Sheldon: If we were an old married couple, the wife would serve iced tea and snickerdoodles.
Penny: I don't have iced tea and snickerdoodles.
Sheldon: A good wife would go to the store.
Penny: I want a divorce.
Sheldon: Good, on the way to the lawyers pick up some tea and cookies.
Two characters who seem very comfortable with each other to the point that it seems like they have been married for a long time, though obviously it doesn't apply to couples who actually have been together for a long time. Usually it is done through constant arguments with each other, as only people who are so closely bonded can have such open communication between them (whether they will admit it or not). Someone is apt to comment that they behave just like a married couple.
Typically the argument will be a back and forth of opinions, such as a Cavemen vs. Astronauts Debate. It is likely to get heated but neither of them are willing to just leave. In extreme cases it might start getting ugly with insults about personal issues being flung about. If not an argument based, it is often tied with Heterosexual Life-Partners where domestic issues are a common topic. The two bickering characters in question do not have to be romantically involved with each other as the trope can apply to any two individuals such as best friends, siblings, military comrades, and a couple of strangers who don't know much about each other and are not romantically or sexually involved but their situations make them bicker as if they knew each other for a long time
Often applied to those with Belligerent Sexual Tension and Unresolved Sexual Tension. Compare Slap-Slap-Kiss. When this leads to an outsider concluding that they're really a couple, one of them will say "She Is Not My Girlfriend". See also Vitriolic Best Buds. Can be a staple of having characters be Mistaken for Gay by way of adding to the Ho Yay-derived humor.
- Captain America and Iron Man, throughout almost all of their friendship.
- On a totally different note, Lewis Trondheim's Kaput & Zösky.
- Booster Gold used the phrase (in #36 of his ongoing title) to describe his own relationship with Blue Beetle (Ted Kord), after Vril Dox II assumed they were lovers. (This was rather a broad-minded assumption on Vril's part, but only because Ted had been transformed into a chipmunk at the time).
- Wolverine and Nightcrawler act as a married couple and parents, sometimes for Kitty and Piotr (with Dad-Wolverine being hard when Piotr hurts Kitty or wishing that his "daughter" remains on the team)
- Bone gives us the Two Stupid Rat Creatures, Smelly and Stinky. Pretty much every time they appear they spend most of their panel time bickering with each other like idiots. The fact that one of them is hopelessly determined to eat a quiche dosen't help.
Purple Rat: If we keep him for ourselves we can do whatever we want with him.
Brown Rat: Does that include baking him into a quiche?
Purple Rat: NO, IT DOES NOT INCLUDE THAT!
- In their neverending quest to include as many Ho Yay tropes as they possibly can without kissing on-panel, Professor X and Magneto spend seemingly more time doing this than they do actually battling.
Magneto: I generated a pocket wormhole.
Professor X: I don't believe this. I leave you alone for barely a night...
- In Calvin and Hobbes, Susie's fantasy sequences depict her and Calvin as an old married couple. Their arguments tend towards utter ridiculousness, since Calvin insists on acting like the immature six-year-old he really is.
- Used in a deleted scene of The Princess and the Frog, between Naveen and Tiana.
- In Strange Magic, late in the film the fairy knight Roland realizes that his ex-fiancée the fairy princess Marianne and the seemingly "evil" Bog King have fallen in love because they start arguing like a couple. He says in a very shocked way "Are you actually having... a lover's tiff?"
- Finding Dory has Destiny and Bailey, a pair of "neighbours" who frequently bickers over random stuffs, but works together very well when they need to, and Bailey's echolocation serves as Destiny's guide (because she's really nearsighted).
- Lilo & Stitch:
- Gantu and Reuben (Experiment 625) in the series, have several bicker spats with each other as they make snarky comments towards each other which range from their professions to their looks.
- Jumba and Pleakley have some of their moments of this as well, which includes disguising themselves as such a couple even when there's no need to and even having some spats with each other.
- The Lion King:
- Timon and Pumbaa do not show much of this in the films but its very evident in their own series as they frequently bicker with each other. Apparently, their philosophy of "Hakuna Matata" does not protect them from having such bicker spats.
- Judy Hopps and Nick Wilde. While its ambiguous as to whether their relationship is romantic or platonic, Judy acts like a nagging wife towards Nick, who in return acts like an lazy and oafish husband pretending to listen. They showed this while trying to solve the missing mammal cases.
- Bucky and Pronk Oryx-Antlerson, Judy Hopps' noisy neighbors, argued like this for at least half of their screen time (limited as it was), though their arguments are mostly childish exchanges along the line of "No, YOU shut up!". According to co-producer Jared Bush, Bucky and Pronk actually are a married couple!
- Storks: Junior and Tulip quickly get into this, though they also argue like a newly married couple when they are dealing with the baby.
- Grapevine. To Susan Crawford and Matt Brewer:
Thumper Klein: Why don't you two just get married right now? You already argue like an old married couple.
- In Harry Potter and the Prisoner of Azkaban, Snape enters the Shrieking Shack and remarks to Sirius and Lupin, "Listen to you two, quarreling like an old married couple."
- High Anxiety the Mel Brooks character and Arthur Brisbane's daughter use this to get through airport security undetected by being a loud old arguing married (Jewish) couple.
- Detective Spooner and Doctor Calvin in I, Robot.
- This is the relationship between Maleficent and Diaval, helped by the fact they've been Parental Substitutes for Aurora ever since she was a baby.
Diaval: How could you do that to me?
Maleficent: You said anything I need.
Diaval: Yeah, but not a dog! Dogs are nasty and vicious and they eat birds!
Maleficent: Fine. Next time I'll turn you into a mealy worm.
Diaval: I'll be a mealy worm, gladly!
- In The Naked Gun 33 1/3, Frank Drebin is infiltrating a family gang hired to blow up the Academy Awards. Then his wife Jane shows up, thinking that he is cheating on her. Playing his role, he suggests they keep her as a hostage. Then they start arguing (even though they supposedly don't know each other), causing the head of the gang to get suspicious and claim that they sound like they're married.
- Scientists Dr. Newton Geiszler and Dr. Hermann Gottlieb in Pacific Rim, which may be the most popular pairing in the fandom despite a couple of canonical pairings. Though they almost never stop fighting over their approaches to the kaiju, they really do seem to care about each other.
- Lampshaded by Word of God in his commentary of Red Eye when Lisa reminds Jackson of his promise that he would call off the gunman in front of her father's house:
Lisa: You know what. My dad. Make the call. Your part of the deal.
[Jackson takes the phone and puts it on the receiver]
Jackson: I still need you.
Lisa: You promised.
Jackson: And I'll keep that promise...
- This is how Robert Downey, Jr. described the relationship between his character and Watson in Sherlock Holmes (2009).
- The Force Awakens: Han and Leia. Of course, they are married, but when they reunite after having not seen each other in years, they slip back into this mode in seconds.
Han: I was just trying to be helpful!
Leia: When has that ever helped?
Han: [opens his mouth]
Leia: And don't say the Death Star.
- In Boundary the two linguists are described as this by several characters. They end up getting a Relationship Upgrade at the end making then the Gamma Couple.
- In one of the Bunnicula books, "Return to Howliday Inn", the ghost (actually Hamlet the dog pulling some ventriloquism) comments that Harold and Chester argue like an old married couple.
- Monk and Ham in the Doc Savage novels.
- It's more subtle than usual, but in Harry Potter and the Order of the Phoenix, Ron and Hermione's bickering strongly reminds Harry of Molly and Arthur Weasley's bickering at one point. Molly and Arthur are an old married couple. Pretty damn cool method of Foreshadowing.
- Shasta and Aravis in The Horse and His Boy. They end up getting married "so as to go on doing it more conveniently."
- British statesman Lord Chesterfield in Letters to His Son: "the Duke of Newcastle and Mr. Pitt jog on like man and wife; that is, seldom agreeing, often quarreling; but by mutual interest, upon the whole, not parting." (letter 221)
- Tonker and Lofty in Monstrous Regiment. Jackrum blurts out 'What are you, married?' at them in the middle of the book, though it's quite likely that he already knew they were an item.
- The bickering between Nero Wolfe and Archie Goodwin can take on this edge since their working relationship specifically revolves around the latter being hired to nag, provoke and irritate the former into working when he is determined not to.
- Toward the beginning of Redwall, as Matthias and Cornflower take care of the Churchmouse twins, Colin Vole comments knowingly that they're like an old wedded couple. He's instantly told off, since Matthias is in line to become a brother in the Redwall order, but sure enough, they're married by the end of the book.
- The Trials of Apollo: Nico di Angelo and Will Solace have been together for six months, and argue like they've been married for five decades. It's both hilarious and adorable.
- Someone Else's War: Asher and Eliza. Respectively sixteen and fourteen.
- A Yellow Raft In Blue Water by Michael Dorris: The relationship of Christine Taylor and her brother Lee's high school friend Dayton Nickles when she comes back to the Indian reservation when she contracts a terminal illness.
- The Dresden Files: The entirety of Harry Dresden and Karrin Murphy's professional relationship and friendship is rooted in this trope. Jim Butcher once mentioned to a fan that he even thought their eventual hookup was due to this trope, as Harry loved annoying Murphy even in the very first book long before either of them realized they had feelings for each other.
- Film critic Mark Kermode and radio presenter Simon Mayo are often compared to an old married couple - by others as well as themselves.
Simon Mayo: (reading a listener's complaint about her husband not listening to her opinion on films anymore) "This is for the sake of marital harmony."
Mark Kermode: What, ours?
- During a discussion of gay marriage on The News Quiz, Alan Coren claimed to be in "a form of marriage" with his regular News Quiz and Call My Bluff sparring partner Sandi Toksvig (it may or may not be relevent that Sandi is in fact a lesbian).
Alan: The exact form this takes is not easily defined...
Sandi: Now, I've explained this; it'll be like any other marriage. We won't have sex, we'll just sit in bed and eat burgers.
Alan: We did that last week.
Sandi: That's true, actually...
- In the final scene of The Moon Is Blue, when Patty suddenly starts arguing with Don about spending so much money on gambling, he tells her: "Will you kindly shut up? We're not married yet." She smiles, realizing what he's just said.
- This dynamic occurs fairly often in the Ace Attorney series.
Phoenix: (after Edgeworth withholds some info) Why didn't you just say so in the first place?Edgeworth: You're the one who screamed "HOLD IT!" and cut me off!
- Lampshaded in Phoenix Wright: Ace Attorney – Dual Destinies, because Edgeworth and Phoenix have finally hit that stage. Bobby Fullbright even points out that they're a good illustration of the phrase "close enough to argue". In their brief appearance in court together, they don't so much argue over facts as quibble about interrupting each other:
- In Phoenix Wright: Ace Attorney – Spirit of Justice, they do a little investigating-slash-sightseeing together in the Kingdom of Khura'in. Despite the country being on the verge of a revolution and the atmosphere being incredibly tense, they spend most of their time together amicably bickering. Awww...
- Apollo and Athena's dynamic is noted to be like this in Spirit of Justice. A magician in the second case mistakenly assumes they're a comedy duo practicing their "old married couple" routine when they were actually just conversing and interacting like they normally do. Apollo and Athena are both shocked that this is how they appear to others.
- Parodied, along with Ho Yay, in the Homestar Runner episode "Date Nite". Bubs goes on a date with Marzipan, and Heterosexual Life-Partner Coach Z — with curlers in his hair and a rolling pin in his hand — gets angry.
- In The Most Popular Girls in School, Shay and Mackenzie argue like this (according to Youtube comments). It really doesn't help that they were Childhood Friends.
Mackenzie: This [football] team in a juggernaut Jenna (Darabond). So like it or not, they're going to state. And when they win state, everyone's gonna want to hang out with them. And who will they be standing next to? The brand new, better than ever Overland Park Cheer Squad.
Shay: Yeah, because when they win, everybody's going to think they're cool, so we'll be cool too!
Mackenzie: Shay, that's literally what I just said.
Shay: No—no, I-I know, I was-I was just saying.
Mackenzie: OK, well, you're not really adding anything to the discussion.
Shay: I'm sorry, you didn't leave much room.
Mackenzie: OK, that's because I got this.
Shay: Well, as the Head Cheerleader, I feel like I should have the final word.
Mackenzie: You know what Shay, you're really letting the Head Cheerleader thing go to your head. I'm clearly better at bitching people out so just let me handle it, okay?
Shay: I'm sorry Mackenzie, just because you're the loudest doesn't mean that you're the best at bitching someone out.
Mackenzie: OH, YOU WANNA HEAR LOUD, SHAY?!
Shay: Oh here we go, here we go!
- Red vs. Blue: The Blood Gulch Chronicles
Tucker: I'm still picking up the reds' transmissions from when we broadcast that Lopez song. There's a lot of chatter.
Church: Well, are you at least getting any useful information?
Tucker: Nah, it's just the same two guys bickering like an old married couple. I've only been listening for like five minutes and I can already tell they're really in love. Why can't they see it?
- Exhibit uh... 307:
Grif: Hey, what are you doing?
Simmons: What does it look like? I'm getting in the jeep.
Grif: What are we, on a date? Get in the back.
Simmons: Oh, you're so insecure.
- Exhibit uh... 307:
- Kitten and the Emperor in If the Emperor Had a Text-to-Speech Device. Magnus lampshades it in episode 16:
Kitten: [wondering whether the Emperor would tell him the history of the universe] I'm much unsure if he'd actually want to tell me. I mean, if he never told you, why would he tell me?
Magnus: Well, he DOES seem to like you despite being grumpiness incarnate. He relies on you to listen to his boundless complaints and to inform him about, to quote, "stupid shit". I'd even say he trusts you. He certainly trust you more than he trusts me or any of his other sons for that matter. Actually, are you sure you're not his wife or something?
Kitten: No, of course not, but... Really? You think so??
Magnus: Indeed, stepmother.
Kitten: First of all, quiet you!
- Dumbing of Age:
- Practically every character who is sarcastic or has a bad temperament in Homestuck (Read: EVERYONE) is prone to this, most notably Karkat with Terezi, Rose with Dave, and Dirk with Roxy. Other noteworthy examples include the endless bickering of Spades Slick and Diamonds Droog, and John and Jade later on in the story.
- The Reaper and Bryony in this Catena strip. Literal Wordof God.
- Girl Genius had it Played for Laughs with Moloch commenting on Violetta and Tarvek here. With Ironic Echo when Tarvek reflects it on Violetta and Moloch himself (she had some interest in him, though it's not clear how much reciprocated) later.
- The Inexplicable Adventures of Bob!, Bob says this to the Pirates of Ipecac. And it turns out he's right!
- In Plume, this is what "cooperation" between Corrick and Dom looks like, with Dom being the carefree one and Corrick trying to play the part of a responsible adult.
- This is how Mary describes Billie and Danny arguing in Roomies! (yes, same Billie as DoA, or at least an AU version). Neither of them are amused.
- Tagii in Schlock Mercenary while joking about "her" self and the captain after he was inconvenienced by his father's wishes to get him married. Of course, Tagii is an AI... but they both know it's possible — Tagon personally knows two AI who got Wetware Body, one of which indeed married a human — so his stunned reaction was not groundless.
- Anak Zahard's parents in Tower of God. Sure, her mother mourns the lack of luxury from her old days as Zahard's princess; sure, they fight a lot, but dammit, they are risking their lives to be together and he makes the best damn chicken pie of the whole Tower, so they make it work.
- Vampire Cheerleaders: Zoe and Suki's friends often joked about them being that way, due to their constant bickering. At one point, Lori even tells them to scissor and get it over with. But it's ultimately subverted in vol.4, when it's revealed the attraction was one-sided on Zoe's end, since Suki is straight.
- Chris Farley and David Spade, which was endearing when the friendship didn't border on childish possessiveness. They were undoubtedly best friends, but they could get into some pretty fierce fights, both verbal and physical. On the set of Tommy Boy, they would sometimes go for hours without talking to each other, talk to each other through the director, etc. And when Rob Lowe — who said that they acted like an old married couple — got thrown into the mix... Well, let's just say that Chris's reaction to their "buddies' bar night" was of epic Yanderesque proportions. David got so fed up with Chris hounding him on the subject that he threw his Diet Coke on him, to which Chris responded by throwing David into a wall and down the stairs.
David Spade: Chris was actually jealous of Rob Lowe. He admitted it later. That's probably why I'm not married now; my first experience didn't work out.
