->''"Some have challenged my mathematics that Phil Reeves is 1000% local. I stand by my statement 10000% :-)"''
-->-- '''[[UsefulNotes/AustralianPolitics Kevin Rudd]]''', via Twitter

A person or object is described in some way that involves fractions. Oddly, those fractions don't add up to one. The most common form this description takes is "half [one thing], half [another thing], and half [something else]" or extended versions thereof -- hence the name -- but it can also involve more complicated addition problems. Another common variation is to have a character refer to splitting something "fifty-fifty," then realizing there are more people to split it among, and adjusting the proposed split to "fifty-fifty-fifty," etc. An occasional inversion is to say something is "half-something, half...just half-something" as an insult.

Sometimes this is used to suggest that the described thing is paradoxically larger (or smaller) than itself. It is almost always PlayedForLaughs, unless it's a really bad example of WritersCannotDoMath.

!!Examples:

[[AC:Film -- Live Action]]
* In ''Film/WillyWonkaAndTheChocolateFactory'', Willy says "Invention, my dear friends, is [[{{Technobabble}} 93% perspiration, 6% electricity, 4% evaporation]], and [[ArsonMurderAndJaywalking 2% butterscotch ripple]]." [[LampshadeHanging Mrs. Teevee points out that that adds up to 105%.]]
* ''Film/CaddyshackII'':
-->'''Jack Hartounian:''' My father was Armenian. My mother was half Jewish, half English, half Spanish.
-->'''Chandler Young:''' That's three halves.
-->'''Jack Hartounian:''' Oh, she was a big woman.
* In ''Film/TheProducers'', a lot of little old ladies are each sold a 50% or greater share of the profits of "SpringtimeForHitler" (which are expected to be negative).
-->'''Max''': Leo, how much percentage of a play can there be all together?\\
'''Leo''': Max, you can only sell one hundred percent of anything.\\
'''Max''': And how much of "Springtime for Hitler" have we sold?\\
'''Leo''': Twenty-five thousand percent.
* ''Film/MrsDoubtfire'' contains this variant:
-->"Is your sister English?"
-->"Half English, half American. Half-sister, really, so that makes her, what, about an eighth English? I don't know, I've never really done the math."
* In ''Film/AngerManagement'', Chuck claims to be "half Jewish, half Italian, half Mexican."

[[AC:{{Literature}}]]
* The Literature/{{Discworld}} novel ''Discworld/{{Eric}}'' has the Aztec-flavoured god Quezovercoatl, who is described as "half-man, half-chicken, half-jaguar, half-serpent, half-scorpion and half-mad", making "a wossname total of three homicidal maniacs".
* An epigram by Creator/AlexanderPushkin describes one of his contemporaries as a "half-milord, half-merchant, half-fool, half-ignoramus, half-scoundrel, but there's a hope he'll finally be full".
* In ''Literature/{{Animorphs}}'', Ax -- and by extension the Andalite race in general -- is once described as half blue deer, half centaur, and half scorpion. Then the narrator {{Lampshade}}s it by saying they realize that it's too many halves.
* From the KnownSpace book ''Destiny's Forge'':
-->'''[[ColonelBadass Tskombe]]''': Half a sense of adventure, half a sense of duty, half no better plan for my life.
-->'''[[LadyOfWar Cherenkova]]''': That's three halves.
-->'''Tskombe''': If I was smart enough to do math I wouldn't be in the infantry.
* When Creator/EricFlint expanded ''Literature/SixteenThirtyTwo'' from a one-off novel to a SharedUniverse, he set out to avert this trope, by laying down rules for what characters other writers could create. Otherwise,
--> ... In addition to the half who are rocket scientists and the other half who are SEALS, Eric has provided us a list of the following additional halves:
--> The half who are engineers, which are in turn divided into half electrical engineers, half locomotive engineers, half chemical engineers, half mechanical engineers, and too many thirds and quarters to count.
--> ...
--> There is, I believe — at last count — exactly one person in everybody's fantasy Grantville who is elderly and illiterate. Of course, he's also the son of Alvin York and shoots even better than his daddy. "[[http://1632.org/authors_manual/many_halves.html The Many Halves of Grantville]]"
* The mythological hero Gilgamesh was described as "two-thirds god, one-third man". Exactly how that worked out is one of the many pieces of ''TheEpicOfGilgamesh'' lost to history.

[[AC:LiveActionTV]]
* At the end of the ''Series/{{Seinfeld}}'' episode "The Sniffing Accountant", Jerry describes his shirt as "half silk, half cotton, half linen".
* One episode of ''Series/AllThat'' revealed that BritneySpears is "[[http://www.youtube.com/watch?v=SOXp35sDaTc half girl, half robot, half ravioli]]."
* From a Creator/DemetriMartin bit discussing his ideas for mythological creatures:
-->'''Demetri:''' A very beautiful mythical creature is called the Zebratard, and this animal is one-half pig, one-half eagle, one-half zebra, making it an improper fraction - so that's three halves of a creature, that's one-and-a-half mythical creatures - and it's surprisingly graceful, and very rare.
* In one episode of ''Series/{{Farscape}}'', Crichton (while posing as a bounty hunter) suggests splitting a bounty 70/30; the other bounty hunter demands it be split "70/''40!''" Crichton, who clearly knows he's dealing with an idiot, ups the bid to 80/40 to calm him down.
* ''Series/StargateSG1'', when the team needed to use the power source of a bomb in order to power up the gate and dial out, Vala estimated a 70% chance they'd dial out and a 50% chance the bomb would explode. When Mitchell pointed out that this totaled 120%, Vala states that there's a 20% overlap where both happen, subverting this trope.
-->'''Mitchell''': Jackson, you get all that?
-->'''Jackson''': Yep. 100% chance we should have brought someone who knows what they're doing!
* In ''Series/{{Andromeda}}'', when talking about a madman's diary:
-->'''Harper''': It's half mystical mumbo-jumbo, half putrid poetry, and half bad math.
-->'''Rommie''': That's three halves.
-->'''Harper''': Like I said, bad math.
* In earlier seasons of ''Series/MythBusters'', Adam ([[GoodWithNumbers who averts this trope]]) would often give percentage chances of what would happen during an experiment. One of the few times Jamie tried to do this, this trope resulted. (Yes, even [[MemeticBadass Jamie]] can make mistakes.)
-->'''[[TheNarrator Rob Lee]]:''' Uh, Jamie, that's 125%.\\
'''Jamie:''' ''[chuckling]'' So sue me!
* In the ''Series/TheFlash2014'' episode "Plastique", Barry Allen enjoys a 500 proof drink. That's 250 percent alcohol by volume.
* On ''Series/ThirtyRock'', Jack describes an incredibly fancy dessert as being "topped with 25-carat gold leaf." Note that ''24''-carat gold is pure, 100% gold.

[[AC:{{Music}}]]
* The Non-Prophets song "Xaul Zhan's Heart" has the line:
-->"Half shark-alligator, half man, half amazing."
* Music/FortMinor wishes to remind us that [[EarWorm they are]]
-->"10% luck, 20% skill, 15% concentrated power of will, 5% pleasure, 50% pain, and 100% reason to [[TitleDrop remember the name]]."
** Which DOES add up if you consider luck, skill, concentrated power of will, pleasure, and pain in that ratio to be a valid reason to remember their name. Sort of like saying that my breakfast this morning was 100% bacon and therefore 100% tasty.

[[AC:ProfessionalWrestling]]
* Wrestling/{{WWE}}: Wrestling/MontelVontaviousPorter: "I am half-man, half-amazing, half-tag-team-champion... I'm so great, I'm the only man on Earth with three halves!"

[[AC:Radio]]
* CarTalk: Frequently, Tom & Ray would give the answer to last week's Puzzler, then promise "We'll have a new Puzzler for you in the third half of the show."
* ''Series/DeadRingers'', when parodying ''Location, Location, Location'', has Kirstie Allsopp introduce herself as "half-woman, half-scarf" and then Phil Spencer introduce himself as "half-man"... ''(silence)''

[[AC:TabletopGames]]
* This can happen in ''TabletopGame/DungeonsAndDragons'' 3rd edition due to abuse of the various "half-x" templates.
** Some [[AllThereInTheManual supplementary materials]] try to Handwave this by say that species that can produce half-X templates [[ArtisticLicenseBiology have such strong genes]] that the template still applies even if the child is a quarter or eighth of that species, but that still doesn't account for the fact that certain half-x templates have full blooded counterparts as templates and that the baseline races that these templates can be applied to include various {{Heinz Hybrid}}s, some of which are stated to be distant descendents of said templates. This means that you could have a [[DepartmentofRedundancyDepartment Fiendish Half-Fiend]] Tiefling who was [[UpToEleven 153% Fiend and 97% Human.]]
* Played with in ''TabletopGame/{{Munchkin}}''. Despite being built from the ground up to parody various role playing game clichés (and the entire concept of role playing games in general), the "Half-Breed" card only lets you play two Race cards at once, as the name implies. To play three Race cards, you'll need a "1/3-Breed" card. (But then, the rules encourage cheating...)

[[AC:VideoGames]]
* In one of his many boasts in ''VideoGame/RatchetAndClankFutureACrackInTime'', [[MilesGloriosus Qwark]] explains to Ratchet that "being a hero is 45% strength, 60% bravery and 10% raw intelligence". Ratchet doesn't fail to lampshade that something doesn't add up.

[[AC:WebComics]]
* In [[http://darthsanddroids.net/episodes/0509.html this]] ''Webcomic/DarthsAndDroids'' strip, Jim improvisationally describes Wookiees as being "kind of half-ape, half-dog, half-yeti hybrids." Pete [[LampshadeHanging notes]] that this makes them one-and-a-half times as big as you'd expect.
* When Grace, Nanase and Ellen return from fighting Damian in ''Webcomic/ElGoonishShive'', Mr Verres's reaction is "half-overjoyed that nobody he cared about was seriously injured, half-enraged over their recklessness, half-exhausted after a long night, and half-relieved that the Damian threat was over".
* ''Webcomic/LeftoverSoup'''s Ellen has a propensity towards this, as demonstrated both by [[http://leftoversoup.com/archive.php?num=8 her D&D 3.5 character]] (see Tabletop Games, above) and [[http://leftoversoup.com/archive.php?num=57 her description of the Filthy Hippie]].
-->'''Jamie:''' Seriously, did a fraction kill your father or something?
* In ''Webcomic/ChainmailBikini'', Josh's character is half-human, half-ogre, and half-dark elf.
-->'''Chuck:''' [[SarcasmMode What, did you have three parents?]]\\
'''Josh:''' Yeah, that sounds good.\\
'''Chuck:''' But that's impossible!\\
'''Josh:''' I don't think so. [[ComicallyMissingThePoint Ogres and dark elves are okay with polygamy.]]\\
'''Chuck:''' [[http://shawntionary.com/chainmailbikini/?p=39 That's not what I'm talking about!]]
* Ranger from ''Webcomic/EightBitTheater'' has described himself as a half-elven half-human ranger who is a quarter Lefeinish and a quarter half-orc. This puts his total genealogical percentage anywhere [[HeinzHybrid from 112.5% to 125%]], depending on what the other half of the half-orc is.
-->'''[[KnowNothingKnowItAll Red Mage:]]''' According to my calculations, Ranger has seventeen grandfathers, [[InsaneTrollLogic two of whom haven't been born yet.]]

[[AC:WesternAnimation]]
* In the ''WesternAnimation/SouthPark'' episode "[=ManBearPig=]", Al Gore describes the eponymous monster as being "half man, half bear, half pig." When we actually see [=ManBearPig=] exactly as Gore imagines him in the Imaginationland episodes, it does in fact look part man, part bear, and part pig in some proportion. Other characters [[LampshadeHanging point out that this is too many halves]], and instead describe it as "half man and half bearpig", or some such version.
* The Charlie Dog character from ''WesternAnimation/LooneyTunes'' had jokes about this as one of his main schticks. He would claim to be 50% of about half a dozen different breeds.
-->'''Charlie:''' I'm 50% Pointer (There it is! There it is! There it is!), 50% Boxer, 50% Setter (''Irish'' Setter), 50% Watch Dog, 50% Spitz, 50% Doberman Pincher. But, mostly, I'm all Labrador Retriever! If you doubt my word, get me a Labrador and I'll retrieve it.
* Bender from ''WesternAnimation/{{Futurama}}'' has claimed at various points to be 30% iron, 40% zinc, 40% titanium, 40% lead, and 40% dolomite (that last one having at least some demonstrable truth to it because he survived swimming in molten lava). According to the professor he's mostly made up of a titanium-osmium alloy with a .3% nickel impurity.
* A ''WesternAnimation/HouseOfMouse'' short has the Big Bad Wolf telling his son that catching pigs is "fifty percent" whatever lesson he's trying to teach at the moment. Eventually, the son dryly informs him of just what all the "fifty percents" add to by that point.
* ''WesternAnimation/TheSimpsons'' episode "Homer at the Bat" had Burns attempting to improve the plant baseball team by hiring a hypnotist:
-->'''Hynpotist''': You are all very good players...\\
'''Team''': ''[entranced]'' We are all very good players...\\
'''Hypnotist''': You will beat Shelbyville...\\
'''Team''': ''[entranced]'' We will beat Shelbyville...\\
'''Hypnotist''': You will give one hundred and ten percent...\\
'''Team''': ''[entranced]'' That's impossible. No one can give more than one hundred percent. By definition that is the most anyone can give...
* In the ''{{WesternAnimation/Arthur}}'' episode "Tales from the Crib", when the mischievous Tibble twins invent a monster to frighten DW from moving out of her crib.
-->'''Tibbles''': ''Aracnar, Lord of the Spider People.'' He's half-man, half-spider, and he eats children. He can't get his tentacles through the bars of the crib, but kids in beds are ''easy'' picking! He climbs up the side, and crawls under the sheet!
-->'''DW''': Wait a second! If he's half-man, half-spider, why does he have tentacles?
-->'''Tibbles''': ...uh, he's half-octopus too! And half TyrannosaurusRex!
* A ''WesternAnimation/LooneyTunes'' short with Daffy Duck hosting a show exploring the "Mysterious Phenomena of the unexplained" has Daffy explain that the {{Chupacabra}} is "Half Alien, Half Vampire, Half Dinosaur"
* ''WesternAnimnation/KimPossible'' uses a variation on the "110%" version when Bonnie declares her intention of wresting the cheer squad captaincy away from Kim:
-->'''Bonnie:''' Which is... nice, but you gotta ask yourself, did you give the squad 110% today?\\
'''Kim:''' ''(annoyed)'' 120%, Bonnie.\\
'''Bonnie:''' I happen to think the squad deserves a captain who gives... like, 130!
* On ''WesternAnimnation/TotalDrama,'' [[TroubledButCute Duncan]] claims to have fought a mutant that was "half-lion, half-bear and half-poison."
* Cracked describes [[WesternAnimation/MyLittlePony Tirek]] as [[http://www.cracked.com/article_17129_7-badass-cartoon-villains-who-lost-to-retarded-heroes_p2.html "a gigantic half-goat/half-horse/half-man and 150 percent motherfucking hellspawn"]]. Yeah, seems they ''really'' like him.
* [[HalfHumanHybrid Irwin]] from ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'' is described as half-human, half-[[OurVampiresAreDifferent vampire]], and half-{{mummy}} in the "Underfist" special. Truth be told, he's quarter-human, quarter-vampire, and half-mummy, but that doesn't really affect [[spoiler: his supernatural vampire-mummy powers]] anyway.

[[AC:Other]]
* One standard email forward of student errors contains:
-->Handel was half German, half Italian and half English. He was very large.
* The "[[http://en.wikipedia.org/wiki/Ninety-ninety_rule ninety-ninety rule]]" of computer programming, which is due to Tom Cargill of Bell Labs:
-->"The first 90 percent of the code accounts for the first 90 percent of the development time. The remaining 10 percent of the code accounts for [[ScheduleSlip the other 90 percent of the development time]]."
* This quote from [[{{Baseball}} Yogi Berra]]:
-->Baseball is ninety percent mental. The other half is physical.
* MiltonJones has a variation on this trope: he makes a joke about his granddad, and then about his other granddad, and then about his ''other'' granddad, continuing through about eight different granddads. He then later [[CallBack calls back]] to this by complaining about family reunions. "Too many granddads."
** The granddad jokes usually end with "My grand''mother''... was confused."
* A non-comedic example; an old post on ''Website/FundiesSayTheDarndestThings'' had a poster who claimed UsefulNotes/BarackObama was 50% white, 44% Muslim, and 12% black.
* This is always the case for betting odds, as it allows the bookies to make money.
** To see why this is so imagine a person who bets once on every possibility available. They have effectively bet on an event with actual probability 1, but since more likely events pay out less and the bookies odds add to more than 1, the person loses money to the bookie whichever result happens.
* Fermions such as quarks and leptons have the bizarre property of [[LogicBomb having a different orientation after a rotation of 360°]]. They require a full 720° to remain unchanged.
