In Marmaduke, after the titular dog causes a lot of mayhem in the house, his owner locks him out in the rain for the night and says that it was his fault the house was like this. His wife retorts that Marmaduke was a dog and thus doesn't know any better. After more heated words, his wife basically says "Marmaduke may have a backyard, but YOU have a sofa." Thus banishing him to the sofa for the night.
Nimashet: No, the rules don't work that way. Not about what we fight about, so much as how we fight about it. And this is the rule you need to keep in mind: either we work it out while we're still awake, or you go sleep on a couch. Roger: Why do I have to sleep on the couch? I'm the prince. For that matter, this is my room. Nimashet: You sleep on the couch because you're the guy. Those are the rules. It doesn't matter if this is your room or my room, this is my bed. And you can't use one of the other bedrooms. You have to sleep on a couch. With a blanket. Roger: (plaintively) Do I get a pillow? Nimashet: If you're good.
This trope was used straight in Small Wonder, when a discussion between Ted and Joan Lawson on each other's flaws goes out of hand and Ted ends up on the couch.

Parodied on The Red Green Show, where one of the recurring segments featured Red and another Lodge member offering men advice on what to do when their wives are mad at them so they wouldn't end up getting Exiled to the Couch.
Played with on Medium. Dad starts sleeping on the couch and the middle daughter tells her younger sister their parents are going to get divorced "because that's what happened to [her friend's] dad and then he took her to Disneyworld!" Actually, it was just an experiment to see if mom's habit of waking up from horrific psychic dreams in the wee hours of the morning was cutting into dad's sleep (it wasn't, surprisingly enough).
Daphne used this against Niles on Frasier when their lives get complicated after Maris murdered her lover.
Niles: But honey, you can't really blame me for all of this. Daphne: The hell I can't. If you hadn't had lunch with her then we wouldn't have been dragged into this mess, and you wouldn't be sleeping alone on the couch tonight. But you did, and we were, so you are.
Later on though he calls her on it, telling her she hasn't exactly been a wonderful support during what was, for him, a very difficult time.
Used on Mad Men, after Betty catches Don cheating on her.
Averted by The X-Files's Fox Mulder, who sleeps on the couch all the time, despite having no wife or significant other to exile him. It's a Fanon running gag that he doesn't have a bedroom. It was lampshaded twice by characters impersonating Mulder. In "Small Potatoes":
Eddie Van Blundht (as Mulder, in his apartment): Where the hell do I sleep?
And in "Dreamland", in which Morris Fletcher goes so far as to clear out Mulder's bedroom, buy a bed, and put mirrors on the ceiling above it.
Fletcher (after finding Mulder's bedroom full of junk): This guy hasn't been laid in ten years.
And given that nobody remembers Fletcher's purchases, it comes as quite a surprise to Scully that Mulder is no longer sleeping on his couch. In "Monday":
Scully: Mulder, when did you get a bed?
Played with in The Dick Van Dyke Show episode "Give Me Your Walls". Rob and Laura are annoyed by a painter who has been working on their living room for a long time. Rob swears that he will tell him to get out of their house soon, and if he doesn't, he himself vows to sleep on the couch. Laura walks right up to him and says that he had better get her out. (Oddly, Rob and Laura are always seen in separate beds.)
Mr. Bennett spends most of Lost in Austen having exiled himself to the library, after Mrs. Bennett allows Jane to marry Mrs. Collins. This only ends after she tells off Lady Catherine at the climax of the series.
A humorous example/inversion on One Life to Live. After bickering with her lover, a fed-up woman grabs the sheets and angrily declares that SHE will be sleeping on the couch. Subverted a year later when the same couple was genuinely estranged. She didn't kick him out, he left the bedroom despite her pleas for him to stay, and slept in the guest bedroom.
Several times in Rumpole of the Bailey. Hilda exiles Rumpole on at least one occasion, and Pyllida exiles Claude on another. On one occasion, Rumpole sees this coming and exiles himself.

In NCIS: Los Angeles, Deeks had to sleep on the couch in the NCIS Los Angeles headquarters due to his own house undergoing what is implied to be a strong pest infestation, which also resulted in him failing to pick up Kensi from the airport when she returned from Hawaii. He later has to keep company with Kensi until midnight after the infestation clearing at his house was delayed, to which she agrees, if he meets certain conditions, such as him driving and him paying, and having him do her laundry for a month (later specifying tht its outer-wear when realizing that he might go for the underwear as well.)
Callen spent some time on the same couch when he didn't feel like finding a new place. Hetty eventually makes him buy a house.

On Scrubs Carla gets mad at Turk and kicks him out of the room. An unusual example since Carla wasn't living in the apartment at the time, so she was kicking Turk out of his own room since she didn't like sleeping at home, and Turk sleeps withJD instead of on the couch.
Inverted on an episode of Everybody Loves Raymond. After an argument, Debra willingly goes to sleep on the couch - but takes all of the bedcovers with her AND turns down the thermostat in the house.

Inverted in Grim Grimoire where, instead of threatening to send her partner to the couch, Lillet threatens to send herself to the couch if her partner doesn't stay put. It's made all the more amusing for its open aversion of Hide Your Lesbians.
In Chibi Robo, Mr. Sanderson suffers this for spending so much money on the titular robot.
In Mega Man Star Force, when Luna Platz and the boys visit a ski resort in the second game, Luna forces Geo Stelar to sleep on the couch in their room after she catches him, Bud Bison and Zack Temple talking to the ski resort owner's daughter.

Referenced in Cheap Thrills when Elizabeth finds her son Jeordie's pot stash. She tries to make her husband have a talk with their son about responsible drug use (given that they themselves smoke pot, but are responsible about its usage) and threatens him with the couch if he doesn't (as he objects that it would be hypocritical); this backfires, however, as Mirza notes that the couch is really comfortable, so she threatens to take the couch herself and make him grow an Afro instead. However, how serious any of these threats were is questionable, as the couple enjoys having silly not-really-fights. In the end, Mirza does speak to his son about using pot responsibly, but claims he is going to flush the stash. Of course, instead he and his wife end up smoking it.
Parodied in The Simpsons. Marge "offends" Homer, who declares "I refuse to sleep with someone who thinks I'm lazy! I'm going to go downstairs, get the blankets out of the closet, unfold the couch... Um, good night" and hops right into bed.
Played straight in another episode where Marge attempts to name everything women have invented, only for Homer to point out that men have invented more things, and more important things. This leads to the page quote.
Taken a step further later in the episode, where Homer is sent to the couch again, and tries to take solace in the fact that at least he'll always outrank the dog. Smash Cut to Homer, now in the doghouse (literally), and wondering how he ended up there.
Averted in another, where Homer is disappointed in his own actions, and ascends the stairs quietly, saying "I'll understand if you want to sleep on the couch tonight." It's unknown if she did.

A variation occurred in the episode of The Proud Family regarding BB and CC's baptism. After both Trudy and Oscar's respective families left due to disagreements, Trudy exiles him to the tent (the family was forced to sleep in a tent due to Oscar inviting his family over so he'd have backup against Trudy's family, and thus occupying all the bedrooms and possibly all of the sleeping areas, period). It gets worse in that, when Trudy sarcastically hopes that there is no rain that night, it was raining, and Oscar also ends up being a victim to a skunk attack.
Yakko:Tom Jefferson stayed up to write a declaration late at night, so he and his wife had a great big fight and she made him sleep on the couch all night
In Orthodox Judaism, it is not kosher for a man to touch a menstruating woman — even his wife — until her period is over and she's been ritually cleansed by bathing in a mikveh. Naturally, this means one or the other can't sleep in the bed. Which one departs is supposed to be up to the couple, but think about which is easier: spending a few nights on the couch, or trying to make a woman on the rag do so?
Most contemporary Orthodox Jewish couples simply use twin beds which they can push together when it's permissible to be intimate and pull apart when it isn't.
The author of Hello Kitty Hell claims repeatedly that every time he slags on Hello Kitty, his wife exiles him to the couch AND the Hello Kitty sleeping bag.
After the Monica Lewinsky story broke, and after Bill Clinton finally 'fessed up to his wife, Hillary moved him out of the Presidential bedroom.
Part of a failed attempt by a delusional woman to punish her honest partner in this 'Not Always Right' story. Somewhat hilariously, it backfired for her in pretty much every way it is possible to backfire (and the fact that they didn't actually live together was only the start).
Performed more successfully in this 'Not Always Romantic' story (a spinoff site of Not Always Right).
