Only Sane Man/Live-Action TV

"Carly: How come I can hear me?"
 * Jerry Seinfeld once talked about how the character he played on Seinfeld is actually funnier than the others because he "brings the sanity back" by making everyone else look just as crazy as they should in real life in comparison to him, and therefore even funnier than they otherwise would. This is especially true whenever another character tries to get advice from/explain whatever's going on to Jerry, who usually not only sees through, but plays along, often quite indulgently, with the other characters' bizarre motivations and logic.
 * Also subverted, as while Jerry thinks he's the only sane man, but it's more in comparison to his friends as he is shown to have a lot of troubles too, the most apparent being his tendency to break up for petty reasons, being a Neat Freak and being a bit of an Adult Child.
 * Rory from Doctor Who could also be considered this. Given that both Amy and the Doctor have Cloudcuckoolander tendencies, Rory often has to act as the voice of reason.
 * And not just in the Cloudcuckoolander sense either. Amy and the Doctor both have a tendency to abandon good sense altogether when they become too emotionally involved in a situation. Rory is easily the most emotionally stable of the three of them, making him the Only Sane Man in that regard as well.
 * In an episode of The A-Team, Face confides to a client that he suspects Murdock is the only one of the Team who is actually in touch with reality, "...and the rest of us should just be sprinkled over ice cream."
 * The customer in Monty Python's Flying Circus "Dead Parrot" sketch is another classic.
 * Likewise the customer in the "Cheese Shop" sketch, who finally takes the only "reasonable" way out of the situation and shoots the shopkeeper.
 * However, since this is Python and both characters are played by John Cleese, their sanity is relative.
 * A Bit of Fry and Laurie also makes good use of the "sane customer, insane shopkeeper" concept.
 * iCarly: Freddie, complete with volunteering for a Liz Lemon Job (almost exactly Liz Lemon's actual job, for that matter.) Also Carly early on but they seemed to move away from this so she could do more physical humor.


 * A Saturday Night Live sketch cast Norm Macdonald as a character in a musical (a West Side Story Expy), who questioned why everyone was spontaneously breaking into choreographed song and dance.
 * The Saturday Night Live "Jeopardy" sketches LIVE by this trope.
 * In the second "Hip Hop Kids" sketch the kids are trapped in a cave and Andy Samburg's character tries in vain to convince the others that having dance contests against bears is a very bad idea!
 * Saturday Night Live pretty much lives off this trope. The vast majority of non-political SNL sketches are based on the concept of one or more sane characters interacting with one or more insane characters. The main variables are the ratio of sane characters to insane characters and the way in which the insane characters are insane. Often, crazy characters recur through a number of sketches while their sane foils are variable. For example, the "Two A-Holes" sketches follow this.
 * Blackadder
 * Edmund Blackadder. Surrounded as he is by idiotic and / or mad superiors and underlings. For all his faults, Edmund is usually the only sane person around at any given time period. Unfortunately for him, if there are any other sane people around, they're usually gunning directly for him.
 * He's also a lot more savvy than most people around him in a historical sense as well, being able to recognize where his contemporaries cannot that the application of leeches to various body parts isn't an effective medical treatment, and that World War I is one long, muddy, blood-soaked and pointless waste of time and lives. "Whatever it was, I'm sure it was better than my plan to get out of here by pretending to be mad. I mean, who would have noticed another madman round here?"

"Dr. Crusher: If there's nothing wrong with me, there must be something wrong with"
 * In the first series, it is Baldrick, of all people, who has this role. He's more well-known as the Bumbling Sidekick he becomes in later series.
 * Dick Loudon on Newhart, where he dealt with eccentric, over-the-top characatures of people on a near-constant basis. George Utley (Tom Poston) is the nice but dim-witted handyman who is not too good at his job, but still insists that he'll be inducted into the handyman's Hall of Fame. Stephanie Vanderkellen (Julia Duffy) is the spoiled maid who also is virtually incompetent, while TV producer boyfriend Michael Harris (Peter Scolari) is the epitome of alliteration and yuppiness. There was Larry (William Sanderson) and his mute brothers, Darryl and Darryl, backwoods outdoorsmen who owned the Minuteman Cafe; Larry introduces the group the same way every time they make an appearance: "Hi, I'm Larry; this is my brother Darryl, and this is my other brother Darryl," and makes wild claims that often turn out to be true. Dick somehow tries to keep his sanity but finally snaps at the end of the final episode, "The Last Newhart" ... only for "Dick" to be the starring character in Dr. Robert Hartley's nightmare.
 * And Hartley was one of these himself on The Bob Newhart Show; with reason, because he was a counselling psychologist and most of the other characters were his patients, and Bob did deal with several sane people.
 * Richard on Keeping Up Appearances.
 * Oliver Douglas on Green Acres is either the most sane person, or the least--he's the only one who tries to view things logically, as it becomes increasingly apparent that in Hooterville, logic no longer applies.
 * In an episode of Thirty Rock, Kenneth's page jacket is ruined by Jenna and the only way he can get a new one is by competing in a "page-off" against the head page Donny - a secret underground NBC trivia contest. Pete catches them doing it as none of the pages are upstairs working, and says "What, are you kidding me? This is a billion dollar company. Donny, give Kenneth a damn jacket!"
 * Dave Nelson in News Radio.
 * Only sometimes. Occasionally he's completely crazy, and Lisa is the Only Sane Woman.
 * Greg from Dharma and Greg.
 * Greg's father, Edward, also counts. Although it should be mentioned he has long since resigned himself to the insanity that surrounds him.
 * While not as overt as Greg, Dharma is sometimes the Only Sane One, when Greg's quirks (like his over-organizing) come up.
 * The Daily Show portrays the studio host, Jon Stewart, as the Only Sane Man, with all his reporters being weirdos and lunatics with various obsessions and derangements.
 * The Daily Show also significantly revolves around playing clips of journalists and politicians looking foolish, cultivating the impression that Stewart is the only sane man in the entire country.
 * Jon Stewart has explicitly described The Daily Show's purpose being to point out the absurdities of government and the world. Since they focus on the crazy stuff (like pirates in the Indian Ocean), it's entirely logical that he looks sane comparatively.
 * Sometimes, the roles are reversed. For example, a scene on the aforementioned Indian Ocean pirates has John Olivier trying to talk about it seriously, while Jon Stewart is making a bunch of pirate jokes and puns.
 * On The Muppet Show, Kermit The Frog qualifies as the Only Sane Amphibian, although he cheerfully admits at least once that he's only surrounded by crazies because he hired them.
 * Contrast Sam the Eagle, who merely thought of himself as this.
 * Fraggle Rock's Boober frequently plays the role of Only Sane Fraggle; though not as often as he believes he does. The Minstrels have Murray as their Only Sane... Something.
 * Jim and Ryan each take on this role from time to time in the American version of The Office, although they seldom speak up for fear of losing their jobs.
 * Similarly Tim in the UK The Office. Not surprisingly, the actor went on to play Arthur Dent.
 * And more recently John Watson to the higher-functioning sociopath Sherlock Holmes in the BBC's Sherlock. Martin Freeman's made a career of it.
 * In recent years, Ryan has completely lost his Only Sane Man status after his short-lived promotion went to his head. As of 2009, the sanest, most level-headed man in Dunder-Mifflin is probably Oscar and he is all too aware of that fact.
 * Well, Jim is still sane (except for that one episode where he was holding the Idiot Ball), and (except for family-related drama--of which there has been a fair amount lately) Pam is too. Toby is also sane (when we see him), and in "Mafia," Oscar dubbed the four of them (himself, Toby, Jim, and Pam) the "Coalition for Reason" in the office.
 * Bobby from Supernatural fits this trope from time to time but the most notable is Tall Tales: Sam and Dean are bickering like an old married couple and are annoying the hell out of each other so Bobby is the only one to see that the Trickster is pranking both of them.
 * In Young Dracula, Chloe would often be the only character to notice how bizarre the situation actually was.
 * The Twilight Zone TOS loved this one.
 * "And When the Sky Was Opened": "My friends are disappearing!" "What friends?"
 * "Judgment Night": "This ship is going to be torpedoed!"
 * "The Fever": "A slot machine is following me around!"
 * "Mirror Image": "My doppelganger is stalking me!"
 * "A World Of Difference": "I've become a character in a movie!"
 * "Back There": "I tell you, the President is going to be assassinated!"
 * "Shadow Play": "This world is just a nightmare I'm having!"
 * "Nothing In The Dark": "Death is stalking me and wants to take me!"
 * "Person or Persons Unknown": "I am a real person! I exist!"
 * "The Thirty-Fathom Grave": "My dead shipmates want me to join them!"
 * "The Parallel": "I am not the person you think I am!"
 * "Nightmare at 20,000 Feet": "There's a monster on the wing of this plane!"
 * "To Serve Man": "It's a cookbook!"
 * Kochanski in the final two seasons of Red Dwarf. Previously, Rimmer had fitted most of the criteria for being an Only Sane Man, except for actually being any more sane than the other characters. They ignored him when he pointed out how ludicrous things were because his own opinions were equally ludicrous in a different way.
 * Michael Bluth in Arrested Development believes he's this. He really, really isn't, but compared to the rest of his family he may as well be.
 * Arguably, the OSM is the narrator/documentary crew.
 * George Michael fits the role pretty well. Maeby would be if not for her compulsive lying.
 * Used very creatively to Lampshade a would-be case of The Other Darrin on Due South. After the actor who played Ray Vecchio left the show, the next episode features Benton Fraser completely dumbfounded at another guy that shows up claiming to be him, with everyone else at the station also insisting that this is Vecchio. Eventually it turns out Fraser was left out of the loop for a bit that the real Vecchio is undercover with the mob, and the new guy is an FBI agent who's impersonating him.
 * Corner Gas has Lacey, although the title passes to Brent or Karen occasionally.
 * The Big Bang Theory has two Sane people in Penny and Leonard. Penny is there primarily to point out how hopelessly obsessed the geeks are, while Leonard is the only geek that has any understanding of human interaction.
 * lets not forget that Leonard frequently acknowledges what he and his friends are doing is completely insane
 * Dr. Crusher in the Star Trek: The Next Generation episode "Remember Me", who is the only one to notice people disappearing.

"Jane: Oh, Steve! How much longer? Steve: About the usual amount. Jane: How much longer in minutes Steve?"
 * In the Deep Space Nine episode "The Search Part II",
 * In the Star Trek: Voyager episode "Bliss", Seven of Nine, the Doctor and Naomi Wildman are the only ones who notice the crew acting strangely when they find an opportunity to get home.
 * Specifically,  Unfortunately,
 * Susan on Coupling is a rare female example of this trope - the only sane voice among oft-ranting, chronically insecure Steve, beauty-obsessed age-fearing Sally, Cloudcuckoolander egomaniac Jane, brain-dead misogynist Patrick and, well... Jeff.
 * Steve often fills this role when he's hanging out with Jeff and Patrick. Sanity is relative . ..
 * Er, I'm pretty sure Steve is always the one that sees things for what they really are with his honest takes of the insanity he sees around him (like the pointlessness of cushions on a chair, or the riduculousness of taking a lock off a bathroom door) without the social delusions that Patrick and Jeff hold. That's where the root of Steve's rants come from. While Susan is always the one that's insecure about her place (insecure about Steve still comparing her to Jane, insecure about him cheating, to the point of high pitched breakdowns that never see things from the rational overview). If anyone is chronically insecure, it's her. Her rants come from her own subjective insecurities.
 * The point of the show is to contrast the two normal people (Steve and Susan) with the two incredibly insecure people (Jeff and Sally) and the two excessively confident people (Jane and Patrick). Steve and Susan's relationship isn't perfect and they themselves aren't perfect; they both have perfectly normal flaws and neither ignore them nor obsess about them (much).
 * Jane of all people fills the role in "Sex, Death and Nudity", calling out Steve on his attempt to shift the blame for his refusal to come to the funeral onto Susan (despite her not being in the conversation), correcting Patrick when he fails to get that the aunt she just introduced to him is not the same as the aunt whose funeral it is, making an effort to clear the air with Susan, and expressing frustration with Steve when he gets an erection as a result of her talking about lesbianism.

"Reid: What is this rabbit hole I've fallen down?"
 * Unfortunately, it all comes undone when she's the only one to succumb to the Giggle Loop.
 * Benjamin Denton on The League of Gentlemen is the only sane person in his plot thread on the show. Similarly, in every scene set in the Local Shop, whichever character Mark Gatiss is currently playing will be the only sane man. He will probably also be tortured to death.
 * Alex Reiger on Taxi.
 * On Kyle XY, Josh kept a detailed notebook on all the strange things that happen around Kyle, and concluded he was a space alien, which he constantly mentioned. Kyle (who was actually an escaped lab experiment) later had to admit that Josh was the person who came the closest to figuring it all out.
 * Michael in My Family. Technically an Only Sane Boy, at least in the earlier seasons.
 * His father Ben only thinks he is.
 * Power Rangers RPM has the villainess Tenaya 7, who once spent an entire episode asking the Big Bad if his evil plan had failed enough for her to go take a nap.
 * There's also Ziggy, who is so Genre Savvy that you're surprised he doesn't look directly at the camera and inform the audience that yes, these people he hangs out with are serious.
 * At one point, he actually does look directly at the camera and inform the audience that these people he hangs out with aren't Rangers, they just play them on TV; as a way to segue into a behind-the-scenes episode.
 * Father Ted is the only more-or-less normal (albeit not particularly nice) person on Craggy Island.
 * Let us not forget Deputy Sven Jones and (most of the time) Jim Dangle on Reno 911!. They are the only ones who aren't violent, racist idiots, or holier than thou religious zealots. Or conversely, no one but no one is sane on Reno 911!.
 * In Buffy this happens a few times, generally due to magic addling people's minds. One example is in season 5 where Glory is using magic to obscure the fact that she and Ben share the same body. Only Spike, who's not human, is immune to the magic, and tries to explain to the heroes what's going on: everyone else is unable to understand what he's saying, bizarrely misinterprets him or ignores or forgets immediately.
 * "So, do we think that Ben and Glory are connected?"
 * "Is everyone here very stoned?"
 * Andy Travis of WKRP in Cincinnati. Created as the show's protagonist -- that's him being referred to in the theme song -- but the writers soon realized he was too dull to drive many plots and made it into an ensemble series with Andy at the bemused centre of the crazy.
 * John Crichton of Farscape usually manages to keep his head while all those around him are losing theirs. Justified by the fact that he is the only human in the main cast and aliens are likely to react to situations much differently, as well as by the fact that most of the rest of the crew are rebellious escaped prisoners who the Peacekeepers locked up for the sake of maintaining strict order.
 * On the other hand, Crichton actually shows clear signs of mental instability as a result of his experiences over the show. He does manage to pull himself together and get things done, but his base level is pretty off what would be considered ordinary.
 * And if you've ever sat and thought about what his American pop culture references must sound like through the Translator Microbes, you have to come to the conclusion that he must seem very insane indeed.
 * This includes yelling in faux-Klingon at a new companion who is good at picking up languages.
 * In the circa 1980 Sci-Fi Blakes Seven the cowardly thief Vila (Restal) was the only crew member to habitually question "Why risk near certain death to make one point that the news will suppress when we could set up somewhere and let people come to us if they want to?" Early in their career, female characters sometimes expressed similar opinions but they soon became either unthinking fighters or equally unthinking back-up. A lowly Delta class in The Federation's strict regimen, Vila is the only man always known by first name like the women, though he claimed once that it cost him a lot of money to get Delta ID "Because I did not want to be a spaceship captain risking my neck for the Federation".
 * Saffy in Absolutely Fabulous.
 * Nora of Life with Derek.
 * In one episode of Big Time Rush, James has sprayed himself with lots of orange spray, which is shown to them as "Hollywood Fever". Kendall, Carlos and Logan try to fix the situation, but Carlos ends up joining the Jennifers, and Logan becomes addicted to playing with bongos. Kendall is the only kid at the Palm Woods who manages to not change by this effect.
 * FBI Special Agent George Huang, M.D., on Law & Order: Special Victims Unit always sees the big picture, and is often the only reasonable person. If the rest of the cast ever actually listened to him, instead of using him to wheedle confessions out of perps, most of their problems would be solved.
 * On Soap, Benson usually played this role within the Tate household. Mary and Jodie took turns with the Sanity Ball in the Campbell household.
 * Degrassi hands off the hat of sanity to at least one character... usually. While one character has a zany poorly designed scheme, another character will be there to say "You're kidding, right?" The most consistent with the sanity hat are Jimmy, Ellie, and Clare. Jimmy is sane to offset Spinner's Attention span. Ellie paired off against Ashley, Marco, or Craig to point out when they were doing something stupid. Clare's paired off with Alli, who is on a mission to become popular, Clare gets to tell Alli when her popularity plans are dumb. Now, earlier I said most capable. All three of these examples have had off days, just not as many as the rest of the cast.
 * Paige and Holly J have at times invoked this trope, suggesting they might be the only sane woman at the school. However they don't have the hat of sanity as often as the above.
 * Like much of the tropes on TNG this has roots in the previous incarnations of the show. Snake was the only sane man of the The Zits as was Heather for the twins, Voula for Stephanie and Lucy etc. etc.
 * As the World Turns has Dr. Reid Oliver to act as a perpetual lampshade.


 * The League splits this trait between two characters, Pete and Kevin, who are seen as significantly more normal and well adjusted than their friends, and as such they are best friends.
 * X on Halfway Across the Galaxy and Turn Left is a female example. Not only does she have to live with a gambling-addicted father, a scatterbrained mother, and a Cloudcuckoolander sister, she is also has to keep said family safe from the enemies it's made entirely on her own at around age 10 (a result of her literally alien culture). Also contains a subversion as her younger brother is a genius but otherwise perfectly ordinary for his age - yet X seems see him the same way the rest of her cuckoo family, mostly because his slight immaturity and genius causes her no end of problems.
 * Travis Cobb on Cougar Town. Compared to the antics of his parents and their friends, the Only Sane Man is the 19-year-old socially awkward college freshman; however, he does occasionally indulge in their antics.
 * On Shameless, teenage Fiona is, for all intents and purposes, the caretaker of the family, and spends almost all her time looking after her siblings and her alcoholic father.
 * Luke Danes from Gilmore Girls.
 * Kai from Lexx, who, despite being a more-than-2000-years old, former-slave-of-his-worst-enemy, single survivor of an entire destroyed civilization as well as being dead still is the most rational, honest and intelligent member of his crew by far. Of course, the competition aboard Lexx is not what you'd call fierce...
 * By the halfway point of My Name Is Earl Earl himself has become this. He even has a mini-Heroic BSOD when he realises he is now the one sane and competent guy in Camden. This really comes into force as a major plot point in the prison-arc where Earl is the only sane guy in the entire prison, including the governor.
 * In Community episode The Science of Illusion Jeff starts to mention that he and Abed are this before Abed cuts him off.
 * In Community episode Horror Fiction in Seven Spooky Steps, it's shown that Abed has the highest sanity rating.
 * Josh Nichols.
 * On Maid Marian and Her Merry Men, Marian is the only sane person amongst the heroes and the Sheriff is the only sane one amongst the villains. At times, it appears that this pair may be the only sane people in medieval Britain.
 * Kenan Rockmore from Kenan and Kel would qualify as he almost always shouts out "WHYYYYYY?!" whenever Kel does something wrong.
 * In Frasier, Frasier Crane thinks he's this trope — his psychiatric skills are always on overload, analyzing his acquaintances with a keen eye and all-too-aware that he's surrounded by his anxious, foppish brother, his happy-go-lucky slob of a father, his violent-tempered, sex-crazed best friend, and his Cloudcuckoolander of a housekeeper who doesn't understand Americans. What he doesn't realize is that when it comes to reacting to the problems and issues in their lives, they are all far, far more well-adjusted and sensible than he is.
 * Martin frequently receives this role in the plots. He's not faultless, but if Niles and Frasier are doing something stupid it's a pretty good bet that he'll step in with some advice that resolves things.
 * Ted from How I Met Your Mother is an unconventional case, as he's a bit ditzy and is often neurotic, impulsive, and irrational, but he constantly reverts to this trope whenever his friends start going off the deep end, is often told that he acts like the group's dad, and usually is the person everyone runs to when they've got a problem. One of his most impressive demonstrations of this is in "False Positive", when the other four all chuck their dreams and plans away and make selfish, shallow, cowardly decisions, prompting Ted to dish out a brutal tongue-lashing and literally forbids them from doing anything of the sort -- they're going to do exactly what he tells them to do instead, or else. They are all extremely thankful for it afterwards.
 * Jonathan Creek already gets a mention under this trope's close relative Only Sane Employee, but for most of the fourth season he ends up being the only person involved in the production of "Eyes and Ears" (think Crimewatch with the production values of a Fox News chat show) who seems to care or indeed even notice how tasteless, factually inaccurate and generally awful it is.
 * Mac, Jake and Lyndon from Green Wing are the only sane people in the entire hospital, both getting dragged into the others' insane antics. Mac doesn't seem to mind any of this as he likes to play around with everybody else, though Sue is his limit but that's due to her stalking problem. Lyndon, on the other hand, can't stand any of it and gets more and more frustrated as it goes along. Jake doesn't get too caught up in it.
 * On The Red Green Show, Harold often tries to be the Voice of Wisdom trying to get his uncle and compatriots to see the foolishness of this week's Big Plan. After all, Harold does actually have a high-school knowledge of physics and other sciences, and so can usually predict how things are about to wrong, badly!
 * Subverted on Leverage. Nate believes he's the only sane man on the team because he's the only one who's not a thief. It quickly becomes apparent that he's an unstable, self-absorbed, risk-taking alcoholic and the rest of them, despite their law-breaking, are much closer to normal, or at least functional.
 * Hikonin Sentai Akibaranger, being a parody of Super Sentai, stars a team of Otaku. Mitsuki Aoyagi/Akiba Blue serves as the Only Sane Woman, in other words, the least Otaku of the team (AND the Mission Control, Mitsuki's more or less a closet one), and usually spends her time being bewildered at the ridiculous concept of the show.
 * Friends is a rather unusual example of this trope. In the beginning, Monica was definitely this (she was a 3, to be exact). However, as her obsessive-compulsiveness gradually shot Up to Eleven and Chandler's quippiness/snarkiness decreased, he gradually became the Only Sane Man of the group. Albeit more of a 2 than a 3.
 * In Magnum PI Magnum is a PI, Rick is a bartender at a posh club of the sort people only get into in movies, and is on friendly terms with gangsters and has an intelligence pipeline into the local underworld; and Higgins is a Major-domo of a rich man's estate and an absurdly cultured all knowing insufferable genius who loves telling war-stories that are so varied they end up putting in several continents at once doing several missions at once. TC on the other hand, has a mundane and respectable business flying tourists in a helicoptor, and off work he does laudable but equally mundane work helping local youth groups.
 * Downplayed with Lurch from most versions of The Addams Family. Usually his reaction to his employers' eccentricities is to roll his eyes, shake his head, or both. However, many times, his actions show he is Not So Above It All.
