What Did I Do Last Night?

""Most people, on waking up, accelerate through a quick panicky pre-consciousness check-up: who am I, where am I, who is he/she, good god, why I am cuddling a policeman's helmet, what happened last night"?"

- Witches Abroad

Man, I reek of booze, and I can't remember a thing. Where am I? Oh God, looks like I'm on the what did I do last night page!

Might be a Noodle Incident where not even the characters know or remember what happened. Often, but not always, involves drugs or alcohol. Strictly speaking it doesn't have to be a night. It can be any alcohol or drug-induced craziness plus memory block.

The character wakes up confused in a compromising position, and then utters in confusion: "What did I do last night?" As they learn more about what happened they repeat themselves, only this time in horror: "What did I DO last night?!" Often the episode become a quest to learn the truth. Usually in comedy it's a it's Not What It Looks Like situation, but in drama it often is what it looks like, resulting in a Wham! Episode and an Aesop about not drinking.

Getting a tattoo or joining the Armed Forces is a common outcome, as is the ever-popular Bedmate Reveal. If they're in Las Vegas, an Accidental Marriage is likely.

This is a common romance comedy trope, sometimes used as a Ship Tease. For example, have two people end up in bed whom the fandom have been pairing up (despite their hating each other in canon). Have them freak at the thought that they might have had sex. Maybe have them sort of try out a "relationship" only for it to be "The Masochism Tango", but by the end of the day they figure out that no sex occurred, happily resulting in a Snap Back.

Another version can occur where everybody else does know what happened last night, but decide to conceal it so as to have some fun with the poor guy who can't remember. If the audience gets to see the poor drunk's patchy memories of the evening, they may be portrayed via Binge Montage.

You Wake Up in a Room is a darker, less comedic variation.

In Fan Fiction this is the mandatory lead-in to a Vegas Crossover.

Can also be related to Missing Time, although this doesn't usually involve alcohol. It can be Truth in Television, although the amount of alcohol you must consume to lead to Real Life memory loss is pretty close to how much you need to die from alcohol poisoning.

What are these Advertisements?

 * Jake has these experiences in the AXE shower gel commercials.
 * In a Norwegian commercial, a woman wakes up in a bed in a huge hotelroom with wedding-stuff thrown all around. Her confusion becomes complete when George Clooney enters the room. Turns out she married THE George Clooney while she was drunk.

Why is Anime & Manga here?
"Kawahama: Making your enemy more confused than yourself is the best way to overcome panic."
 * In Gintama, Gintoki ends up assisting a ninja, almost married and the target of a stalker (all the same person, Sacchan, as seen above) due to one of these.
 * Later on: Otose, Tae, Kyuubei, Sacchan, Tsukuyo, and Madao..
 * Maison Ikkoku: Godai gets drunk, . In the morning he wakes and tries to figure out what happened. His roommates are a bunch of Jerkasses so when he asks what happened they tell him two different versions:His Love Interest hates him because was teasing her and didn't put out, and his Love Interest hates him because he stripped and danced nude for her. The third roommate tries to give him a third version (also suitably horrific), but at this point he is so horrified that he runs away screaming. Trying to piece everything together with some other clues he concludes that he has to go and apologize to his Love Interest. Of course she interprets this as Godai retracting his confession of love.
 * Another version of this takes place in the Wham! Episode when Mitaka gets drunk (with Godai when their plan for fisticuffs doesn't pan out) wakes up and finds breakfast already made for him. This allowed the use of both the comedic version and the dramatic version at the same time, while providing an Anvilicious Aesop on not drinking, that is nonetheless perfectly acceptable because of the Rule of Funny.
 * Manga example: the titular protagonist of Psychometer Eiji has the ability to read psychic imprints left on objects by their owners, generally images of significant events from the owners' recent past. He also likes to party hard. This combination is put to use in several Filler chapters as a break from the rather dark main plot.
 * While Minamo Kurosawa doesn't wake up in so much of a compromising situation as in the throes of a headache, she has no idea what she did, even (especially?) when Chiyo asks what means, and Sakaki can't look her in the face, and the other girls thank her for her education, and when she asks where Chiyo heard about things like that, Yukari tells her that she herself was the source. (She had just talked about how "pervy" relationships can get.)
 * The OVA for Full Metal Panic!: The Second Raid is essentially about this happening to Tessa (thanks to Melissa Mao), and her struggles to figure out (without tipping off people who don't know about it) how she ended up waking up half naked in her commander's chair. Very Moe.
 * In volume 2 of Moyashimon, Hasegawa ends up getting drunk in Misato's room and passing out. Sawaki, Misato and Kawahama avoid the backlash by making things look even worse: Misato puts a pot on his head with his face painted on, and Kawahama and Sawaki strip naked, with Sawaki hanging from the ceiling upside-down with "Baka" painted on his back. Hasegawa leaves without incident, not wanting to remember what she was doing last night.


 * Also happens with Oikawa and Muto sampling some of Itsuki-sensei's aphrodisiac chocolates, getting roaring drunk, and Oikawa waking up naked next to Muto.
 * In the manga Sekaiichi Hatsukoi,  Yes, Ritsu has a lot of blank spots in his memory... and Masamune was probably justified when he called him a bastard for not remembering.
 * The Nordics have a meeting in Hetalia Bloodbath 2010 to figure out what happened to them after they got knocked out by the shadowed figure.
 * This was Netherlands' reaction when he wakes up on the ground to find his clothes torn and a similarly disheveled Spain sleeping on top of him.
 * In Koimoku editor-in-chief Juumonji has a moment like this after waking up only with her bra on on top of a pile composed of 1 man and 3 women (all of them dead drunk) without any specific memory about what happened after they started drinking last night.

How did Comic Books end up here?
""God... What have I done? Also, why did I do whatever it was I've done? Also, where am I?""
 * In the European Vacation storyline in Gen 13, Sarah Rainmaker and a shirtless Bobby "Burnout" Lynch wake up in bed together after getting drunk and realize that they "did". Made more awkward by the fact that Rainmaker is a lesbian and Bobby is still massively crushing on her.
 * The Sin City story "Just Another Saturday Night" has Marv coming to his senses with dead bodies and a wrecked cop car nearby. The rest of the story consists of him trying to piece together how he got there. As he says, "When you've got a condition, it's bad to forget your medicine."
 * When Tony fell off the wagon, he kept on having alcoholic blackouts. He had once even stole a medival suit of armor and forgot about it just a little bit later while in jail.
 * Yankee from the German comic Lula und Yankee apparently painted all over his girlfriend's backside. And his buddy's face. Good thing it was not a real tattoo.
 * Buffy the Vampire Slayer Season 9 #1 opens with Buffy waking up in a trashed room thinking:


 * Turns out she ends up preggers. Apparently the Slayer had so much to drink and partied so much she can't remember who knocked her up.
 * Knights of the Dinner Table: This is the end result of drinking Mojo Dave's mojo juice.
 * In an issue of New Warriors, Namorita gets plastered and has sex with (she thinks) a random guy from a bar. It turns out that he's a super-villain and uses the opportunity to steal all the team's secrets, leading to the death of one of their grandmothers.
 * Transmetropolitan has Spider and Yelena wake up in bed together after spending a night so wasted that they can't remember what happened (and considering how many substances Spider is on at any given time, that is saying something). Yelena insists that they absolutely didn't do it, but unfortunately for her Spider's glasses automatically take pictures in any situation where it seems like he is being "attacked", and these confirm they the two did the deed.

Why is Fan Works here? And where are my pants?

 * In the Stargate/X-COM crossover XSGCOM, the Commander of X-COM wakes up after his bachelor party on another planet, with no recollection of how he got there.
 * In Of Love and Bunnies, this happens twice: once when the Rangers drink Aquitian water, and the other after the Ranger Kegger. Tommy really can't remember the second.
 * In the Street Sharks fanfiction Street Sharks Redux, the protagonists wake up in a sewage pipe with no memories of how they got there or where their father is. After they mutate into sharks, it slowly comes back to them that their father's evil assistant kidnaped and mutated them.

Huh, I don't remember Film being here.

 * Dude, Where's My Car? starts out with this, and the rest of the plot is about what happened to the stoners and their aforementioned car. We never really find out what happened that night. Except that.
 * Also the plot of The Hangover, and we do find out what happened that night. The sequel is basically the same thing.
 * A classic Hollywood example in The Philadelphia Story, after Tracy & Mike's drunken evening ending with a late night swim (with a bit of Did They or Didn't They? thrown in).
 * Memento is a full-length version of this trope, although with a different mechanism than many of the above.
 * Up in the Air: Natalie has a moment of it.
 * Happens a couple of times in City Lights, where an important plot point is that the Millionaire is a party animal, and the Tramp's best friend, while drunk, but doesn't remember anything or recognize his friend while sober. After one wild party, the camera cuts to the Tramp and the Millionaire asleep in the Millionaire's bed. After the Tramp gets up to get a glass of water, the Millionaire awakens and begins looking around in confusion... and then the Tramp calmly climbs back into bed with him.
 * Played moderately well in the early Keanu Reeves vehicle The Night Before.
 * Hannibal shows a good reason not to be drinking buddies with a psychopath: "Here, why don't you cut off your face?". Said drinking buddy notes: "It seemed like a good idea at the time." (The amyl nitrate and other fun chemicals also being consumed probably made this seem better.)
 * In Sixteen Candles, the nerd wake up in a girl's pink convertible and has to ask her if they had sex last night or not. She's fairly sure they did, but neither can remember the specifics.
 * In Father Goose Miss Freneau thinks she's been bitten by a poisonous snake (she wasn't), and Mr. Eckland gives her whiskey to ease the pain. She wakes up the next morning not remembering anything.
 * In The Pink Panther Sir Charles lures Princess Dallah to his room and she gets drunk on champagne. She passes out and he puts her into his bed. She wakes up the next morning not remembering anything.
 * In the film version of Valley of the Dolls, Neely O'Hara gets high on the titular dolls and wakes up in a sleazy room with a strange man looking through her purse. She's lying in bed, and it's heavily implied they slept together.
 * Twenty Eight Days starts out with two characters coming home completely trashed and accidentally setting a bra on fire. When they wake up in the morning neither of them remembers why the bra is charred, or much else.

What is Literature doing here?
""Most people, on waking up, accelerate through a quick panicky pre-consciousness check-up: who am I, where am I, who is he/she, good god, why am I cuddling a policeman's helmet, what happened last night?"
 * According to The Salmon Of Doubt, a posthumous collection of some of his miscellaneous writings, this happened to Douglas Adams fairly often.
 * He came up with the idea of The Hitchhiker's Guide to the Galaxy after waking up in a field, looking at the stars.
 * The science fiction novel Golem100 by Alfred Bester has a place where two characters take drugs. The next ten pages or so are freaky concept art with no pictures. Then the text restores, and a policeman explains to them just what they were doing that time (each art piece represents about an hour of debauchery, such as streaking an entire city block).
 * Doctor Who New Adventures: Jason and Bernice are trapped together for an extended period of time, get drunk, accidentally trigger each other's childhood traumas, get really drunk... and nine hours later Benny's rather dazed POV is pointing out that usually, when one wakes up plus one drinking partner and minus chunks of one's memory, the most that happened is a little half-hearted groping before both parties passed out, before going on to mention that this time around, "half-hearted" feels somewhat less likely than "ferocious, violent, convulsive, and multiple."
 * This is the main theme of Henry Kuttner's Galloway Gallegher stories.(Colected in Robots Have No Tails). The main character Galloway Gallegher is explained to be a super Spark inventor, but his spark only gets sparky when he's very drunk. Thus almost every story starts with him waking and spending the rest of the story trying to figure out just how the crazy invention he made last night works.
 * One story starts with him discovering that he'd created an impossibly sophisticated robot with a huge narcissistic streak. He ultimately discovers
 * In Lonely Werewolf Girl this question is asked by Thrix after a night of Drowning Our Romantic Sorrows. The answer is, her sister's boyfriend.
 * Discworld
 * Rincewind experiences this in The Science of Discworld II after the wizards spend the night drinking with William Shakespeare.
 * A lovely paragraph from Witches Abroad:


 * In the Ellery Queen novel Ten Days Wonder, Howard Van Horn suffers blackouts. He will wake up days or weeks later with no idea where he is or what he has done in the meantime.
 * From the 13th century Saga of the Jomsvikings: After having gone utterly wasted at a banquet at the King's of Denmark, Sigvaldi, chief of the eponymous Viking band, makes a solemn vow to conquer Norway. When he wakes the next day, he remembers nothing.
 * The Red Dwarf novelizations retcon Dave Lister's means of joining the Jupiter Mining Corps into this (in the show he was intentionally working to buy a farm on Fiji). For his birthday he decided to go on a pub crawl on earth with his friends, based on visiting every location on a Monopoly board. After hitting a few places and getting confused, he stepped out to buy such a board, and woke up some time later on another planet wearing women's clothing and in possession of a fake passport. In this continuity the job serves as his manner of getting back home.

Did I really list Live Action TV?
"Ross: They would not let us get married when we were that drunk! Joey: They let you get married when you’re drunk! Most people who get married in Vegas are drunk!"
 * Played serious in the "Hangover" episode of The Alfred Hitchcock Hour, where a binge-drinking executive (Tony Randall) eventually finds out.
 * The seventh season opener of Degrassi the Next Generation does this to set up a particularly convoluted Twist Ending, where the two drunk people waking up in bed together didn't have sex...but a ton of much, much creepier stuff did happen.
 * Apparently this happens to the alcoholic Fun Bobby in Friends all the time. As Phoebe puts it when describing a typical Fun Bobby story, "So I wake up, and I'm in this dumpster in Connecticut..."
 * The definitive one on that show has to be when Ross and Rachel accidentally get married in Vegas, however. Full story: after Ross doodles on Rachel's face on the plane in apparently indelible ink, he atones by "bringing Vegas to [them]" and playing cards with her in the room and drinking everything in the minibar. Ross then suggests it would be funny to eat a lot of grapes, and Rachel compromises by suggesting they get married and then eat a lot of grapes. The next morning, neither of them remember a thing and have to be reminded by their friends.

"Ross: (to Rachel, who has been defending Mark for just helping her out of niceness, pointing to a horribly hungover Chandler) You see what men do? Don't tell me men are nice. This is men!"
 * Also happens to Ross when he sleeps with Chloe, the copy girl, after deciding to "take a break" in his relationship with Rachel.
 * Chandler does one of these a few times: once when he sleeps with his annoying ex-girlfriend Janice on Valentine's Day after being accidentally set up, and another time when he makes out with one of Joey's many sisters at a party. He doesn't know which one.

"Lister: On a mining ship, 3 million years into deep space, can someone explain to me where the smeg I got this traffic cone? Cat: Hey, it's not a good night unless you get a traffic cone. It's the policewoman's helmet and the suspenders I don't understand."
 * In Gilmore Girls, Lorelai's drunken rant at Lane's wedding.
 * Also, Luke and Lorelai go out for an evening and drink too much, and the next morning Lorelai is disturbed to realize that they didn't use protection when they had sex, leading to a But I Can't Be Pregnant subplot.
 * Brandy in the Noah's Arc movie wakes up after a drug-fueled night in a total state of confusion.
 * The whole premise of the Psych episode "Last Night Gus", which begins with Shawn on the floor wearing sandals that aren't his, Gus also in an awkward position, Lassie with a black eye on the couch with Woody the Coroner, Lassie's gun having fired three bullets, and Gus's car is trashed. And everybody seems to be pissed off with them and a murder victim got killed by three shots.
 * In the House episode "Hunting," Cameron does not forget, per se, but she does regret it.
 * Played rather cruelly in the fifth season finale: House wakes up after spending the night with Cuddy and finds little clues of their liaison all around the house, like her lipstick...except
 * Also played very seriously in House's Head and Wilson's Heart, the medical mystery of which revolve around House desperatly trying to remember the events which lead up to him waking up in a strip club mid-lap dance bleeding from his scalp.
 * In The Choice, House wakes up in an underage neighbor boy's bed after a night of binge drinking. While still creepy, it's not nearly as bad as it sounds--it was meant to show House was having problems with his sobriety.
 * In one episode of How I Met Your Mother, Ted woke up one night to find he'd hooked up with a woman, sprained his ankle, gotten his coat burned, had a phone number he didn't know written on his arm, and for some reason had a pineapple on his night stand. Almost everything was explained through a series of flashbacks, except the pineapple, which remained a Riddle for the Ages.
 * A later episode also uses this trope, only this time Ted wakes up with a butterfly tattoo just above his butt (referred to by everyone as a "tramp stamp").
 * Robin, getting ready to become naturalized as an American, decides to make a stop at her favorite bar, a pub for Canadian expatriates called "The Hoser Hut." Barney finds her the next day hung over and confused in a Toronto hotel.
 * It's how Lister in Red Dwarf ended up leaving Earth, according to the novel.
 * In the second-season episode "Thanks for the Memory", Lister wakes up after a drunken party with one foot in a cast and no idea how it happened. (It turns out that alcohol was not in fact the cause of his amnesia. This time.)
 * In the third-season episode "The Last Day", following another drunken party:

"Lister: "I remeber bettin' ya I could climb the disco wall using only me lips...""
 * And who could forget the climax of the end of Season 2, in the episode "Parallel Universe"? Lister and a female version of himself try to determine how they ended up in bed together:

"Veronica: You wanna know how I lost my virginity? So do I."
 * A Three's Company episode has Jack waking up after a wild party, finding Mr. Roper sharing his bed. While Jack's pretty sure this is Not What It Looks Like, Roper freaks out and invokes the trope.
 * In another episode Jack get's drunk with his old navy buddies and they give him a tattoo. He goes to the hospital for an operation to remove it while Janet tries to convince him not to go because she thinks the operations is a vasectomy.
 * A non-humorous example: The first episode of Veronica Mars has Veronica waking up from a party in bed without her underwear after being rufied at a party.

"Sheldon: Penny, Leonard. Would you be able to answer some questions I'm having about the events of last night? Penny: Sure. Sheldon: Question one: Where are my pants? Leonard: You might want to check youtube."
 * A Will and Grace two-parter had Will & Jack get badly drunk on Karen's yacht and wake up in bed together. Naked. They are both horrified.
 * In The Young Ones episode "Time" Rick wakes up and finds a girl (Jennifer Saunders) in his bed. Being a randy little devil, he naturally assumes they had sex. Hilarity Ensues, until she tells everyone she just needed a place to crash and got into Rick's bed after he fell asleep.
 * Variation in Firefly: after Saffron shows up on the ship and explains her "marriage" to Mal, he asks Jayne how much he had to drink the night before, on the theory that obviously he's missing something... Turns out Jayne doesn't know; he passed out.
 * Also used very briefly in "Jaynestown", so Kaylee can mess with Simon a little.
 * In a Mad TV skit, a man wakes up with a hangover to learn that he had been elected US president while drunk. His presidency was highly successful and popular (he's in the middle of his second term when he wakes up), he annexed three new states to the US (Cuba, Saskatchewan and Germany) and even managed get the cure for cancer discovered (by gathering the CEOs of the world's biggest companies and "infecting them with cancer").
 * He's also married to Winona Ryder.
 * Exact words used in the Mystery Science Theater 3000 sporking of the short "The Chicken of Tomorrow"... to describe the stumblings of a newly-hatched chick.
 * Made even funnier in the short "Keeping Clean and Neat," where a ten-year boy struggles to drag himself out of bed.
 * One episode of Black Books does this. Bernard is trying to figure out why some friends of his are so angry with him. Unlike some other examples, the only clue he's got is that he's incredibly hungover (nothing new for him). Turns out (spoilered'd for your sensitivity)  He falls and breaks his arm when leaving in a huff because they refused to apologize for blanking him. Their son's face is locked in a mask of horror, which Bernard brushes off as "He's a kid. Everything's new to them."
 * In Auf Wiedersehen Pet, Neville wakes up after a night on the town in Dusseldorf with a strange woman's name tatooed his arm. He spends the rest of the first series worrying about how he is going to explain this to his wife when he returns home.
 * 30 Rock has at least one instance of this, in which Liz Lemon, having gone to the dentist for some surgery, naturally undergoes anesthesia that evidently affects her... strongly (as in, put a waffle in her DVD player and thought that it was the best movie ever). When she goes back to work, she finds an entry marked "Future Husband" in her contact list. This kicks off a sort of mini-arc.
 * She also takes her recovering alcoholic former boyfriend out to dinner before his wedding. He orders salmon, and seems to be getting rather tipsy somehow. Seems the sauce contains whiskey, the alcohol of which would normally burn away while cooking. However, he unknowingly ordered the sauce on the side, and gets drunk. The next morning he complains of lower back pain, and doesn't notice that he somehow ended up with a tribal tattoo.
 * My Name Is Earl features this, when Earl wakes up one morning with a hangover and a married woman  who is six months pregnant.
 * On the Panel Show Would I Lie to You?, panellists will often attempt to justify unusual claims by saying that they were very drunk at the time.
 * Mad Men features a very serious one of these after Don Draper wins a Clio Award; the blackout lasts from Friday evening to Sunday afternoon, during which Don makes a pitch that succeeds in the worst possible way, hooks up with an adwoman who had been actively seeking him out since the ceremony, then hooks up with an entirely different woman (apparently the waitress from a nearby diner), who
 * The oldest brother, Tony Russo, of Blossom had been a recovering drug addict who had huge gaps in his memory. He even once forgot that he went to college and realized it while he was wearing the sweatshirt.
 * Two and A Half Men: Charlie. A lot. But one example in particular had him wake up the next morning finding out he tried to mail his pants back to the manufacturer because he snagged himself zipping up.
 * Burn Notice had a season 4 episode where the crew do this as a plan to beat a con man.
 * Smallville: They had a blatant rip-off of The Hangover after Clark and Lois co-joined Bachelor/Bachelorette party in season ten. It involved cursed/blessed champagne from a magic-wielding ally, a complete black-out after the first sip, a stolen money transport in the barn, the resident Straight Man turned Elvis Impressionist, a wedding-dressed Chloe in Clarks closet and one half of a signed marrige licence.
 * Happens occasionally on SVU when a victim is dosed with Rohypnol or similar. Played straight in the episode "Hammered," in which a man genuinely doesn't remember while drunk.
 * Erin in the first episode of Crownies when she wakes up at home after the office Christmas party, still dressed but missing one stocking, and having no memory of how she got there. She later discovers her bra hanging on the conference room doorknob.
 * An entire plot thread of the Warehouse 13: episode 'Love Sick' involved Pete and Myka waking up in bed together and trying to figure out what they did the previous night.
 * In Being Human (UK), a vampire's dependency on blood is treated like an alcohol addiction. As a result, there are a few scenes of when Mitchell drank the blood of lots of women in the seventies and woke up, completely disoriented, covered in blood, and surrounded by broken furniture and dead bodies.
 * A much less humorous variation occurs in an episode of CSI, which focuses on a teenage boy who died during a drug trip. His friend desperately wants to remember what happened that night to catch his killer..
 * Sheldon Cooper, the man who didn't even want to drink coffee because it is technically a drug, has one of these on The Big Bang Theory. Penny offers him alcohol to ease his nerves about giving a speech. As it happens, he's very nervous. The next morning, he rewords the title of the trope in his own Sheldon-esque way.


 * This clip from the Criminal Minds episode "Snake Eyes". Garcia wakes up one morning after having way too much wine and the only thing she remembers is having a huge fight with her boyfriend Kevin . So she was freaked out when she saw Morgan stepping out of her shower, in only a towel..

Where'd these jokes come from?

 * A guy wakes up at home with a terrible hangover. All he remembers from the night before is the address where the party was and using a large brass toilet with buttons on it. In an attempt to remember what he did the previous night, he goes to the house and knocks on the door. A woman answers. "Excuse me, but was there a big party here last night?" "Boy, was there ever!" the woman says. The guy asks "Do... you have a big brass toilet with buttons on it?" The woman leans back into the house and yells "Harry! The guy who shit in your tuba is here!"
 * A man wakes up in his bed remembering nothing of the party he went to the night before. He sits up in bed with a splitting headache and notices his robe and slippers are sitting out for him, and there two aspirin on his bedside table with a glass of water. Puzzled, he takes the aspirin and goes downstairs. He finds a pot of coffee brewing and his wife making a huge breakfast for him. "What happened?" He asks. His wife says "You came home completely drunk last night, puked on the neighbors lawn and then passed out on our yard, wetting yourself." "Well..." he says "why the nice treatment?" His wife says "Well, when I was grumbling and trying to get you out of your clothes last night, you came to long enough to say 'Get off me, woman! I'm a married man!'"

What's This Manhwa...?

 * In I'm At End of Your Sight Dong-ha gets very drunk waiting for Je-Hyung (who doesn't have a telephone) and . He wakes up wondering why his trousers had been taken off. He wondered if it was because Je-Hyung wanted to drive him out of the house naked.

Music seems to be here. Huh?

 * Buffett uses this trope again in is song: Permanent Reminder of a Temporary Feeling.

When did I list Tabletop Games?

 * Pathfinder has Cayden Cailean, a Boisterous Bruiser who was drunk off his ass when somebody bet him that he could survive the Cathedral of the Starstone. Three days later, when he sobered up, he was the god of Freedom, Bravery, and Alcoholic Beverages, with no memory of the intervening period.

That can't be... oh crap, it's Video Games!
""Liar! I was a perfect lady last night! But why does my tummy hurt so?""
 * This is basically the plot of Conker's Bad Fur Day. Conker wakes up after a night of drinking, has no idea where he is, and has to get home. Somehow.
 * An apparently rare bug can cause this for the player in Baldur's Gate II: Shadows of Amn by skipping over the "last night" romance dialogue and right into the "morning after" one.
 * GTA Radio used this as an ad for "Bounce FM".
 * If the player loses the drinking contest with Gemli in part 2 of A Dance With Rogues or drinks too much before going upstairs with Pia in the first part, she will have no memory of her experiences.
 * In Chrono Trigger, Lucca gets drunk on "soup" and then...


 * One quest in Skyrim starts innocently enough with a drinking contest with a random gentleman in a random bar...you then blackout and wake up half the map away in Markarth, being yelled at by a nun for trashing the local temple. What follows is a string of goat selling, monster proposing, and other debauchery you can't remember. It can potentially be worse if the girl who you borrowed the wedding ring from was your wife.  And on top of that,
 * Content Dummied Out from Fallout: New Vegas when the game still had Romance Sidequests involved a male (or lesbian) Courier and Rose of Sharon Cassidy going out drinking in New Vegas and waking up next morning to discover you'd gotten married while drunk. Naturally, The King oversaw it.

Whose Web Comics are these?
"Amber: We did not do this! Mike: You kidding? It was your idea. Amber: Your facts have no effect on me!"
 * In PK Comic after night of heavy drinking Jake finds out that he hooked up with Roberta, a drag queen in this strip
 * Although he seems to remember sleeping with a giant fish on the same night in this strip.
 * In College Roomies from Hell!!!, the boys later discover while they did while drunk: Most notably, they were featured in a cheap porn film.
 * Kid Radd invoked the gag by having the real reason the two guys are in the same bed be a prank by two of the girls moving one of them. Synchronised loud screams of horror follow.
 * A story arc in Misfile. After Ash and Vashiel wake up in the same bed with no memory of their alcohol-fueled night, Ash delivers the classic line quoted above. For full context: Ash is a guy in a girl's body, Vashiel is the Incorruptible Pure Pureness angel who longs for Ash unaware of the situation, and.
 * Ash has since sworn off alcohol.
 * Questionable Content, Faye does it here. Also in strip #1081.
 * Happens when Torg goes out drinking with Sam the Vampire in Sluggy Freelance.
 * Shortpacked: Robin eats a bowl of Cadbury cream eggs, blacks out, and wakes up to find out she's been elected to Congress.
 * In a rare variation where the reader gets to actually see it in action, Leslie gets the previously fired Shortpacked gang their jobs back after getting a contact sugar high from Robin licking her neck. Immediately afterwards, she comes down from it with no memory of what she just did.
 * The second time Robin eats Cadbury egg cereal, she wakes up in a cardboard box on the street, having passed a law creating a utopia, banged a guy, made a sex tape which got leaked onto the internet, and been dumped and kicked out.
 * Intentionally invoked by Mike. Amber and Ethan (who is gay, but slept with Amber years ago before he discovered this) wind up at a bar together and get drunk. What follows looks like a Bedmate Reveal showing that they slept together. The end of the strip, however, reveals that they both slept (separately) with Mike, who did it to drive a wedge between them. Also, a sensual oil massage from Faz may have been involved at some point.

"Luther: This first song has a lot of personal relevance for me, because I seriously do not remember getting this tattoo."
 * Used in VG Cats with Samus at a Christmas party.
 * The fictional band Owns Big Mecha in Sordid City Blues has the song "What The Hell Did I Do Last Night" in their repertoire.
 * Also, at the opening of one of Owns Big Mecha's shows:

"Dr. McNinja: Did I discover time travel?"
 * And then there's this Schlock Mercenary
 * He couldn't remember the past month, due to being temporarily dead.
 * Outside Interference: After deciding, while drunk, to kiss Kate at a New Year's party, Gina is relieved to find out, in the next strip, that she chickened out.
 * Steve and Mark in Khaos Komix starting here. Also Tom (Maria back then) here.
 * This page in The Adventures of Dr. McNinja:


 * One particularly geeky example was provided by Full Frontal Nerdity. The main characters went to a New Years Eve party at the "Goblin Hole" and look through their pockets to figure out what they did while under the influence of "Klingon War Nog". Frank finds a character sheet for the elf ranger from the D&D movie, Lewis finds a receipt for the Everquest sourcebooks, and Nelson (who hates anime) found Yu-Gi-Oh cards.
 * Sam, of The Space Between, has this happen to her a lot.
 * Out There establishes the use of this trope early in its run. On the first night they meet, Miriam and John end up spending the night in a hotel together after she ties one on . In another arc about a year later, Miriam and Sherry go out drinking and the next day Miriam's memory of the night is so spotty that she can't remember  . Another time, a hung-over Miriam thinks she remembers Sherry sabotaging her one-night stand, and assumes she must be remembering wrong  . Not long after, Miriam and   end up in bed together, and Miriam needs a recap the next day to find out what happened. Later, while touring with Steven's band, Miriam gets drunk at a party and and is later surprised to find   Still later, Miriam wakes up on Araceli's couch and has trouble remembering what they did the night before, but she figures it out on her own, confirming (in her own mind) that she doesn't have a drinking problem, after all.
 * Rhapsodies: Paul wakes up alone
 * After Quentyn and his friends celebrated his becoming a Questor in Tales of the Questor they woke up in a workshop with no memory of what they'd been doing, and apparently they bought a bunch of junk too.
 * Happens several times to Sandra in Ménage à 3. She even repeats the trope title here.

 * Not an uncommon occurance in SSDD, the fourth comic actually had the "traffic cone" gag.
 * Most people don't remember that this was how the protagonists of Megatokyo originally got stranded in Japan in the first place.
 * In Wizard School, Graham wakes up in a room after a drunken bender to find two schoolchildren (and a goat) in the room with him. His first questions are "What's a little girl doing in my bedroom?" and "What's the goat doing?".

I don't think I put Web Original here.
"I woke up this morning and my room has been completely trashed...and I think I'm wearing a chicken suit!"
 * This Bash quote. Oh gods.
 * A deadly serious version is used in Against Ill Chances. The narrator wakes up, is acting differently, and things are VERY weird. What happened yesterday at powers testing?
 * This disturbingly plausible Satirewire story.
 * The Crosses the Line Twice "Spooning with Spoony" series features first Nostalgia Chick and then The Nostalgia Critic waking up in bed with a Depraved Bisexual version of Spoony. Of course there the implication isn't so much that they got drunk as that they got roofied.
 * And then inverted in "Linking Up With Linkara", where Linkara is happy to find out he's had amazing wild sex with Nostalgia Chick and Marzgurl while drunk...he just wishes he could remember it. And they tell him it was an incredible once-in-a-lifetime event that could never be repeated.
 * Later, Nostalgia Chick and BFF Nella play a Hercules drinking game, and wake up surrounded by bunnies, with a third friend dressed like Spider Woman and hanging from a bar by her feet while sleeping, with a strange man in front of the couch making omlets on a hot plate, and Nella's mouth smeared with unfamiliar lipstick. This is capped with the words "based on a true story".
 * The lipstick is partly explained...
 * This thread, entitled 'I played Oblivion blacked-out drunk and here's what happened (via picture story)'. Basically a few days after a night of heavy drinking (of which he remembers little), he loads up Oblivion to find that he had played it for about four hours while drunk. In that time, he managed to, in his words:
 * Murder 131 people
 * Assault 65 people
 * Steal 198 items
 * Build up a bounty of 99575 coins
 * Build up an infamy of 140 points
 * Steal 1 horse
 * And create an enchanted sword called 'fcuk you UP!'
 * One Mr. Welch rule is "The party doesn't need to know about the time I woke up duct-taped to the back of a Drow Matron-Mother."
 * The Cheap-Arse Film Critic has one of these at the beginning of his Flesh Gordon review.


 * This happens in Freeman's Mind when he wakes up in the trash compator having completely forgot everything that had happened before, the aliens, the gunfights, everything - vaguely remembering that he had killed people in his dream... and a midget was involved...
 * This happens at the start of Chells Mind when she wakes up.
 * This is the start of the series Husbands when Cheeks and Brady wake up from a drunken night in Vegas and find out they're married (and they haven't been dated for long). They also can't find they're friend, Haley.

Western Animation? Where did that come from?
"Barney: Uh oh! Not again!"
 * Happens a lot in Family Guy during assorted cutaway gags.
 * Timmy once attended a party--and then is made to forget about it--in Fairly Oddparents. He apparently got a tattoo on his stomach of some girl he can't remember meeting. (Later revealed to be a grown woman who had a similar tattoo with his name).
 * Of course, this happened in The Simpsons, as a parody. Bart and Milhouse ask Apu for a slushy with maximum sugar. It's so much that they go on a psychedelic trip. Bart wakes up and finds that while drugged out, he... joined the Junior Campers!
 * Meanwhile Barney (who also tried the slushy) wakes up in a Greek cargo ship wearing a sailor outfit:

"#24: Oh shit... I thought we dreamt that!"
 * In "Viva Ned Flanders", Homer and Ned wake up from a Vegas bender to discover they've married cocktail waitresses.
 * After Homer gets drunk and trashes Springfield Elementary, his attempt to remember what happened the night before takes the form of a silent film with missing reels, which cuts abruptly from Homer having a beer at Moe's, to dancing around a maypole while wearing a toga.
 * "I need you to pick me up. I think I'm in Chinatown. Not our Chinatown."
 * This made up most of the plot in the season 19 Simpsons episode "Eternal Moonshine of the Simpson Mind," where Homer wakes up in the snow on the other side of town and must remember why Marge and the kids aren't home.
 * Used as a side joke in Futurama, "The Sting". "Why am I sticky and naked? Did I miss something fun?"
 * No drunkenness, but Time Keeps on Slippin does this with time skips. The cast acts normally during the skips, but afterward can't remember what happened. During once such skip, Fry inexplicably got Leela to marry him. She accuses him of tricking her somehow, and he spends much of the episode desperate to find out what he did right. In the end, it turns out he used a powerful gravity gun to spell out a message of love with actual stars, but alas they are sucked into a black hole before he can show Leela.
 * In The Venture Brothers episode "Showdown at Cremation Creek", #21 and #24 wake up hungover from the bachelor party of the previous night and to their horror find the Venture family locked in their holding cells on the one time they had specific instructions not to mess with them:

"Cheerilee: "Am I wearing a wedding veil?" Big Macintosh: "Eeyup." Cheerilee: "Are you sitting on a feather bed in a hole in the ground?" Big Macintosh: "Eeyup." Cheerilee: "Girls! Can you explain why it looks like I'm getting married at the bottom of a pit?""
 * In the My Little Pony Friendship Is Magic episode "Hearts and Hooves Day" Cheerilee has this reaction after the effects of a love potion wear off after she and the other pony affected have fallen into a hole.


 * In the SpongeBob SquarePants episode "The Algae's Always Greener", after Plankton used his life-switching machine to switch places with Mr. Krabs, he wakes up dazed in Mr. Krabs' office and says "Great Neptune above, what happened last night?"

It smells like Real Life in here... UUGHH!!!
"All to impress one of his courtesans, to boot. "Alexander took the lead, setting fire to the palace, followed by his drinking companions. Such was the end of the palace that ruled all of the East. Macadonians were ashamed that a city of such distinction had been destroyed by their king during a drunken orgy. As for Alexander, it is generally agreed that when sleep had brough him back to his sences after his drunkern bout, he regretted his actions.""
 * Texts From Last Night is full of examples of this trope.This one is particularly nice.
 * Darker and Edgier, with a Downer Ending, one French International rugby player woke up one morning in a police cell with no recollection of the previous night's events...
 * Another one with a Downer Ending, rapper Big Lurch smoked PCP with a friend one night, waking up the next morning...
 * The Persian Capital Persepolis was burned when Alexander and his men captured it. Standard pillage and burn tactic of the ancient world? No, just a drunken boast from Alexander that got out of hand.


 * A man named William Nixon (no relation) turned himself in to the police after learning he'd robbed a gas station in Carrickfergus, Northern Ireland while drunk.
 * From the Norwegian version of Big Brother: On the first morning of the first season one of the participants walked into the living room and found two of the others (opposite sex) sleeping on the couch, tightly embraced. They later denied the whole thing.
 * This.
 * The reason Ozzy Osbourne gave up drinking and drugs was that he had this happen to him regularly - the last time it happened, he woke up in prison, and when he jokingly asked what he'd done, he was stunned to hear that he'd tried to murder his wife Sharon, almost strangling her to death. A happy ending, actually, since it made him get off the drugs and it helped him change his (already abusive) relationship with Sharon into a healthy marriage.
 * John Larroquette once woke up on a plane... with no idea where it was headed. Too embarrassed to ask, he found out when they landed in his hometown of New Orleans.
 * A popular Facebook meme in 2011 was to post something on your status to the effect of "You and I wake up (in prison/in the back of a car/covered in shaving cream/or any odd circumstances). What are the first three words out of your mouth?" And then see what other people would say.

Was I Troping Under the Influence again? Oh dear God, The Stinger is here! NOOOOOO!!!!!
