Cow Tools

""What is the meaning of Cow Tools? What is the meaning of life?""

- Newspaper reader, The Prehistory of the Far Side

In many exotic locations such as the Bazaar of the Bizarre, the Black Market, the Mad Scientist Laboratory, the Wizard's Cave, Darkest Africa or The Future, there will be a lot of odd bits of mysterious... stuff... lying about. What is it? What does it do? Why is it there?

Well, chances are it isn't anything. While some of it may be a genuine bit of Applied Phlebotinum put there as Foreshadowing, much of the time it's just Cow Tools: props or artwork that the designer of the scene threw in to add to the color or atmosphere of the place. This doesn't stop the fans for wildly speculating about them, though. Noodle Implements are similar in regards to a Noodle Incident.

Named for a notorious The Far Side cartoon of the same name, showing a set of primitive-looking but vaguely familiar tools which a bipedal cow is showing off. Gary Larson would later say that it was the strip he'd gotten the most inquiries about, as people tried in vain to figure out what the hell they were for, when in fact Larson hadn't meant them to be anything but strange. Larson later said that he regretted having made one of the tools look vaguely like a saw, thus implying the rest had real-world counterparts. He got the idea from the recent discovery that some animals could use tools, and then wondered what it would be like if cows had tools. He thinks his biggest mistake was thinking this was funny—which it was, but for different reasons than what he intended.

On the other hand, the fact that there is No Such Thing as Bad Publicity no doubt attracted more readers to the strip and boosted Larson's circulation. Go figure.

One thing about Cow Tools is that it can be useful for hiding a clever Chekhov's Gun among them. Everything else has no purpose in the story, except for that one thing...

Apothecary Alligator is a particular cow tool that appears in many works and has a specific significance (but no apparent purpose). Empty Room Psych is a video game version of this- the empty room or mysterious device doesn't actually do anything, it's just for flavor.

Anime and Manga

 * Nearly every bulkhead in any starship or other vehicle designed by Leiji Matsumoto will be covered in an insane array of electronic instruments, usually glowing, circular, and inset into said bulkhead. They're affectionately known as Matsumoto Gauges, rhyming with Matsumoto Leiji.

Comic Books

 * Jack Kirby covered everything in Cow Tools. He was incapable of drawing a simple box; every device had innumerable chrome tubes, knobs, discs, and zigzags to no apparent purpose. Guess he wanted his machines to complement the dots they generated.
 * Parodies like Twisted Toyfare Theater have a ball with this. "Help me lift this giant piece of Kirby-esque machinery!"
 * The Sandman. Lying between every Call Back and Call Forward in Dream's storage areas is two or more utterly useless, but fantastical looking thingiemajjigs.

Fan Works

 * Bag Enders episode "A Shortcut to Whitby" features the "long bent thing with sort of a knob on the end" (inspired by a similar item on an episode of The Goon Show). The Fellowship lose it before they find out what it does, and the people who find it by the side of the road don't know either.
 * In All's Fine that Ends Okay, Kiku is sent a mysterious object which does absolutely nothing After that arc is resolved, it doesn't really do anything else, and no one actually figures out what it is or how it works.

Film
"Crow T. Robot: Increase the Flash Gordon noise and put more science stuff around!"
 * There is a scene in Tim Burton's Sleepy Hollow where Ichabod is doing an autopsy; there is a tray full of strange, complex looking surgical tools next to him. What they're for and how they work is anybody's guess, but they do resemble some of the more esoteric medical devices from the era.
 * Tia Dalma's hut in Pirates of the Caribbean: Dead Man's Chest is stuffed full of voodoo-related Cow Tools. There's so many that the one Chekhov's Gun among them ( boots) is easily missed.
 * Also of note was.
 * Also a subversion in Pirates of the Caribbean: the scene where Norrington reveals Jack Sparrow to be a pirate, he goes through Jack's seemingly only earthly possessions, which include a pistol with only one shot, a compass that doesn't point north, and a relatively normal sword. It seems to be a rather pathetic assortment of Cow Tools, however, over the course of the series, all of them end up being used. Ironically, the only item that ostensibly seemed to be of any practical use, the sword, was the least relevant to the series overall. The pistol and the compass prove to be highly significant Chekhov's guns in the first movie, and the sequels, respectively.
 * Dr. Orin Scrivello's rather painful-looking dentist's tools in Little Shop of Horrors certainly qualify for this.
 * They made a reappearance in Tim Burton's Batman as the plastic surgeon's equipment, too. And were Lampshaded with his forlorn "You see what I have to work with..." That was an Actor Allusion, as Jack Nicholson appeared in the original Little Shop.
 * The painful-looking torture interrogation information retrieval implements in Brazil are surely related.
 * Tony Stark's machine shop in Iron Man exemplifies this trope. At some points it seems like there's more stuff in there than you could possibly logically need to build a super suit, regardless of how complex that might be. Things like a pillar drill are necessary for any well-funded chronic tinkerer.
 * Among the various tools and equipment is the prototype for Captain America's shield. Tony uses it to prop something else up.
 * Famously Lampshaded in The Adventures of Buckaroo Banzai Across the 8th Dimension, where the labs are full of Cow Tools. "What's that watermelon doing there?" [in a hydraulic press of some sort]. "I'll explain later."
 * Itself Lampshaded in an early BattleTech novel, with the setup being recreated by a clear Captain Ersatz of Dr. Banzai. (It's later revealed to be . This actually becomes useful during a raid on the institute when.
 * In-universe, it was an experiment by the Banzai Institute on how to treat food so as to be easily airdropped into famine-starved countries without damaging the food (by making it bounce or resist crushing; the experiment was abandoned when someone realized that any food that could survive an airdrop would be too tough to eat). Behind The Scenes, it was explicitly an attempt at Getting Crap Past the Radar on a production which had been besieged by meaningless Executive Meddling (including a screaming Flame War over whether Buckaroo would be allowed to wear red-framed glasses onscreen). The director and staff put the watermelon in, with no attempt to explain it, to see if they had finally fatigued the executives' supervision.
 * In David Cronenberg's Dead Ringers, the less mentally stable of the twin gynecologists has invented a ghastly-looking array of bizarre surgical instruments, which we see in a brief, rather chilling scene.
 * These are reputedly the Little Shop of Horrors dentist's tools making another movie appearance.
 * The Live Action Adaptation of Inspector Gadget had Tinkertoys, a dead fish, garden hose and many other strange things alongside traditional operating tools.
 * The 'autopsy' sequence showed that he was full of apparently useless and unrelated Cow Tools.
 * Parodied in Airplane II: The Sequel, where two officers on a space station puzzle over what a particular Cow Tool is for.
 * In Ghostbusters, Venkman enters Dana's flat operating a strange device with a long tube and a rubber bulb that appears to pump air through the tube. When she asks what it does, he replies vaguely "It's... technical. One of our little toys." (Actually the device does have a purpose, Venkman just has no idea what he's doing.)
 * Monty Python's The Meaning of Life. "This is the machine that goes 'Ping'. It tells us that your baby is still alive." Somehow, it does so without being hooked up to the expectant mother.
 * The interior of the Seaview in Voyage to the Bottom of the Sea and its TV follow-up is full of random flashing lights, switches, screens, boxes, and wires that don't serve any apparent purpose. The lights are so prominent a character actually says "it's always Christmas on a submarine."
 * The film The Shape of Things to Come, fondly remembered by B-movie fans as "Blinky Blinky" due to the tons of weird machines with blinking lights in almost every scene.
 * Unexplained bits of tech are sometimes thrown in as a joke in Q's laboratory in James Bond films.
 * In The Lord of the Rings: The Return of the King, Elrond is seen fiddling with a telescope... thing.
 * Event Horizon had a medic named CJ, who was carrying a vast array of not-very-useful tools on his vest. His actor initially wanted the character to wear the items to aid in character design, but quickly found them cumbersome and irritating. No medic or paramedic would want such a strange rig; there are much more elegant solutions to keeping your gear handy and much more important gear to have within immediate reach.
 * In Predator, the Predator is injured by Mac during the More Dakka scene, and uses a variety of alien Cow Tools to patch the wound. According to the director, these are based off of actual veterinary tools.
 * Dr. Cal Meacham's lab in This Island Earth is full of random equipment.

Literature

 * In Harry Potter,, where for centuries students have been storing total junk. When he hid it, a bunch of other random stuff was there, and it's speculated whether Voldemort thought that was created by magic, or whatever, because he claimed that he was the first to find it.
 * All the insanely weird stuff in the Department of Mysteries.
 * Dumbledore's office has a variety of inventions, which he can use whenever, but which are beyond the realm of the audience's understanding.
 * Several Discworld books note that every proper wizard has a stuffed alligator hanging from the ceiling of his laboratory, even if there aren't any alligators naturally in the area. No one, especially the wizards, is sure why.
 * Also Lampshaded a few times: Archchancellor Ridcully, in a pinch and pressed for time, manages to perform the ominous Rite of Ash-Kente to summon and bind Death with two candles, an egg and some string. Wizards like all the ornamentation, though; and besides, the more difficult and complex the ritual, the less likelihood that some random idiot who doesn't really know what he's doing will try it.
 * The Department of Necromancy Post-Mortem Communications is full of dribbly candles, cobwebs, skeletons and assorted Cow Tools, because if a spirit is going to make the effort of piercing the veil and returning to the living world, a wizard ought to make the effort to see that things look right.
 * Also, nobody knows what most of the stuff hooked up to Hex actually does, including Ponder Stibbons and Adrian Turnipseed, who built the thing in the first place.
 * Although this is also because Hex has a habit of adding things all by itself!
 * The addition of Anoia, goddess of things that get stuck in drawers, to the Discworld pantheon has provided excuses for many kitchenware Cow Tools to have their inexplicable and/or useless presence in everyone's cupboards lampshaded.
 * The "offog" from Eric Frank Russells' science fiction short story "Allamagoosa." Many purposes, as well as descriptions, are put forward for this essential item of a starship's inventory....unfortunately, all of them are wrong. The ship is being inspected by Admiral Beancounter, so the pressing concern for most of the story is not what it actually is, but that they have to have one.
 * In Spider Robinson's Lady Slings The Booze, the narrator, a Private Detective specifically Lampshades the fact that in his profession, it is vitally important to be able to accurately observe and describe whatever he sees. He then enters the laboratory of the resident Mad Scientist, which he is only able to describe as "a rectangular solid filled with stuff, to his great chargin."
 * Subverted in the Niven and Pournelle work The Mote in God's Eye when the Moties present the humans with a room filled with what appear to be Cow Tools but are not. The tool room is actually an "IQ" test of sorts. The humans are expected to determine the flaw in each tool which renders it useless. Naturally the person who figures this out is the ship's engineer.
 * In The Voyage of the Dawn Treader, we see some stuff like this in Coriakin's lair. The most prominent example is the Bearded Glass, which is...well...a mirror with a beard attached. When someone passes, their reflected face looks like that of a bearded weirdo jumping out of the shadows. It may serve some purpose, or Coriakin may have simply put it there to prank what few visitors he gets. Even C. S. Lewis says he doesn't know its purpose.

Live Action TV

 * Every Mad Scientist has to have a plasma lamp, to evidently show his technological prowess, regardless of the fact that every Spencer Gifts and Circuit City in the world sells them for about $25 each. Also, some piece of machinery topped with a "Jacob's ladder" spark gap, plus flasks of colored (optionally foaming) liquid, as all mad scientists apparently dabble in chemistry by default.
 * A standard gag on many "bad movie" review sites: "Beakers of strangely colored fluids? There must be SCIENCE going on here!"
 * Many of the tubes, conduits, and access panels of the dressing the original Star Trek: The Original Series sets were labeled with the cryptic acronym GNDN to remind the stage crew that this or that prop machinery was merely for show and that it "Goes Nowhere, Does Nothing".
 * The best example are possibly the self sealing stem bolts in one episode of Deep Space Nine. It is pretty much a case of lampshading, as Jake and Nog try to make some money out of a wrong delivery that was about to land in the garbage, but only end up with more useless junk until they finally get their hands on a shipment of self sealing stem bolts. As Jake points out, neither of them has any idea what they are used for and it never gets revealed.
 * For the Star Trek mess hall, the set dressers went out to various shops and bought a bunch of unusual salt and pepper shakers. However, they were all considered too confusing for the viewer and normal looking ones were used. They got put to good use however, as they were put in the Sick Bay as futuristic medical devices.
 * Whenever a Star Trek crew member removes a panel from a wall, they're always filled with futuristic circuitry and other such Phlebotinum. At one point, they were overused so much in episodes that set decorator Jim Mees had to politely remind the writing staff that he had to build each and every panel interior, and that they cost about $1000 each. They became known internally as "Mees panels".
 * This was lampshaded decades later in Star Trek: Deep Space Nine episode "Trials and Tribble-ations" when the crew travelled back in time to the Star Trek: The Original Series TOS era. Miles O'Brien, the station's resident Techno Wizard, can't make heads or tails of the circuitry behind the Mees panel (Keep in mind this is the same guy that can very adeptly Techno Babble his way through solving just about anything). When he encounters a real Enterprise engineer and screws up his "repair work," Dr. Bashir has to bail him out by claiming O'Brien is suffering from work-related stress and ushering him off to sickbay.
 * Lampshaded by a joke in Airplane II: The Sequel, where William Shatner's character is annoyed by a big fancy machine looking like something out of Star Trek that doesn't actually do anything.
 * It didn't just look like something out of Star Trek, it was something out of it - it's the same blinking tube device from Star Trek II.
 * Subverted with the Shelves of Honor on The Colbert Report. The shelves full of apparently random junk that line one wall of the set might be expected to be Cow Tools, but just about everything on there has some significance. See Wikiality's detailed analysis.
 * Sam's lab in Stargate SG-1 includes some things that are supposedly alien technology she's analyzing. Some of it has an obvious purpose, some of it is from previous episodes, but most of it is completely random.
 * Turned around in one episode where an alien, who's lost his memory, is working on a TV show and one of his actual alien devices is being used as a Cow Tools prop in the show.
 * Discussed in the DVD commentary for the Doctor Who serial The Caves of Androzani, when a man gets his head shoved in between two parts of a futuristic machine thing which immediately starts glowing. The serial's director notes that "we don't know what it does, but it's killing him".
 * From the newer episode, "Blink": "Tracked you down with this. This is my timey-wimey detector. Goes ding when there's stuff. Also, it can boil an egg at 30 paces. Whether you want it to or not, actually, so I've learned to stay away from hens. It's not pretty when they blow."
 * More generally, the TARDIS. It's always had way more buttons, knobs, levers, and random knickknacks than they ever actually use or have any kind of meaning for, but in recent years, the main console has gone so far as to include illogically placed bits and pieces of just about every kind of household objects imaginable, including for instance most of a typewriter with no ribbon or paper.
 * The Adventure Game series had the interesting but unenviable task of actually explaining what everything on the TARDIS console does. They should get a medal.
 * "Broken. Broken. Hair dryer..." One has to wonder what the others would have done if they'd been working (Cow Weapons?).
 * In Babylon 5, maintenance extras regularly walk around pointing vaguely cleaner-like or metal-detector-like gadgets at the floor. In A View From The Gallery two of them even speculate on what they are for.
 * Lampshaded, used straight and subverted in the laboratory where Galina Sergeivna works in the Russian comedy Daddy's Daughters. Often they will be doing serious work, sometimes brewing tea or vodka. but most of the time it is just bubbling water colors.
 * MythBusters has the real special effects studio M-5 as their base of operations, with all sorts of equipment that comes in handy for testing myths. The shop itself is constantly cluttered with devices, tools and a wall of cubby shelves with interesting labels that are more or less accurate ("Raw Meat" is one in particular that we hope is less). At one point trying to do a scale test, they needed an action figure and after a minute Jamie produced one from one of the cubbies. At other points devices from past and upcoming episodes can be seen in the background. Props from other films the studio has worked on are also around.
 * In The Red Green Show, junk-store owner Dalton Humphrey finds an odd looking device in his garage, and has to resist the male urge to keep it until he figures out what it's for.
 * Lots of the items stocked at Obscura, the weird antiques shop on Oddities, consist of gadgets that probably qualified as Cow Tools even when they were brand-new, and certainly do now that they're long-obsolete.

Music
"It went "Zip!" when it moved And "Pop!" when it stopped And "Whirr!" when it stood still. I never knew just what it was ''And I guess I never will."
 * "The Marvellous Toy", written by Tom Paxton and most famously performed by Peter, Paul and Mary, is about a Cow Toy:

Newspaper Comics

 * The Far Side: Although Gary Larson claims that the reaction surrounding the Trope Namer will haunt him until the day he dies, it actually generated a lot of positive publicity for the strip and may even have boosted its circulation.
 * There were a few other Far Side cartoons involving these. In one, gangsters torturing a hostage bring out what they call "Mr. Thingy," which looks like a fishing rod attached to a bicycle horn with a carrot on the string. In another, "Harold finds his purpose," a man digging around the couch finds a ball with springs coming off of it, including one with a duck's head attached. Larson has stated that after the controversy over "Cow Tools," he was afraid people would overanalyze these ones.

Tabletop Games

 * The Dungeons & Dragons Second Edition supplement Arms & Equipment Guide included a description of tinker gnome "armor", a full suit of leather with so many assorted Cow Tools affixed to its every surface that it functioned like studded leather armor.

Video Games

 * These are all over the place in Baten Kaitos.
 * The alien bases in the X-COM games are stuffed with these. Seizing said bases (or sufficiently equipped alien craft) even nets you research angles revolving around the insidious uses of the devices, (useless as they may be to humans). Heck, some of them are even literal Cow Tools (either for use on cows, or made out of cows).
 * Both Dr. Kleiner's and Dr. Vance's labs in Half Life 2. The former has a working mini-teleporter among the other seemingly random devices. The latter has a strange machine that sends visible rays through an object (possibly another Xen sample) which can be rotated with the controls on the panel, although nothing really happens. This is made even more strange by the fact that, during the lengthy break in action where you're expected to explore the lab, Dr. Vance specifically invites you to have a look at it, as if it were something important.
 * It's a miniature of the "Resonance Cascade" effect from the first game. Since Gordon was actually in the test chamber when it happened, it makes sense to expect him to be interested.
 * Watermelons also appear in the oddest places. A Buckaroo Banzai homage?
 * Fallout's Mothership Zeta. The shelves of the interior corridors of the titular ship from Fallout 3's final expansion are adorned with all varieties of Cow Tools.
 * The whole game really does this. There's tons of junk items lying around that serve no real purpose other than atmosphere. (Of course, if you're a good player, you'll quickly learn to pick out the Vendor Trash among them)
 * In The Official Book Of King's Quest, the hints section for the first game notes that the rusted pump and axe outside the woodcutter's cottage were "put there by evil animators trying to drive you crazy figuring out what to do with them".
 * In King's Quest V there is a strange astronomical-looking device outside Crispin's house, which is one of the first things in the game that you're likely to see. It serves no purpose whatsoever, and your annoying sidekick warns you not to touch it.
 * Toyed with in King's Quest VI. The Pawn Shop has dozens of bizarre items on the shelves that you can look at but not buy. If you look at them, the narration will identify things like "whale tongue climbing gear" and a "bridge repair kit". The joke is that these are all things which would have been immensely useful in earlier games but are completely useless in this one.
 * The Myst series and its sequels has plenty of these. Most of the time you can puzzle out the various tools that Atrus and Gehn have lying around, but many of the other things are a mystery. On the other hand, sometimes a seemingly-innocuous doodad will prove to be a vital clue.
 * The Hitchhiker's Guide to the Galaxy had the "Thing Your Aunt Gave You that You Don't Know What it Is."
 * The Geneforge series is littered with Vendor Trash generically described as "Shaper Equipment" and exotic looking props, some of which can be interacted with a "that's not important" Hand Wave. Presumably the characters know what they are; whether the player is ever informed draws the line between Cow Tools and MacGuffin.
 * Sigil in Planescape: Torment is jam-packed with odd-looking buildings, twisted sculptures, and bizarre devices that you have no idea what they're for. You can click on them to get a description. Many of them will then say "You have no idea what this is for."
 * On the other hand, there is a shop filled with bizarrely-described items, almost all of which turn out to be crucial plot tokens. (Just not the baby oil made from real babies.)
 * Lots of old platformers (but especially Mega Man) have many, many levels in labs and power-stations and so on; the walls are always covered in computer-buttons, giant gears, and in general, anything science-y looking, since how else would you know you were in the future?
 * Lots of old platformers (but especially Mega Man) have many, many levels in labs and power-stations and so on; the walls are always covered in computer-buttons, giant gears, and in general, anything science-y looking, since how else would you know you were in the future?

Web Comics

 * Girl Genius, set in a world ruled by Mad Science, is, of course, full of these. Notable examples in Gil's Lab and the handy circus repair kit.
 * Which would have come in handy in a previous storyline.
 * Not exclusively Cow Tools, mind.
 * In the webcomic Oglaf, the Mistress' torture implements here and here. (Warning: NSFW)
 * Sandra and Woo's strip Coon Tools is a raccoon-related variant of the original cartoon.
 * In the defunct web comic Commedia 2X00, Lord only knows what half the stuff in Dottore's lab do; he's got a jukebox that plays Wagner to help him think, but that's about it. The storage-boxes in the background when Columbina goes to the storage basement are full out shout-outs to famous technobabble, including turbo-encabulators, blinkenlights, and vgrep scanners.

Western Animation
"Cheetara: What is all this? Lion-O: It's what's out there, beyond Thundera's walls...what the Book of Omens calls "technology.""
 * Danny Phantom where a couple of Jack Fenton's invented ghost weaponry are so oddly shaped or out of place that one wonders what the blinding hell they do exactly. His wife pointed out a similar reason in one episode.
 * Dexter's Laboratory is the king of this trope, featuring an enormous variety of technological inventions in Dexter's lab that are never explained and their use is never revealed. Many times, Dexter will be seen working on a particular gizmo (almost always by simply tweaking it with a wrench) that very, very rarely has any importance in the plot.
 * Lampshaded by one commercial for the show, that showed a loop of Dexter using his wrench on said gizmo for several seconds before the narrator says "Y'know, eventually, he's got to overtighten that thing."
 * Another good example is Merlin's cottage in Disney's The Sword in the Stone. It's full of little gizmos and gadgets Merlin is said to have acquired from the future. Some, like a globe, a model of the solar system, and vehicles like trains and biplanes, can be recognized. The rest are simply eye candy.
 * Or maybe they are from so far in the future our present hasn't caught up to them yet and we won't know what they do until it does.
 * Basil of Baker Street has a lot of these lying around his flat in The Great Mouse Detective. Most have a fairly easily discernible purpose, though - for example devices for producing cigarette ash and footprints for analysis.
 * In Batman Beyond: Return of the Joker, during the flashback to the Joker's death, there's a shot of some innocent junk lying around (a toilet plunger, for example). Word of God says originally Joker's tray was originally going to have bloody surgical instruments but the execs put their foot down.
 * In the 2011 ThunderCats, Lion-O introduces new friend Cheetara to the shop of Jorma, his Friend in the Black Market. His shop is stuffed with oddball wares, including a Chekhov's Gun Black Box, and an arm from a race of Cute Machines introduced later.

Real Life

 * Those annoying flashing blue lights on Netgear routers. You know what they are.
 * Half the buttons on any given remote control.
 * Any place where tools, spare parts or electronic equipment is stored will have a few of these. Slightly subverted in that all of it clearly had a vital function at some point, but it hasn't been needed in quite some time and nobody can quite recall what it was originally used for.
