"Fetch me old red doubletCharacters who have a tendency to receive horrible injuries also tend to wear red. Perhaps this is some bizarre permutation of the Red Shirt effect, warped slightly by Contractual Immortality. Perhaps some otherworldly fashion deity has declared that anyone likely to be spattered with blood must wear complementing shades of scarlet. Or perhaps it is the censors wanting to keep the carnage from standing out more. Whatever the reason, it sometimes seems as though all a guy has to do to get his arm hacked off is stand near some red drapes. And woe be to one of those guys if he ever comes near a bullfighting stadium... The trope name comes from an old joke: the captain of a ship always asks for his red jacket before a battle, so his crew won't see him bleed and therefore lose morale. The punchline supplies the name for Bring My Brown Pants. Red is also a dangerous color for young girls to wear — older girls, however, are more likely dangerous themselves. Compare Red Shirt, White Shirt of Death, Red Is Heroic. Probably works better with Rustproof Blood than the real thing.
Bring it to me now
I'll wear it in the rigging when they fire across the bow
Fetch me old red doublet
That's all the luck we'll need
Even if they shoot me down they'll never see me bleed!"

Anime & Manga
- Played with in Cheeky Angel, where the school bad boy wears a black shirt, against code, because he gets in a ton of fights and blood won't show on black.
- In Japan, red is the traditional color of the hero. Many of these heroes fit the red formula in the Red Oni, Blue Oni duo, as well as highlighting their usual fiery spirit.
- Alucard of Hellsing and Vash of Trigun both practically personify the trope; although in the case of Trigun, Wolfwood doesn't fare much better in his black suit and white shirt. Hell, Alucard has the primary battle tactic of letting his opponent tear him to shreds.
- Inuyasha: In his completely red outfit, Inuyasha is not particularly lucky, and despite (because of?) his demonic resilience, Kagome practically has to duct tape him back together after many battles, including once having a punch go through his abdomen and out the other side. His brother, Sesshomaru, provoked the mutilation gods merely by having a few red stripes on his clothing, and subsequently lost an arm. The censor potential is especially notable here, as blood seems darker on dark-suited folks. In fact, the movies have less strict censorship rules than the anime, and the blood is red rather than mostly black, so his injuries seem less stark than in the regular series. In certain cases, it's actually difficult to tell if he's been injured or not. You know, except on general principles.
- It gets better: That red outfit is his armor. In addition to reducing damage from physical attacks, it's also fireproof.
- Ranma Ĺ: The same goes for the titular character in Takahashi's previous work in a red shirt, Ranma Saotome, but in a more comedic manner.
- In the climax of the Kurosawa-based Samurai 7, Kyuzo's violent, extremely ironic death was probably the result of his signature crimson Badass Longcoat.
- Gareki from Karneval wears one of these, underneath which is a pretty slutty shirt. A worse offender than the usual is seen on the cover here◊, but no one (except the readers) has bothered to point it out yet.
- Vita of Lyrical Nanoha has red hair, a red hat, and a very red dress. Guess who spent most of Magical Girl Lyrical Nanoha StrikerS' last mission bleeding all over the place and had a tendency to get wounded even before that?
- Van from Vision of Escaflowne fits this trope to a T. Look no further than episode 14 as an example.
- Chrono from Chrono Crusade wears a red coat and red shorts, and true to the trope, he's constantly getting injured, particularly in the manga. In the manga, he loses one of his arms at least three times. (Of course, as a demon, he has the power to heal his wounds...which is part of the reason why he feels like he can put himself in so much danger.)
- Kusanagi Mamoru from Blue Seed. His trademark outfit is a red coat, and boy does he tend to get injured and even (apparently) die on occasion — though it's usually not a big deal. One little problem with the red coat is that it only makes his injuries more visible, because his blood is green...
- Asuka in Neon Genesis Evangelion wears a red plugsuit and has red hair. She is the one that gets the most severe injuries out of all of the pilots. Asuka gets to feel the pain of being impaled through the eye, eaten alive, arm cut in half, and finally impaled through her arm, head (again), and torso with 9 spears, all at 300% strength (her sync rate of 300 made her feel everything three times stronger than reality.)
The same goes for her red mech, Unit 02, which, in one battle, had both arms and its head cut off, while, in The Movie, it was wrecked up in a manner so graphic it's only rivaled by the destruction of Unit 03, piloted by Toji.
- It's implied that Asuka's sync rate is so high in End of Evangelion that anything that happens to her Eva actually physically happens to her as well. As seen when her arm seemingly spontaneously splits in half just as her Eva is speared by the MP Evas.
- The trope also applies to Misato, who wears a red jacket and is the only main character to be killed in the JSSDF's raid in End of Evangelion, as she is fatally shot, and, before she can succumb from her injuries, blown up.
- One Piece
- Shanks depending on who does the coloring, has either a red or black cape. Subverted as he threw it off to swim out to save Luffy, and then lost his arm.
- Luffy fits too, with his standard red shirt. And boy, does he get beat up.
- Ed from Fullmetal Alchemist has his standard red duster. On the evening before the final battle, he purchases a bunch of red fabric and replaces it because his old one got torn up after he went north. His reasons for wearing red is that red is a Badass color or he reckons it psyches his mind. It doesn't do much to hide wounds, though, seeing as almost every time he's in a major fight, at least part of his shirt comes off.
- Rurouni Kenshin -
- Kenshin wears a red kimono (and pretty much only that one kimono) throughout the series. However, he's portrayed as wearing blue in flashbacks when he was an assassin.
- Sanosuke wears an iconic red headband. Unsurprisingly, he gets a lot of head injuries whether by being punched in the head or head-butting someone else.
- In Black Butler, Madam Red not only wears a red cloak, but the colour red makes up her a major part of her backstory. So does Grell while in shinigami form and it is a major part of her character as well. After Madam Red's death, she even takes the cloak from her, saying "You're not fit to wear the color red."
- Blood+: After the Time Skip, Saya, perhaps having grown into her Blood Is the New Black/Blood-Splattered Warrior tendencies, starts wearing a dark red, almost maroon leather coat.
- Ban from The Seven Deadly Sins is an immortal that is often subjugated to all sorts of bloody wounds that he can just simply heal from. Fittingly, his standard attire is predominately red.
- Advice And Trust: Red-suited Asuka's fights are bloody, and she usually gets hurt or worse. When Leliel swallowed her giant robot whole, she ripped it apart from within, and its blood bathed her mecha. When the pilots fought Bardiel she got the worst injuries and she felt the pain of getting your arm ripped off when her robot lost its limb.
- Evangelion 303: Asuka wears a red pilot suit. Her experimental jet fighter crashed and she was several months in a coma. She is also the only main character who has been seen hurt, wounded and bleeding in the first arcs.
- Once More with Feeling: Shinji often reminds what Asuka -who always wore red- got worse wounds than Rei or himself during the battles, and she got killed in the most gruesome, bloodiest way.
- Thousand Shinji: Asuka always wears red (and she's capable of transforming into a red-skinned devil). Her battles are the bloodiest of all: either she hacks her adversaries apart, or her adversaries hack her apart.
- In Asuka's first engagement in Children of an Elder God, an Eldritch Abomination ripped her mecha's hand off. In reaction, she beat it to a bloody pulp, smearing her robot and the battlefield with its blood. Her next battles were similarly bloody.
- In The Second Try, Asuka usually took the brunt of the fights due to her aggressive fighting style, and her red mecha was maimed in nearly every battle: Zeruel loped Unit-02 head's off, Tabris cut its hands off, the MP-Evas nearly ate her alive again...
- In an interesting color inversion, Nausicaa (of Nausicaš of the Valley of the Wind) goes into the last part of the movie wearing a red dress, which is then dyed blue from being soaked in blue Ohmu blood.
- Haldir in the movie version of The Two Towers wears red to the battle of Helm's Deep. This battle proves to be his last.
- The Spirit. "Somebody get me a tie — and it sure as hell better be red!"
- The distinctive red uniforms of the Star Trek: The Original Series, cast worn throughout Star Trek II to Star Trek VI, technically making every character a Red Shirt.
- Rebel Without a Cause: Jim wears the iconic red jacket for most of the film, but lends it to Plato shortly before the latter is killed. When Jim's father arrives on the scene, he recognizes the jacket and thinks it's his son who's been shot.
- Ultraviolet: when the titular character receives a gash on her hand, her colour-changing clothes immediately change to red.
- In Hero, the most violent version of the story uses red as the main colour.
- In Schindler's List, a little girl in a red jacketnote is seen at the ghetto. Later in the movie, Schindler sees her corpse about to be burned.
- In the Silent Hill movie, Rose's outfit starts out in light spring colors, fading to duller and duller shades throughout the movie, then turning blood red for the climax.
- Lampshaded in Deadpool as our hero is attempting to scrub his blood out of a white hoodie at a laundromat. Blind Al suggests he wear red instead.
- The palace guard in The Scorpion King wore red outfits.
- In one scene in Pee-wee's Big Adventure, Simone's jealous boyfriend Andy chases the protagonist into a rodeo. Unfortunately for Andy, he's seen by a bull, and he's wearing a red shirt; cue Oh Crap! expression when he realizes how bulls react to the color red...
- In Terry Goodkind's Sword of Truth series, the Mord-Sith are female torturer/bodyguards who have color coded outfits. Usually, they wear plain brown leather. When they switch to a red outfit, that's when they mean business. They also have a white outfit, which symbolizes when a Mord-Sith has "trained" (read: tortured and broken) her pet so well that she doesn't need to coerce him into anything. This particular outfit shows up twice; once in the first book, where the main character is the pet, and once in the last book, when one of the Mord-Sith gets married. Either Goodkind was just going for a white outfit or he was trying to say something...
- In Hero by Perry Moore, Ruth is stabbed through the stomach - BY A TREE BRANCH - but it takes Thom and Scarlett a minute to figure out that she's dying, thanks to her red dress.
- A young Richard Bolitho (from the novels by Alexander Kent) wonders why his captain wears a red coat before a battle. Needless to say, he finds out.
- One of the children's spinoff books based on Cluedo had Miss Scarlet being identified for an accidental stabbing because she was the only one who had clothes she could use to wipe the blood off her knife.
- Occurs in Witch by Christopher Pike. Julia has a vision of Jim dying in a gas station, and his red jacket is very prominent in the vision.
- The Eastern Empire from the later Heralds of Valdemar books issues dull red uniforms to its army. The joke in that army is that the color was chosen to cut down on cleaning bills post-battle.
- Averted by the Bards of Valdemar, who also wear red uniforms. Thanks to their Bardic Immunity, it's against the law to harm them, and the relatively few major Bard characters tend to avoid suffering the same degree of trauma that other characters - including the white-clad Heralds - are prone to.
- In a subversion, Anita Blake prefers black clothes while working, because she finds that black hides the blood even better than red.
- In The Wise Man's Fear, Adem mercenaries prefer to wear bright red. Kvothe guesses this is so their enemies will not see them bleed. In contrast, Shehyn, an Adem master, wears white, because she does not bleed in battle, and if she ever did, seeing her bleed would be her enemy's rightful reward.
- In Cerberon, Aladavan is wearing a red jacket when he's nearly disemboweled by a skraad. He comments on this fact and is amazed that his white trousers didn't get bloody.
- Averted in All You Need Is Kill. The Full Metal Bitch wears red Powered Armor, but she's famous for never having a scratch on it. It's meant as inspiration for her fellow soldiers and also to draw the attention of the enemy.
- Mal Reynolds of Firefly wears mostly earth tones, including brown and red. These clothes are frequently ripped and torn, mostly by bullets and knives. Occasionally, this color scheme is the direct cause of some of Mal's injuries — like when he wears it into an Alliance-friendly bar on Unification Day and picks a fight. Mal wearing red is played with in the side comic book story Serenity: Those Left Behind. In the comic, River comments that she hates the color red on Mal, which is an ironic throwback to the episode "Ariel" in which she cuts Jayne with a butcher knife and then comments that he looks better in red. River's comment is very likely intended to suggest that Mal does this trope on purpose for the reason given in the page quote. River may or may not like Jayne, but definitely didn't like the Blue Sun shirt he was wearing, and slashing him was the best way she came up with to get him and the shirt to go away.
- In Star Trek: The Original Series, Red Shirts are famous for guaranteed deaths. (Scotty and Uhura excepted.) Scotty was killed by the probe NOMAD in "The Changeling". He got better.
- In Star Trek: The Next Generation, the Starfleet uniform colors are inverted; Red Shirts are now command and main characters while the security and engineering staff wear gold. They don't often die, but they do get tortured, maimed, shocked, or have the shit kicked out of them.
- The miniseries adaptation of Tony Kushner's Angels In America puts long-suffering AIDS patient Prior in a red robe when he goes to Heaven, with a stylistic nod to Schindler's List thrown in by having the red robe the only thing in color through that part of the sequence.
- In Heroes, Claire Bennett's season one cheerleading uniform was mostly red, for good reason.
- In Legend of the Seeker (see Sword of Truth), the Mord-Sith only wore the red version of their outfit at first, with no explanation given, but an episode in the second season finally showed off the white leather, along with an explanation of what it meant.
- In Degrassi, Campbell wears a red team sweatshirt on the day he commits suicide.
- In Daredevil, young Matt Murdock hears that his father's robe for the boxing ring is very red. He mentions the advantage.
- The Spanish Civil War song "Tengo la camisa roja" ("I have my shirt in red"), in which a soldier tells others that he's covered in the blood of his deceased partner.
- This was a complaint launched at the first blood match where "Stone Cold" Steve Austin lost the WWF Championship to Kane. Not only was Kane clothed head to toe, exposing no skin, but he wore red(this trope) and black (which doesn't change color much at all), making it very difficulty to tell if Kane had started bleeding first or not.
- The eponymous character in Captain Scarlet and the Mysterons.
- Warhammer 40,000, presents us with Khorne, god of war that values spilling blood pretty much above anything else. His daemons have red skin and troops that worship him tend to wear dark red armor. All of them are best employed in close combat assaults.
- Loyalists have Blood Angels, a noble legion that has a genetic flaw, extreme case of bloodthirstiness. They are also regarded as the best shock assault troops in the Imperium. Their chapter colors are mostly bright red.
- To a lesser degree, Fire Dragons aspect warriors. They employ extremely powerful, but short range weapons, which means they are expected to be shot and take losses unlike most of Eldar troops. They tend to wear reddish armor.
- Farsight enclave of Tau have red armor as well and unlike the rest of Tau Empire, they do train in close quarter fighting. It helps them conserve ammunition when faced with their most frequent enemy, orks. Their leader is even semi-good at this.
- Ada Wong of the Resident Evil series always wears at least a red shirt or a red dress, though she rarely suffers severe injuries (except for her Not Quite Dead moment in Resident Evil 2).
- Dante of the Devil May Cry series wears a Badass Longcoat of an almost garishly blood-crimson color. He does have a tendency to suffer atrocious levels of injury — often with his own weaponry — but it almost never slows him down for long. Part of this is due to Cutscene Power to the Max, wherein Dante is a practically unkillable warrior, and the other part is due to his demonic heritage.
- From the Final Fantasy series
- The Red Mages. Though they usually are less of Squishy Wizards than Black or White ones due to being able to equip better gear.
- Final Fantasy IX Freya Crescent is also dressed in red, though she's a Dragoon rather than a Red Mage. Something of an aversion, since Freya's Jump ability means she tends to avoid getting hurt. Except emotionally of course, but then this is Final Fantasy IX we're talking about.
- Auron in Final Fantasy X seems like an exception, in that his blood-red longcoat doesn't accompany any particular hardship in the quest. But then, he's already dead to begin with.
- Ditto for Vincent Valentine in Dirge of Cerberus - when he sustains a major wound, it closes up right away.
- Lemon, the "Red Baron" from Shining Force 2, wears a deep red suit of armor. It is rumored that the red color comes from the blood of all the enemies he has slain. When he is turned into a vampire, he attempts to kill himself in several ways (because Who Wants to Live Forever?).
- In Tales of Symphonia, the party goes to the king of Tethe'alla to discuss the present situation. After making their case, they are sent to the "Crimson Room", where they keep visitors they're not sure what to do with. The implication is that should they decide to kill said guests, the all-red decor in the room will hide the bloodstains better.
- In Shadow Hearts: From the New World, Killer, who sports red pants and hair, seems to sustain near-fatal injuries on a regular basis. Interestingly enough, he actually does die after the boss fight in which he transforms into an all-red dragon.
- Ragna, the protagonist of BlazBlue, wears a red coat and also has horrible defense. In addition, several of the Multiple Endings end with him dying or worse.
- Mega Man X and Mega Man Zero's all-red Zero has a (somewhat fan exaggerated) reputation for getting heavily injured and even killed. This extends to his playstyle as well, being a Glass Cannon who gets up to his enemies and slashes them.
- Sissel from Ghost Trick wears a red suit, and starts off dead. However, it gets a bit complicated as in reality, Sissel mistook the corpse of his owner, Yomiel, for his own and is actually a black cat wearing a red neckerchief. Yomiel meanwhile, was 'killed' ten year prior by a fragment of the Temsik meteorite, and as a result cannot feel pain, or be killed, meaning that he can get shot and slapped around a fair bit with no actual damage.
- Leviathan in Hard Corps: Uprising.
- Not characters, but ships: In RefleX, both the Phoenix and the (human-made Virgo) are red-colored. Both ships are totaled in Area 7. The latter's pilot manages to escape somehow. Unfortunately, the former's pilot dies...although said ship then comes back controlled by an AI and beats the shit out of the boss that murdered it.
- Umineko: When They Cry - Battler Ushiromiya manages to suffer from a double dose of this trope - red shirt, white jacket. He's also the only one who never simply dies, oh no, he dies and then is resurrected to be killed over and over again. In the end, though, it turns out that he's one of only two people who actually survived the events on Rokkenjima.
- The school uniform in Kanon is red. Mai, the Emotionless Girl that swordfights with demons, sustains life-threatening injuries in her uniform, with accompanying red stains. However, in the ball scene, where nobody is wearing red, people are fiercely attacked and, in some cases, badly hurt, but nobody bleeds. In the SUV scene, the victim isn't even shown, and replaced in the remake with the red stain of a strawberry dropped on the ground.
- Fate/stay night - Rin Tohsaka wears red in all of her outfits (except her sleepclothes), but it's pretty much a subversion, because the one time you see her seriously wounded, her blood isn't just on her, it's everywhere.
- Bangaladesh Dupree from Girl Genius tends to wear a red sweater, although its almost never her blood that gets splattered on it.
- Late in the fourth act of Homestuck, an alternate future version of resident Bad Ass Dave Strider is found dead in a red tuxedo. Earlier on, in the Midnight Crew Intermission, this is inverted: the antagonists, a pool-themed Gang of Hats called The Felt, are dressed in entriely in green and have green skin. The blood is quite vividly noticeable.
- In Last Res0rt, in what's either an incredible bit of foreshadowing (or just poor costume design on Nate's part), Andromeda's uniforms are light blue with red stripes crisscrossing over approximately the left side of the abdomen. Guess where Jason shoots her as soon as he gets the chance.
- Daisy also uses red to her advantage, however — the red ascot she wears as part of her uniform is because she wants to hide Jigsaw's vampire bites, and she even hides a vial of Jigsaw's vampire blood inside her hairdo — did we mention she's a redhead? — to keep herself alive after said shooting from Jason.
- Aquaman in the Justice League cartoon. He and his baby were tied to a Death Trap. He managed to return back to his castle with the baby, but the baby wasn't wrapped in red cloth anymore. Cue the reveal of the wrapping around his handless arm.
- Zapp Brannigan of Futurama considers red velour the best choice of military uniform. (But, for some reason, also no pants.)
- Supposedly, soldiers dressed in red tended to have higher morale and inspire greater fear in their enemies.
- The Romans, being one of the first to practice this for their military dress, did so because their soldiers would be less likely to see their own blood upon injury and thus become demoralized.
- Even before the Romans, the Spartan army dressed in crimson, supposedly because crimson garments were seen as bearing "the least resemblance to women's clothing."
- The Knights Hospitaller, or Knights of St. John. Their field uniform was (and still is) a red surcoat with a large white Maltese cross. The red surcoat may be worn only at the combat zone; elsewhere, a black surcoat with white Maltese cross is to be worn.
- The British army from the 17th to 19th century were famously known as "redcoats" due to their uniform. The common belief was that this was to hide blood stains. Other theories for why the colour was used are:
- The bright colours were simply to enable a soldier to distinguish friend and foe easily in the heat of battle. (Which has both benefits and drawbacks.)
- The use of red for the majority of infantry dates back to England's New Model Army in 1645, though some units used it beforehand. Some sources have it that Cromwell wanted blue, but red was cheaper and/or the only colour available in the quantities needed. Interestingly, because of this use of cheap natural dyes, the average soldier's field uniform would rapidly fade to a muddy maroon shade rather than the 'factory fresh' red inevitably seen in fiction.
- The colloquialism "redcoat" only dates back to the 19th century; they were called "the King's men" by the American rebels.
- One of the more widely accepted theories among historians (who, it should be noted, scoff at the aforementioned blood stain theory) comes from the fact that during most of this period, the British army was world-renowned for being one of the best and most well-trained armies in the world. Since the range and accuracy of muskets at the time rendered stealth and modern guerrilla-like tactics meaningless, there was little reason not to flaunt your reputation to intimidate your opponents.
- Unfortunately, the red dye and the fabric used was of abysmal quality, so after a few months in the field the English would look bizarre: the red jackets would have run, leaving them a kind of anemic pink, whilst the dye would have stained the white breeches, making it look like the soldiers had wet themselves whilst pissing blood (for which reason most soldiers in the field tried to source new attire; cavalry breeches were preferred), and added to all that there would be the various scraps of cloth used to patch uniforms.
- Napoleon wore a red shirt in battle, supposedly to never let the enemy see him bleed.
- According to that other wiki, Confederate general A. P. Hill had a red "battle shirt". He was never seriously injured so long as he wore the red plaid shirt, making it a subversion of Bring My Red Jacket and Red Shirt, as well as being a combination of Contractual Immortality and The Lady's Favour, since it was given to him by his wife, who said "As long as you wear this, you'll come home to me.". He died the only time he didn't wear it into battle, at Petersburg.
- Giuseppe Garibaldi, an important player in the unification of Italy in the 19th century, led redshirts (not that kind) to battle. Some legends say he was inspired by butchers using the blood-hiding aspect, but The Other Wiki notes this is unlikely.
- Similarly, the gun decks of men of war in the Age of Sail were customarily painted red to lessen the shock of seeing the copious amounts of blood that covered them in battle. It was also cheap.
- Yamagata Masakage, one of the Takeda clan's 24 generals, was known for his men's red armor. The Takeda cavalry was known throughout Japan during the Sengoku era as being the finest.
- A later general serving under Tokugawa Ieyasu, Ii Naomasa, would later adopt this, outfitting his own units (both cavalry and infantry) with red armor, gaining them the nickname the "Red Devils". Naomasa himself would have the reputation of surviving countless battles with multiple injuries.
- In sports, red shirts are a popular choice. In football/soccer, at least two teams are nicknamed "Red Devils" (Manchester United and Belgium); England has it as secondary uniform, and since their only FIFA World Cup was won with a red kit, it's used for special occasions; and in a not-very-successful attempt, Germany used red for 4 years as a secondary kit in an attempt to intimidate (it has since been changed to black). Conversely, in college American football, to be a 'redshirt' means to be put on the practice squad for a year. The reason for this is to get better while retaining a year of eligibility of play.
- Redcaps were named for their red caps. The red came from the blood of people they killed, which they did often, since the red would eventually fade.
- On U.S. aircraft carriers, flight deck crew wear different colors to denote their jobs. Those wearing red shirts handle ordnance.
- Which also brings to mind the other Red Shirts as well, since anything ordnance-related is on their shoulders. In the event of fire, part of their task is to get rid of any ordnance on the flight/hangar deck, dumping it overboard while other members of the crew spray the plane down with water and foam. If the ordnance detonates before they can get it away safely, they're the first to buy the farm... but within a few microseconds, so is everyone else in the blast radius.
- At least one Japanese commander in World War II was on record for wearing a red shirt specifically to hide any wounds he might sustain on the field, lest his men become demoralized by the sight of their commander bleeding to death.
- In revolutionary France, it was recommended that a guillotine be painted red, so as to make the sight of a person being beheaded slightly less gruesome.
- As freshly-shed human blood actually comes in two shades, bright scarlet for oxygenated and reddish-maroon for deoxygenated, it's questionable how well a wounded person's blood would actually blend in with any given shade of red fabric. Once it dries, of course, it'll turn brownish and stand out anyway.
- Despite the quip in the description, this trope is the reason why matadors' capes are red: to mask the bull's (or the bullfighter's) blood from spectators. The color of the cape isn't why bulls charge; it's more the fact that he's waving it at all (and the bull has already been enraged by tiny but painful cuts before the bullfight, of course...)
