'''Basic Trope''': The one character who perceives the world to be insane.
* '''Straight''': Brad Gunther's friends are an [[AttentionDeficitOohShiny ADHD-afflicted]] school girl, [[MadScientist a nerd dealing in haphazard experiments]], a [[DumbMuscle muscle-bound twit]], and [[AlphaBitch a loud, boisterous teenage beauty queen]]. All the while, he's the only one who seems to notice their antics are a little off-kilter.
* '''Exaggerated''': The school-girl is a FunnyForeigner extraterrestrial from the Andromeda Galaxy, the nerd's trying to summon demons, the twit races cars ''on foot'' on a daily basis, and the beauty queen SpeaksFluentAnimal. All the while, Brad's the only one who notices that they're off-kilter.
* '''Downplayed''':
** Brad is part of a duo, serving as the StraightMan to a [[StraightManAndWiseGuy Wise Guy]].
** Brad is a RidiculouslyAverageGuy in a group of {{Cloudcuckoolander}}s.
** Brad put in any other situation he'd be the weird guy, but with how the rest of the cast acts, he's the only sane man by default.
* '''Justified''':
** His friends are trying to put on TheMasquerade, and don't want him to blow it.
** They weren't ''always'' this nuts; they became close friends when they were more normal, and Brad refused to leave them just because they started acting a bit weird.
** Occasionally Brad finds his friends a little weird, but he's so [[HatesBeingAlone afraid of being alone]] that it doesn't really matter to him.
* '''Inverted''':
** Everyone but [[CaptainOblivious Brad]] notices how off-kilter his friends are.
** Alternatively: [[CloudCuckooLander Brad is the only insane man]].
* '''Subverted''':
** [[ThroughTheEyesOfMadness Brad's really insane]]...
** [[NotSoAboveItAll Brad caves in and joins the madness of his friends]].
* '''Double Subverted''': ...But he's on to something.
* '''Parodied''':
** Everyone but Brad has genuine psychiatric disorders; the schoolgirl has dissociative identity disorder, the nerd behaves like a shell-shocked Vietnam veteran (complete with references to being in 'nam, despite obviously being far too young for that), the musclebound twit speaks to the voices in his head, and the beauty queen is under the impression that the demons going around stabbing everyone "just need a hug". Brad only stays with them because he's in school to become a psychiatrist and thinks it's good practice.
** Alternatively, Brad acts as the Only Sane Man to his {{split personalit|y}}ies, Bob and Ted.
* '''Zig Zagged''': Brad is the OnlySaneMan when the team is fighting crime, keeping his cool while his buddies panic. However, Laura (being the [[TheSmurfettePrinciple Token Female]]) is the Only Sane Woman when MsFanservice walks past, sending all the guys, including Brad, into a frenzy. And when the group goes to see The Only Sane Men in concert, the baton is passed to Joe, as he's the only one in the gang who isn't hopelessly obsessed with the band.
* '''Averted''':
** Everyone is portrayed to be relatively normal. Or at least two people.
** Alternatively: Everyone is completely crazy.
* '''Enforced''':
** "We need some sane person in this show; otherwise, no normal person would relate."
** Alternatively: "We need to throw in a sane guy to highlight and to react to the insanity of the rest of the cast."
* '''Lampshaded''':
** "It's like I'm the only normal person around here!"
** "Please. If I wasn't around, who'd point out how dumb you were acting?"
* '''Invoked''': Brad tries to find some insane friends. So he can laugh at their wacky antics and make snarky remarks about them.
* '''Exploited''': Brad uses his insane friends to make himself look better by comparison.
* '''Defied''': Brad finally gives up, lets loose all of his inhibitions and becomes just as bizarre as everybody else.
* '''Discussed''': "Brad, why on earth do you hang out with those weirdos?"
* '''Conversed''': "Is it me or is Brad the only normal person there?"
* '''Deconstructed''':
** The antics of Brad's friends bring him to a breaking point, and thus [[SanitySlippage drive him to insanity]].
** Alternatively: Brad begins to believe that they're all retards and fuckheads, and [[ScrewThisImOuttaHere starts to wonder if he should change group]].
** Alternatively: Brad mostly has begun to isolate himself from the others because he can´t stand them anymore.
** Brad is actually an EvilOverlord, but literally no one else knows it.
** The attributes that let Brad perceive how insane the world around him is, are the same attributes that make him [[StrawNihilist a cruel and manipulative nihilist who will happily commit any atrocity upon the messed up reality he despises as absurd.]]
** Brad looks like the only morally decent person with a lick of sense. But he's not, he acts like he's the normal one. But he's really a ManipulativeBastard who only hangs out with them to exploit their unusual weaknesses for his own personal gain.
** Brad considers himself the OnlySaneMan because he makes no attempt to understand his friends, and rarely even interacts with them aside from insulting their hobbies and rolling his eyes at them sarcastically. They soon stop hanging out with him.
** Brad thinks he's the OnlySaneMan but he's actually a clouldcookolandender Tsundere with potential SplitPersonalityDisorder
* '''Reconstructed''':
** A new guy joins the gang and takes Brad's place as the OnlySaneMan.
** Alternatively, after some [[ContemplateOurNavels navel contemplation]] and {{wangst}}, Brad realizes just how [[ThePowerOfFriendship important]] his group is, [[LoonyFriendsImproveYourPersonality as strange as they are]].
** Brad's friends realize what they're getting themselves into and start to appreciate Brad more.
Back to OnlySaneMan, before the rest of these nutcases infect you.
