, defines a man.
- Matt Damon: An Oscar-winning actor and filmmaker, known for his long, stable career and philanthropic work.
- Elton John: One of the most successful and enduring musical artists in history, known for his activism and humanitarian work.
- Hank Aaron: Baseball legend and Civil Rights icon, widely considered one of the greatest and most respected figures in sports history.
- Darren Criss: Emmy and Golden Globe-winning actor and singer.
- Adam Scott: Highly respected actor known for his comedic and dramatic roles.
- Jason Alexander: Famous actor, particularly known for his role on *Seinfeld*.
- Billy Bob Thornton: While an eccentric figure, he is an Oscar-winning screenwriter and celebrated actor.
Even in the business world, figures like Dave Thomas, the founder of Wendy's, whose last name is a common first name, stand as counter-examples to the notion of inherent untrustworthiness. The sheer volume of successful, high-integrity men with this name structure proves the proverb is, at best, a superstitious joke.
Conclusion: A Proverb to Be Enjoyed, Not Followed
The enduring appeal of "Never trust a man with two first names" lies in its ability to take a random observation and connect it to a dark historical pattern. The saying is a perfect example of confirmation bias: we remember the infamous figures like Lee Harvey Oswald and John Wayne Gacy because their crimes were so shocking, and we forget the thousands of trustworthy men like Matt Damon and Hank Aaron.
In the end, the phrase is a relic of pop culture, a witty "neverism" popularized by figures like Joel Hodgson. It serves as a fun conversation starter and a reminder of the strange ways that language, media, and history intersect to create folklore. The next time you meet a John Paul or a Billy Ray, remember the proverb, but trust your gut—not your grammar. The only thing a man with two first names is guilty of is having parents who liked two common names.
