24: Alan Wilson has an "Oh Crap" look about him at the conclusion of Season Seven when he realises he is about to be tortured by Renee Walker.
77 Sunset Strip: On the episode “Secret Island”, Stu Bailey and some other survivors of a plane crash arrive on a small tropical island. Finding a tower, he climbs to the top to survey the surroundings. The first thing he sees is a giant bulls-eye painted on the beach. (This was before the nuclear test-ban treaty.) They later find a boat that looks sea-worthy enough to get them to safety, but when they shove it in the water, all they can do is watch as it quickly fills with water and sinks.
Jimmy: Well, because, that first stick of dynamite he showed us said on it it was made by the Apex powder company, but when I looked for the Apex powder company in the phone book, it wasn't even listed.
Superman: But the first stick did explode, remember?
Lois: And the fact that a company isn't in the Metropolis phone book doesn't mean that it isn't in some other city.
He collapses into the chair.
Angel: This is a frequent reaction to Angel vamping out.
A memorably well-done example (in puppet form) in "Smile Time"; when Angel gains the upper hand fighting Polo, the leader of the puppet demons, Polo comments that Angel must have a bit of demon in him. Angel responds he's got a LOT of demon in him and turns, for the first time in the episode, into a vampire puppet. Polo's face expressed the oh crap-ness of the situation remarkably well.
A wonderfully humorous moment in "Redefinition" from season two has Drusilla, fresh off a series of her long-winded and insane ramblings, regarding a seriously ticked off Angel who had just killed all ten of the 'elite' warriors that Darla was trying to raise to cause a little havoc. Her reaction? "Shit." And then he lights them both on fire, using the cigarette dangling from his mouth and an as-yet unnoticed trail of gasoline. Darla has another Oh Crap moment when she DOES notice, too late.
Played well with Cordelia when she finds herself transported to Pylea, a hell dimension. Looking around at the primeval forest, she loudly enunciates "Oh. Crap."
One occurs after the rest of the gang arrives, when the mooks show up while Lorne is singing.
Lorne: Stop! In the name of love,/before you break my heart/think it ooh sh—
A particularly good example has Wolfram & Hart, the evil corporation that has been trying to make Angel's life Hell and profits on people's misery, being trapped by Darla and Drusilla. Angel enters in an expected Big Damn Heroes moment, only to subvert it by saying he won't save them. The look on Holland Manners' face is brilliant. He pleads "People are going to die!", only for Angel to echo his earlier comments: "And yet, somehow, I just can't seem to care." It's the first major sign of Angel's descent, but it's hard not to cheer for the Laser-Guided Karma the lawyers received.
More or less everything about Illyria is a cascading series of these, from when she first manifests to when Cyvus Vail realizes that the petite young woman he was taunting is taking on a blue hue as she's swinging a fist at his skull.
Ashes to Ashes: In 2×01, DC Chris Skelton has a literal Oh Crap moment when he alerts the team that the sewer they're investigating is not tunnel 96, but 69 (See image above). In a DVD commentary of the episode, the shows creators point out that this particular scene was designed to have absolutely nothing to do with the rest of the episodes story or the overall arc.
El Barco: In this upcoming Spanish TV Series, on the bridge of the titular ship, the captain comments on the noise the RADAR screen is making, saying that each dot on it represents a ship and the sounds mean those ships are emitting an SOS signal. When the RADAR device turns completely silent and no ship appears anymore on the screen, those on the bridge (and those that are seeing it) are obviously thinking "Oh, crap."
In the episode "Six of One", Cavil experiences this when newfound rebel leader Natalie reveals she's given some Centurions free will — and they're not pleased about what Cavil is doing.
Cavil: Say WHAT!?
After seeing The Mutiny spiral out of hand, with corridor to corridor fighting for its entirety, Gaeta and Zarek both experience this moment, one behind the other, when the jump drive is broken. Gaeta in particular practically goes into a fugue state for a few seconds while Zarek gets very worried and angry until both become resigned to the fact they have lost.
Becker: In the second to last episode, the scene at 8 minutes we see Becker's biggest 'Oh Crap' as he listens to a Tear Jerker .
When Booth gets the phone call in Aliens in a Spaceship that Bones and Hodgins have been abducted by the Grave Digger.
The episode where the Grave Digger gets shot, the shooter spices the evidence with taunts aimed at Booth, up to and including buying land in his name. When Booth goes to confront him there, the shooter laughs "You can't come onto my property without a warrant." Booth says "I don't need a warrant. (crosses the property line) This property is owned by Seeley Booth." The gunman turns and runs.
When Hodgins blows Angela's secret that she thought she was pregnant to Wendell.
At least twice in the fifth season — once when a building collapses on her, and right after being teleported high into the sky by Willow — Glory realizes what's about to happen to her and manages to get out "Oh, sh..." before the camera cuts away from her.
In the episode "Innocence", Drusilla and Angelus are standing in a mall near the recently resurrected Judge, a demon who "Cannot be killed by a weapon forged". Buffy shoots him with a crossbow, which catches the Judge's attention. He delivers the "Cannot be killed" line (again), and Buffy pulls out a rocket launcher. "Oh Crap!" covers Angelus and Drusilla's faces, and they run for cover. The Judge, however, looks at the launcher curiously, and asks "What does that do?" Buffy demonstrates: *BOOM*
In "Checkpoint", at the very end of the episode, after Buffy's speech of awesome against the Watcher's Council, she demands to know what Glory is.
Buffy: Just tell me. What kind of demon am I fighting?
Travers:(brief pause) Well, that's the thing. She's not a demon... She's a god.
Buffy:(eyes widening, lips quivering) Oh. (cut to credits)
Faith has one in "Enemies" when she realizes how thoroughly Buffy and Angel have played her.
Warren when he learns that Buffy survived being shot.
In "The I In Team" (S4x13), when Professor Walsh realizes how thoroughly screwed she is when Buffy reveals that she's survived the little assassination attempt. Not to mention the fact that Riley, her best agent and Buffy's boyfriend, also sees it after she blatantly lied to him.
Andrew gets one in the season seven episode "Never Leave Me" when he runs into Willow in the butcher shop. His subsequent reaction indicates that she's probably had a recurring role in his nightmares.
In the first Spike comic of the Season 9 comics, Spike is knocked out and up by a group of demons who want to steal his spaceship. Said demons walk onto the ship, asking the last three remaining cockroach aliens(who have become Spike's lackeys),
"Okay, which one of you cockroaches is in charge of this heap?"
The other two aliens point at the one in the middle, who also happens to have a broken leg, who gets an Oh Crap look and just reponds with
Again the Season 9 comic in Angel & Faith:
Faith: "Oh Crap. Hey, little, when you said we'd have to fight 'Quor'toth itself,' what did you mean?"
Demon: "The Old One who gives this world it's name. Why?"
Yet again in Season 9 when Nadira and some other slayers show up Giles' house. And they know Angel is there.
Mayor Wilkins has one in "Gingerbread". Blink and you'll miss Wilkins suddenly start looking rather uncomfortable when Joyce discusses the horrors that happen in Sunnydale.
The First Evil has one when Buffy, who it was just taunting, gets up from a supposedly mortal wound during the Final Battle.
Simone has one when Buffy shoots the lock on the Ragna Demon's cage, and locks her and her gang in a room with it.
Burn Notice: Likes to sprinkle these throughout an episode, usually when the Villain of the Week realizes they've just been played, and/or see something explode.
"Oh Crap" is the exact line spoken by three Monster of the Week demons when they find themselves suddenly minaturized, trapped in a dollhouse, and about to be blown up by the Charmed Ones. Seconds earlier they had planned to do the same to the Charmed Ones.
Piper has a moment in "The Courtship of Wyatt's Father" that is an example of a mental "oh crap" when she finds out that she's pregnant with Chris.
Piper: No, I'm not [pregnant], I mean how could that happen, I mean, I know how that could happen, but, it... (Oh Crap look of realization) What am I gonna do?
Piper once caused the entire underworld to have an Oh Crap moment the first time they threatened Wyatt after he was born. They started taking out any threats to him themselves just so she wouldn't go on another rampage.
The villans on Choudenshi Bioman had this when they realized their plan to assassinate their leader failed and he was ready for it
Chuck: Happens a fair amount, mostly to the Bad Guy du Jour when they realize they're beaten. When Chuck solved the slide puzzle on top of the box thought to contain a deadly chemical weapon which actually contained a knock-off Kool-Aid flavor, he and Sarah had a great Oh, Crap moment. And a similar one when Dr. Wheelwright, played by Freddy Krueger himself —- Robert Englund —- set off his fear toxin on himself and Chuck. And a big one when Chuck realized that Shaw really was working for the Ring. Almost too many to count, really.
This show has one in the episode "Time Bomb". Quote Brenda: "The school's not the target. We're in the target."
Tao's terrified scream of "Hooooly CRAP!" when he stopped a tank full of sarin gas rolling towards him with his foot.
The first time Brenda encounters serial rapist and killerPhilip Stroh and he walks free because there's no evidence against him, he gets into his victims' houses by having an accomplice ask to use her bathroom at some point just before and so that the accomplice can unlock the bathroom window for him. So when Brenda has encountered Stroh for the third time, thus alerting him to the fact that she's trying to nail him again, and she walks into her bathroom at home only to find the window wide open, she doesn't really have to say anything. Her face says it all.
The look on Chief Pope's face when Brenda pointed out that he had given all the evidence including a loaded gun to a Detective 'Dick Tracy'.
In season one, a smarmy young punk killed his parent's Mexican maid, and then skipped down to Mexico with tons of money to live in luxury until the police lost interest in him. Brenda went down to Mexico and asked the Mexican police to help her interview the punk, who was arrogant and insulting, until Brenda said that they didn't have enough evidence to indict him, so they would indict his mother, unless the punk admitted to the killing, preventing Brenda from going after the mother. The punk laid out the whole crime, finishing with "But you can't arrest me because you have no jurisdiction here." Brenda agreed, but then pointed out that the two Mexican police officers standing behind the punk spoke excellent English and just heard him confess to killing a Mexican citizen. Cue an epic Oh Crap moment as the punk realizes that he will spend the rest of his life as an American in a Mexican prison. He is dragged away screaming and begging to be extradited to Brenda's jurisdiction, to no avail.
In the episode "Ashes to Dust", the Monster of the Week has this expression just as he realizes that his "accomplice" didn't intend to leave the building alive and planned to kill them both in the fire.
"Compulsion": Three college students are stuck in an elevator with fire alarms going off all around them. The doors are levered partly open and their friend Clara appears. They beg her to help them, and then one of them asks if the building's on fire. Her response, terrifyingly calmly, is "Not yet", bringing this response even before she starts pouring accelerant...
This "Oh, crap" moment from "In Name and Blood" doubles as a Crowning Moment of Funny. Garcia sees Morgan's phone number on her caller ID. Unfortunately, he's not alone and he doesn't answer the phone:
Garcia: Talk dirty to me.
Strauss: This is Section Chief Erin Strauss. (Both Morgan and Garcia have "Oh, crap" expressions. JJ is amused.)
Garcia (horrified): Ma'am, I think it goes without saying that I was expecting it to be someone else.
CSI NY: Danny, when he asks Lindsay what she wants for lunch not too long after Lucy's birth. She responds with a whole list of foods, and Danny gets this kind of look. She has to reassure him she isn't pregnant again.
The Day of the Triffids: In the second episode of this 1981 BBC mini-series adaptation, the hero John witnesses a number of these reactions when he meets individuals who realize that 99% of the population has gone blind, and they start thinking through the consequences. A medical doctor eventually jumps to his death rather than deal with the aftermath. John himself has a similar expression on his face as the father of a young, working-class family walks him through the implications.
Deadliest Warrior: The simulation in the Season 1 finale had two beautiful Oh Crap moments made by the Taliban insurgent when he noticed that he was about to be a casualty of friendly fire via RPG, and the last Taliban insurgent when he realized that the IRA insrugent had trapped him in a bus with a Nail Bomb in it.
Dead Like Me: George in the first episode. "They say your entire life flashes in front of your eyes the moment before you die? That might be true if you're terminally ill, or your parachute doesn't open... but if death sneaks up on you, the only thing you have time to think is: Aw, shit!"
Sierra's rapist handler Joe Hearn in the episode "Man on the Street," when — on the verge of assassinating Mellie — he hears Adelle's voice on the answering machine: "There are three flowers in a vase. The third flower is green." It's the last thing Hearn ever hears, as the sentence triggers Mellie's fighting imprint; she kills her would-be killer within 15 seconds.
Adelle's reaction in "The Hollow Men" when Boyd plays a recording of the trigger phrase on an intercom, causing Mellie to shoot at Paul.
In the 2000 miniseries, the Fremen have a four-part opening to their assault on Arrakeen. First, they blow up the Shield Wall with a nuke. This is followed by a massive sandstorm, a squadron of ornithopters, and four sandworms carrying Fremen warriors. In between each part, we shift back to the Imperial Palace to see the Oh Crap reactions on everyone's faces.
Satisfying is the expression on Rabban's face when he sees that he is surrounded by an immense, eerily silent mob of the very people he had enjoyed brutally oppressing. The fact that he just drops his knife and lets out a cry of abject despair as the mob swarms in and guts him is icing on the cake.
The expression on the Baron's face when he realizes that a little girl had just poisoned him. Him, the Baron of Geidi Prime, brought low by a four-year-old girl. Oh Crap indeed.
In an early episode, Aeryn accidentally detonates a weaponized black hole on board Moya. Crichton, who was trying to stop her, just has enough time to whimper "Oh God!" before Moya implodes. Thankfully, it's not permanent.
Crichton, upon seeing Rygel's homemade bomb rolling towards him.
Durka, upon seeing Crichton's homemade bomb rolling towards him.
Mal himself, at Serenity Valley when he realizes that they have lost the war. It goes on and on and qualifies as troubled Thousand-Yard Stare.
The episode "War Stories": The look on Niska's face when Mal shows just how much of a tough bastard he is by getting up while the guard's back is turned and sticking him with the same nasty torture device that had briefly killed him, and then proceeding to show Niska "the real me now".
Jayne's face when River offhandedly reminds him of this: "I can kill you with my brain."
The legendary line from Psycho for Hire Jubal Early, and that priceless look on his face:
"You're not in my gorram mind! You're on my gorram ship!"
Memorably averted by Jubal Early when he is floating away in his spacesuit to probably die. He doesn't look distressed at all.
River Tam adopts this look in "Ariel" when she realizes the Hands of Blue are coming.
Frasier: Niles Crane gives off an Oh Crap expression when, while driving home from work, is hearing Frasier having sex with Kate on the radio (due to Kate accidentally switching on the the microphone).
The season 2 finale has a doozy at the end. Two words: THREE Blasts.
Edd:Three blasts... RUN!!!!
In the Battle of Blackwater, Tyrion Lannister expresses a quietly dismayed, "Oh fuck me" when his storming party destroys Stannis battering ram, only for the rest of his army to come charging along the riverbank towards him.
In Season Three "And Now His Watch Is Ended" the slaver Kraznys has been hurling insults at Daenerys in Valyrian, since she's been using an interpreter all the time while she's been in Astapor. Then moments after she finishes the purchase of all the Unsullied slave warriors in Astapor, she reveals that she speaks Valyrian, and has always understood everything he said. Oh, and she just ordered said slave army to slaughter the slavers.
In "The Rains of Castamere" (3x9): Catelyn hears the titular song, and watches as the doors are locked shut. Made all the worse by the fact that for a few moments between this and the actual massacre, everyone else remains merrily oblivious and she's apparently the only one to know that something very, very wrong is about to happen.
Glee: The whole club has an Oh Crap moment during the first season's Sectionals competition. When they first arrive at the competition, they're told that they will be performing last, which they are pretty happy about... until the competition actually starts and they gradually come to realize that their entire set list has been stolen by the two teams performing before them. The looks on their faces as they watch all their songs being performed by the other teams are ones of absolute despair.
Mohinder disables Ax-Crazy villain Sylar's superpowers in order to torture, taunt, and eventually kill him. But when he pulls the trigger, the bullet stops in mid-air, and Sylar unstraps himself from the chair and stands up, having mysteriously gotten his powers back. Mohinder freezes in place, and the look on his face when he realizes he's now at the mercy of an incredibly powerful Ax-Crazy serial killer he's just spent the last hour torturing, belongs in the Oh Crap hall of fame.
Sylar gets one of these too on Kirby Plaza after getting several super-powered punches to the face looks up just in time to see Hiro teleport in ready to stab him.
In Volume 3, The look on Bennet's face after he realizes that Peter is no longer possessing Jesse.
In the end of Volume 4, Sylar makes it clear he's no longer interested in humoring Big Bad Danko's orders. Danko casually stabs him in his weak spot, seemingly killing him. When Danko turns to walk away, Sylar rises up from the ground and looms over Danko, clearly very, very much annoyed. The look on Danko's face is priceless.
In the finale, when it looks like Sylar's plan to get close to the President so that he can shapeshift into him is about to succeed, we find out that he can't because it's actually Peter, who stole his ability earlier and in turn stabs Sylar with a tranquilizer. The look on Sylar's face shows that he's finally been owned after 3 seasons of fighting him with no clear winner, followed by a Badass quote from Peter:
"You didn't think I took that one from you, did you?"
Sylar gets an Oh Crap, when he realizes that Peter took the Haitians power, meaning that hes going to have a fist fight with the guy who wants to kill him the most.
After Sylar is brainwashed and shapeshifted into a copy of Nathan Petrelli, we see a scene where Nathan's mom Angela (the whole thing was her idea) meeting up with him at his office to take him to lunch. On their way out, Sylar/Nathan spots a clock ticking one second off-time and it annoys him (this was always one of Sylar's known quirks. He stops to fix the clock. In the background, Angela Petrelli watches, and as she realizes that her "perfect" creation is starting to show signs of his true self again, her expression can truly only be described as Oh Crap.
Colonel Hogan gets one when he realizes that the fake bomb he's pretending to disarm is actually a real, live bomb—and that since it's right on top of Carter's portion of the tunnel, he has to go ahead and really disarm it.
Horatio has his first midshipman command, taking a prize cargo ship to England. He's sleeping and suddenly wakes up, realizing that the ship was holed when they took her. A long shot of his very open eyes and slightly open mouth follows. Yeah, the ship is going down.
Archie has an Oh Crap expression when one Jack Simpson, his tormentor and bully from Justinian, is rescued and gets aboard their new ship Indefatigable. He volunteers himself to participate in a raid the "Indy" crew plans. Lieutenant Eccleston agrees and says Simpson will go in a boat with Archie and Horatio. Cue Archie's Oh Crap face.
Horatio had it rough in "Duchess and the Devil":
He entrusted the Duchess with super important dispatches when they were about to be captured by the Spaniards and taken to prison. He realizes he's screwed when Archie tells him that the Duchess is not a Duchess but actually an actress.
One 'I'm screwed' face comes when a French soldier recognizes her as well, and Horatio thinks he will find the dispatches.
When his sailors tried to escape without his supervision, they did not get even out of the prison. When they are caught and Hunter is shot in his leg, Horatio's desperation is palpable.
When Crazy Captain Sawyer is concussed and unconscious, Horatio takes the opportunity and has a shower on deck to freshen himself after his endless continuous watch, which he was unjustly assigned as a punishment. Everybody watches, cheers him and they have fun, but then Captain Sawyer makes an appearance, complete with ominous music. Horatio's face says it all.
Horatio realizes he has made a big mistake about five seconds after proposing to his friend Maria. She is crazy about him but he only has platonic feelings for her at best. Fortunately she doesn't see it.
At the end of the season 5 finale when House realises the hallucinations have not gone away, but gotten worse as imaginary Amber and Kutner show up to mock him, followed by what he thought was a lipstick tube in his hand being revealed as a vicodin bottle, meaning he'd gone from merely seeing people who he knew weren't there to full-blown losing track of reality, no words are said but the look is one of the strongest examples of this trope ever. He still has it as he's being driven to the rehab/asylum at the end.
In "The Itch," House uses a gigantic tank of aerosol pesticide to a single mosquito in his apartment. He turns on the spray, spots the mosquito, which he chases to his gas range. He swats at the mosquito, misses, and accidentally lights the stove. When House realizes that the flammable pesticide is still filling his apartment, he simply mutters an interested "Oh," before his apartment explodes. It turns out all right.
In "iKiss", when Carly asks about the prank Freddie pulled on Sam.
Carly: What did you do?
Sam:OPEN THE DOOR, BENSON!!!!!
Freddie: Call the police!
Everyone in "iStill Psycho", when they realize that Nora and her family plan to keep them as their prisoners forever.
Income Property: Scott MacGillivray has actually turned white on camera when opening walls to find dangerously poor construction; on one occasion he found a chunk taken out of the main support beam for the entire building and on another he found an illegal electrical system that got worse the more wall he opened. Then there was the severe mold he uncovered, leading to an evacuation.
The Invisible Man: This starts as the Hero's catchphrase, although later it is used by almost all of the characters in the same intonation. His delivery is invariably in the "This Is Gonna Suck" range.
Especially funny when subverted by the Bad Guy Arnaud, when he shows up suddenly, sees the look on Darien's face and beats him to the line. "Yes, Yes, I know...Oh Crap."
Iron Chef America: Battle Thanksgiving Leftovers, Michael Symon has an epic Oh Crap face when the Chairman reveals his "culinary curveball": liquid nitrogen.
JAG: In the Season 8 episode, Empty Quiver, Cmdr. Turner is looking for a missing nuclear warhead with the submarine's loading crew. They end up realizing that the warhead is missing because one of them hung a dropped tag back on a torpedo tube door incorrectly after a power outage, making it seem like the torpedo tube it was in was empty. It ended up getting shot out into the harbor while they were firing water slugs back at the Navy dock. The look on their faces, that they lost a 10-ton nuclear warhead, caused a major panic attack for everyone involved, and killed their Navy careers because of one small friggin' mistake, is this trope all over. On a similar note, though not shown on screen, the Navy probably had this when the warhead was declared missing to begin with.
In Kamen Rider Dragon Knight, for a brief moment as the 13 riders are pulling their Link Vent cards out, Xaviax smug exterior actually slips into a facial expression picturing that he realized how much screwed he is.
The moment when Torque unleashes his Final Vent. Even transformed, the way Wing Knight takes one look at Magnugiga powering up and stops short before he legs it just says it all.
Last Resort: A VERY serious Oh Crap moment when the launch orders are read by the Captain of the U.S.S. Colorado.
Law & Order: This happens in the various series quite often, considering how many Smug Snakes swear they can beat the rap, and are then proven incorrect. The best was the closing statement scene in the episode "Life Choice" in which a fundamentalist nutjub got served by ADA Ben Stone rather magnificently.
There's another great moment in the Season One episode, "The Troubles" where the accused is an IRA insurgent, Ian O'Connell, who's charged with killing a convict he was handcuffed to for squealing on the IRA. A third convict was also handcuffed to the victim at the time and is later murdered by another IRA member. O'Connell's defense is that while he's a proud member of the IRA, he's also an Actual Pacifist who's never committed a violent act himself. After O'Connell states this on the witness stand, Stone then calls a Surprise Witness to undermine O'Connell's credibility on this, a woman who's husband and five year old daughter were both killed by an explosion from a bomb she had witnessed O'Connell place near them. All Stone has to do is state the name of the witness, Mrs. Bridget McDiarmid, and the instant Oh Crap that appears on both O'Connell and his lawyer's face is priceless. It's clear they both already know who she is and just how screwed they now are.
Law & Order: Special Victims Unit episode, Born Psychopath, Fin Tutuola looks for Henry in the bathroom where a neighbor, Toby, lives. As he searches, Tutuola finds out that Henry had killed Toby's pet dog Snowball. One could tell the look on his face that Toby was going to through Post-Traumaic Strees since there was no way it could be cover-up, but Tutuola does tells Toby and Toby's dad not to look and gets them out.
ADA Casey Novak gets her CMOA in "Svengali", where a serial killer who thrives on his many fans has a fan who has been copying his work. He brokers a deal with Casey that if he testifies, she'll transfer him to a federal prison, which have much better accomodations than state prisons. After he testifies and his fan goes down, he's smirking at Casey, clearly thinking he's got the best of her, when she whips out this gem of a line:
Casey: You're gonna love Florence Super Max: 23-hour lockdown, no visitors, no mail, no phone calls... no human contact for the rest of your life.... How do you like my work?
Eliott Stabler tracks a child pornographer to Eastern Europe. Once the man's in custody, he smugly states that he's not afraid of an American cop, since they're not allowed to brutalize suspects. Stabler exchanges a look with his local contact, who tells the guard to leave the interrogation room. She then calmy informs him that they're not in America right now. The man has just enough time to register an Oh Crap face before a Stabler-style beatdown.
Leverage: Parker has one while rescuing a bunch of Serbian orphans and opens the door to one of the bad guys who specifically recognizes her.
In "The First David Job", Eliot has this reaction upon discovering the woman he's been hitting on all evening - fairly successfully - is his boss's ex-wife.
Life: The rapist who thinks he's badass because he's forced Reese to drink a bottle of vodka has a magnificent 'Oh Crap' moment when he realizes he's underestimated her. Just a little bit.
LOST: Although he quickly recovers, Ben Linus's initial reaction when he sees John Locke alive on the Island after Ben killed him is a definite Oh Crap moment.
There are probably about a million on LOST, since the show is just like that, but the most iconic are probably:
"He wasn't on the manifest!"
"Only the thing is, we're gonna have to take the boy."
Desmond's face at "NOT PENNYS BOAT" and Charlie drowning
"I was wrong!"
"I'm seein' in, but I'm not believin' it."
"My name is Sayid Jarrah and I am a Torturer."
Misfits: Given just how profoundly luckless the characters are, this show features quite a few of these:
The entire team suffers one of these moments upon realising that their probation worker has gone insane, hacked Gary to death with a fire axe, and is now coming after them.
Nathan, trying to activate his dormant superpowers, decides to sit in a shopping trolley at the top of a very steep embankment in an attempt to see if he can phase through solid objects at high speed. Since he's only stopping himself from rolling down the hill by holding onto a nearby railing, he's naturally a little hesistant, so he decides to turn around and check the back of the trolley for brakes- and accidentally lets go of the wall. He has just enough time to shout "Oh, SHIT!" before the trolley starts moving.
Simon has a very subdued version of this when he discovers a construction crew working on the site where the corpses of Tony and Gary were buried.
Two episodes later, Simon gets another moment when he realises that Sally the probation worker has stolen his mobile phone- the mobile phone with the evidence of Tony's death on it. Cue open-mouthed gape of horror.
In the episode "The Legend," Rudd (the Big Bad of the week) is orchestrating a plan to return Nazis to power via a dummy pretending to be Martin Bormann. Rollin, who's there pretending to be one of the wealthy men involved, finds this out - and pulls the rug from under the leader by pretending to be Martin Bormann himself. The Oh Crap expression on Rudd's face when he sees him - and knows he's fake, but can't expose him without showing he himself has been lying all along - is absolutely priceless.
Usually had more than one of these moments in each episode. The first two or three were generally phony - the viewer didn't know if Jim Phelps' convoluted plan was about to blow up or not. The last one was when the villain finally realized that he had been played like a kazoo.
The Muppets: The characters have perfected the art of the Oh Crap face from their beginnings on The Muppet Show. Kermit shows a lot of fear squashing his face up and Beaker's face was even made so he's in a perpetual look of shock.
My Mad Fat Diary: Rae has this reaction to getting stuck on the slide in the first episode, with everyone staring at her scars on her legs. Averted, as she makes light of it and simply asks Chop to help her down.
Mythbusters: Usually avoids this, since they very carefully plan out their dangerous testing to ensure that nothing goes wrong. However, there are a few particularly spectacular results that they didn't expect, leading to genuine Oh Crap expressions on the crew.
While testing the myth about driving a sedan under a semi truck, turning it into a convertible, they're wildly successful at ripping off the top of the car...which then speeds past the semi, crashes into the sand berm behind it, and flips over the berm. This provokes an a positively gleeful reaction from the build team... until they realize that they don't know what's behind the berm.
The Build Team also has this reaction on the rare occasion when they realize they're not standing quite as far away from a massive fireball as they probably should be.
From the Compact Compact re-visit, when their semis start to go out of control. You can hear the Oh Crap in Jamie's voice when he says "It's gonna go into the wah-ter!"
The looks on Jamie and Adam's faces during the "Border Slingshot" is an example of this, and also implies a brown trouser moment. The narrator goes on to say "Terror. It's hilarious!"
Another memorable one was during the "Bottle Rocket Blast-off". Memorable because Grant actually yelled "HOLY CRAP! RUN!" as the 2kg weight went way higher than expected.
NCIS: The seventh season premiere has a beautiful one.
Tony: Remember when I told you my boss was a sniper?
In one episode, where Gibbs is forced to deal with Kyle Boone, a serial killer he'd put in prison years back, in order to find where his victims are, the team learns that Boone has a protege who has been continuing his work, and has captured recurring character Agent Paula Cassidy. In the end, Boone thinks he's got one up on Gibbs after being sent back to Death Row, due to being the only one who can identify his protege and lead them to Cassidy's body. His absolutely epic Oh Crap moment hits when Cassidy reveals herself, explaining that his protege is, in Tony's words, "kinda dead."
Gibbs: Enjoy hell.
Boone: *dragged back to his death sentence kicking and screaming*
Noah's Arc: There are several throughout the series, but Eddie has a particularly epic one when Chance catches him with another guy via Car Meets House.
The Office (USA): Jim gives a phenomenal "Oh Crap" face when he realizes that Michael has tricked him into attending his dinner party. Dwight has another when he sees Michael about to eat wild mushrooms.
Even more so in the episode 'The Lover'. Michael tells him that he's sleeping with Pam's mom. Initially Jim thinks he's joking but when Michael tells him which car she drives, he goes 'Oh Shit!'.
And when Michael tells Pam that he's seeing someone, Pam asks who it is - Jim, who's stood next to Pam, immediately looks into the camera like he's frightened for his life.
"I sent it to you at firstname.lastname@example.org. Wait... packaging@dundermiffin- Uh oh."
Regina and Mr Gold plan to frame Mary Margaret However, Kathryn is found alive. When Regina confronts Mr Gold, she realizes he has made it all lead back to her. Her facial expression says it all!
In that same episode, August pretends to be Mr Gold's estranged son, Baelfire, who disappeared after being drawn int a portal. He and Rumplestiltskin were to go together, but Rumple chickened out. However, when Mr Gold figures it out confronts August and turns the tables on August. August knows he's messed up. Gold's face when August tried to control him clearly said "What an Idiot, this dagger doesn't work here!" because August is really Pinocchio he knows who Mr Gold really is and what happens to those who anger! Mr Gold tells him "The chances of you surviving this encounter are pretty slim" and tells him he has to work for him if he wants to live. August clearly looks like "I've done it now!" at the end.
Emma has a brief one in the season finale when Regina reveals that Mr. Gold is Rumplestiltskin. (Presumably, she's realizing that she promised him a favor, and has read enough of Henry's book to know how his deals usually end.)
In the second season opener, the townsfolk, now remembering who they really are and what Regina did, storm her house. She tries to drive them off with her newly restored magic, but nothing happens. She has a split second to realize what's about to happen before the mob grabs her.
Only Fools and Horses: After Granddad learns Slater is in the police, his jaw drops for about thirty seconds. A couple of minutes later in the same episode, the whole family gets one when Slater arrests them, and Slater himself has one when Del's Batman Gambit pays off.
The episode called "Tea For Three" gives Del an epic one when he realises that Rodney has set him up in front of the handgliders.
Mighty Morphin' Power Rangers also gives us a few good ones. Rita's shocked "Huh?!" after the Mega Dragonzord vaporizes Mutitus, and a few "Uh-oh"s on some occasions when she sees her monster is about to be defeated. In the third season her skeletal brother Rito Revolto also delivers a priceless "Uh-oh" when he sees the Ninja Mega Falconzord about to pound him. Then in Power Rangers Zeo Rita and Zedd both have an Oh Crap moment when they see the Machine Empire arriving, and flee in Serpentera.
Even a robot not of the humanoid type manages it once. In "Doomsday," when Rita causes Titanus to begin sinking into the earth, and the Megazord fights (unsuccessfully) to pull him out, a robot brachiosaurus prop with really limited facial articulation manages to convincingly seem terrified.
Power Rangers Megaforce shows us how much of a threat the Armada invasion really is: when Troy attempts to contact Gosei about their victory and Robo Knight's disappearance, Gosei's reaction is a panicked "Rangers, morph now! MORPH! MORPH! MORPH!"
The Originals: Agnes was relieved when she learns that Elijah promised Sophie not to let Klaus kill her. However, her eyes widen in realization with an internal Oh Crap when Elijah suddenly kills the two guys next to her.
Elijah: I promised I wouldn't let Niklaus kill you. I didn't say anything about myself *cue Neck Snap* Nobody messes with my family.
Quantum Leap: In the episode "A Leap for Lisa", Sam leaps into a young Al, who's been charged with a capital crime. After the witness who cleared him in the original timeline gets killed...
Al: Now there's a 96 percent chance I'm convicted. 97 percent! Geez, 98! 99! Sam: For God's sake, stop it. Edward St. John V: 100. Sam:(turns) Edward: Yes, there is a 100 percent certainty that Ensign Calavicci will be found guilty and executed in the gas chamber.
A more mild version is Sam's Once an Episode catchphrase: Whenever he Leaps, he tends to find himself in a not-so-nice position and wondering how he'll deal with it this time. Cue catchphrase: Oh Boy.
Red Dwarf: The climax of the episode Bodyswap featured Rimmer hijacking Lister's body and making a getaway in Starbug. Pursuing Rimmer across the rocky terrain of a barren planet, Lister tells the others to back off and let him go because it's too dangerous. Victoriously taunting the others as they retreat, Rimmer fails to notice that his vessel is about to crash into a cliff-face. As he turns his head, his grin then gives way to our favourite expression.
Kryten gets off an amusing variation in the episode DNA:
"Wait a minute. No. My brain is part organic and therefore it is entirely possible for the machine to transmogrify my physical condition. Engage panic circuits. Panic circuits engaged. BWAAAHAAA!!"
Rimmer has this reaction in the "Inquisitor" episode. Rimmer thinks he's found a way out of being judged by the Inquisitor because of the legitimate point that he might not get a fair hearing. The Inquisitor then explains that to make the hearing as fair as possible, every person's judge will be...
[The Inquisitor opens his helmet, revealing Rimmer's face underneath]
Rimmer: Oh, smeg!
Rimmer!Inquisitor: "Oh smeg!" indeed, matey.
Retro Game Master: Heaven to Hell. This is the name the staff gave to the rather frequent change in facial expression when Arino first celebrates beating the final boss, then hurries back to pick up the controller as the True Final Boss starts eating away at his last life.
Again in Episode 10 when Monroe manages to get several helicopters equipped with miniguns flying.
Topped off in Episode 13 when Miles and the rebels learn that Monroe has obtained a nuclear weapon.
Scrubs: Doctor Cox in the Season 8 finale. He delivers a long speech on how not only is J.D. the best doctor to ever come through Sacred Heart, but is also Doctor Cox's personal friend. This is the moment J.D. reveals he has been standing behind him the whole time. The look on his face is utterly priceless.
Sherlock: An Oh Crap moment occurred for Sherlock at the end of The Great Game when Moriarty is revealed to have John Watson as a hostage. Don't worry, he gets better. Sort of.
Spoofed by Moriarty when Sherlock has a gun pointed a few inches from his face.
This show is packed with these. Standard expression for Chloe / Lana / Victim of the Week whenever they are cornered by the freak of the week, and also for the freak of the week when Clark curb stomps them. Although for Chloe, you'd wonder why she isn't thinking when Clark would come over and save her instead.
Chloe does a serious one when Lois walks in and declares that she is "Faora, wife of Zod."
Major Zod doesn't say anything when he is defeated, but the look on his face as he realises that Clark, who he has just stabbed with a Blue Kryptonite dagger and pushed off a building has outsmarted him and won the fight, is priceless. Instant teleportation ensues.
Another one for Zod before the fight even starts, as he realizes that, oh yeah, Kryptonians possess SUPER HEARING.
Lionel gets one in the episode "Transference." It's bad enough that a riot has broken out in the prison he's at, but he's horrified to see Clark calmly coming for him while everyone's distracted. Clark and Lionel have switched bodies, so Lionel-in-Clark is coming to kill his "old" body so that he can remain in Clark's forever.
Stargate Atlantis: Rodney is very fond of voicing "Oh Crap" word for word, though he usually quickly comes up with some technobabble solution to the problem he's just spotted with the earlier planned idea. His "Oh Crap" expression is hilarious too. Here's a truly epic scene from the second season where it's being delivered by, of all people, Hermiod. Another scene when Mc Kay tries to stand up to two Wraith single-handedly.
The phrase is also said by Sheppard right in the second episode when he sees a big flight of Darts blockading the spacegate who are perfectly capable and willing to blow him out of the sky (or rather, space) if he so much as sneezes near the gate.
In "The Quest, Part 2" Teal'c throws a bundle of C-4 at a dragon, which snaps it out of midair and gulps it down. It goes off in the dragon's stomach to no effect whatsoever. Teal'c just sorta stands there slightly wide-eyed and gulps, which for a guy who is usually The Stoic is hysterical.
Star Trek: Deep Space Nine: In the equally brilliant episode "In the Pale Moonlight" Captain Sisko gets a man out of a Klingon prison to create for him a forgery of a holographic record. When he learns that Garak will explain to him what is expected of him, his reaction speaks volumes:
Star Trek: The Next Generation: The classic episode, "The Best of Both Worlds". The Borg kidnapped Captain Picard and are ready to conquer the galaxy, having turned Picard into their mouthpiece, Locutus of Borg. Riker steels himself and orders the Enterprise to fire its main deflector dish, a jury-rigged Wave Motion Gun capable of vaporizing a small continent. — "Mr. Worf... FIRE." The ship cuts loose with its Doomsday weapon... which does preciselyjack shitagainst the Borg. The moment is beyond words as it slowly dawns on the crew that they've come up against the one enemy they will not defeat. Locutus even taunts them over it:
Locutus: "The knowledge and experience of the human Picard is part of us, now. It has prepared us for all possible courses of action. Your resistance is hopeless...Number One"
In I, Borg, the entire senior staff has one when they realize that the wreckage they are investigating is a Borg vessel, and there's a survivor. Picard is so shocked, he briefly entertains Worf's suggestion that they kill the drone, make its death look like an accident, and get the hell out of there.
That honor-obsessed Worf is the one to suggest that course of action speaks to the horror of the situation.
In the episode where Barclay is introduced, Capt. Picard accidentally calls him "Broccoli". His reaction is quite expressive.
Star Trek: The Original Series: And in the episode Arena Kirk has just crept up on the Gorn and with some difficulty lobs a rock the size of his own head at it. The Gorn is too slow to dodge, and the rock scores a direct hit, with no visible effect whatsoever. Then the Gorn responds by picking up a four-foot diameter boulder of his own...
Kirk gets another of these in "Amok Time" when T'Pau informs him that he has just agreed to fight the hormone-crazedSpock to the death. Spock's reaction at the end when he realizes he's been caught being emotional might count as a comedic example.
The episode "Mirror, Mirror" had the mirror universe Spock warning his Sulu that if he "disappeared," his associates would avenge him, punctuated with "And some of them are Vulcans." Seeing Sulu's eyes go wide in the reaction shot with a musical sting is all you need to know that is one serious threat!
Charlie from "Charlie X" when the Thasians, the alien race who gave him his powers, come to take him back.
Star Trek: Voyager: In the episode "Future's End, Part II," Henry Starling has one just before the Voyager crew stop him from jumping to the future. His ship warns him of an incoming torpedo, he manages one "Uh-oh!" before he explodes.
"Scorpion Part I" has two in quick succession. First, Voyager encounters FIFTEEN Borg cubes. Just one of them managed to destroy 39 ships and kill 11,000 people, and here Voyager comes across a fleet of them. And they pass by without bothering to assimilate or destroy Voyager. A little later, Voyager runs across those same fifteen cubes... as a debris field. Oh Crap really doesn't begin to cover it.
Supernatural: Plenty, what with the traveling the nation fighting monsters and pagan gods and such, and often barely winning.
We get a pretty epic one at the end of season four, because it doesn't get much worse than finding out that you've just accidentally unleashed Lucifer when you were trying to prevent exactly that.
In season five, the gang has gone to considerable effort to get the Colt, which was the Applied Phlebotinum of the first two seasons and will kill anything. They sacrifice two of their own to get into a position to use it on Lucifer. Dean shoots the Devil in the head. Aaaaand...he gets back up. Whoops.
But in the final episode of season five, when Archangel Lucifer tells Sam and Dean he knows they have the one thing that can trap him, in such a confident way as to explain that's not a problem, Dean can't even try to mask this face.
Oh Crap reactions all around at the end of season six. Raphael gets a quiet and terrified one when she realizes that Castiel has absorbed the souls of Purgatory, becoming a new god. Ditto for the brothers and Bobby, who saw the entire thing, and were then told to bow down or be killed.
Castiel: I'm your new God, a better one. So you will bow down, and profess your love, unto me your Lord, or I shall destroy you.
The words are actually spoken in Season 7's "Season 7, Time For A Wedding!" when Dean holds at knifepoint a crossroads demon who's been taking human souls before their contracts are up. Amid Dean's threats, the demon suddenly loses all confidence and mutters "oh, crap." Dean assumes the reaction is in response to him, but a familiar "hello, boys" reveals that Crowley has appeared behind Dean's back. We then hear the muttered "oh, crap" from Dean himself.
Tales from the Crypt: In the episode "Yellow", the cowardly WWI officer who's condemned for deserting his men stands in front of the firing squad, and boldly utters his last words, confident that his C.O. father has replaced the bullets with blanks. Then he notices his father looking away just before the command to fire, and realizes he'd only been told that so he wouldn't disgrace himself by cringing...
Teen Wolf: Scott has one in the pilot when he learns that the werewolf hunter from the forest is the father of the girl he has the hots for.
Stiles has one as well when he realizes that he's surrounded by both Peter Hale AND his human accomplice.
And in Series 19 Episode 4, during the car rugby segment, when the ground is really muddy and slippery, and Clarkson realises that he is going to collide with May, and there's nothing Clarkson can do about it, Clarkson just quietly says "Oh shit."
The franchise's Most Triumphant Example, however (if you can call it that), has to be Richard Hammond's expression during the launch of the Reliant Robin Space Shuttle gradually and steadily transitions from a grin of gleeful, childish eagerness, to dawning realization (this trope) to horrified shock in the space of about 45 seconds.
Torchwood: There are times when it seems the team has perfected these. A great example is the penultimate season two episode "Fragments" when all the team members except Gwen encounter bombs set to go off in mere moments. Cue facials.
Owen Harper's response tops all the others, though:
Owen: Oh, snap.
In the series 1 finale, almost every character has visions of lost loved-ones telling them to open the Rift. Jack is unconvinced, but the rest of the team overpower him. They go outside and find the oh-so-helpful Bilis, who informs them that they have released Abaddon, son of the Beast. They slowly turn around to see this◊ towering over the city. Oh Crap indeed.
Tracker: Nestov gets a pretty epic Oh Crap moment in 'What Lies Beneath'. Mel was always annoyed throughout the series by his repeated hitting on her, and after she discovered her Cirronian heritage, it meant she could use the collector. Cole tosses her the collector so she can snag a fugitive who's closer to her than to Cole himself, and Nestov realizes she's probably going to come for him with it next. (though he talks the two out of collecting him)
Two and a Half Men: At the end of episode #40, titled "Can You Eat Human Flesh with Wooden Teeth?", Alan Harper says "Oh Crap" when he forgets to pick up his ex-wife Judith at the airport. To make matters worse, it was raining outside.
In season 5, Stefan comments to Tessa that he thought the witch Qetsiyah was crazy and insane. Then he gets this reaction upon realizing that Tessa is Qetsiyah (and she's not pleased with the comment).
Veronica Mars: Season 2 has one, when Keith tells Woody: "Most adults keep their hands off other people's children." Steven Guttenberg makes the BEST "Oh crap" face.
Air Crash Investigation: Expressed by various pilots, passengers, and/or air traffic controllers just before the bad stuff goes down.
Perhaps seen most effectively in Crash of the Century, which covers the Tenerife disaster. The First Officer of the Pan-Am flight is positively horrified as he sees the KLM jumbo barreling down the runway towards his plane.
In "Head On Collision", a rail passenger with a view of the track in front of him realizes that his passenger train is about to collide with a freight train head-on.
In "Air France 447: Vanished", the captain has this reaction when he realizes that his co-pilots' diverging inputs to the side-stick controls are leading the plane into a stall.
In Ryan's battle against Wolfbot, despite managing to continually kick him away, Ryan couldn't actually do any real damage to him. Also, when Graybot survived the lightning hand finisher, Ryan was shocked assuming he'd go back to Grimlord's dungeon to recover as Grimlord's top generals often did. But instead he continued to battle and ended up spontaneously self-destructing after awhile.
Usually a bot is weakened by JB and Kaitlin's VR Double Team, but after being hit by it, there was an explosion as to be expected, but Rollbot charged out of the smoke completely unharmed and VERY pissed off (the laser lance finisher took care of that threat just fine, however).
On that note, Mechanoid and Fanbot indicated that it only tickled a bit.
When JB used his laser lance, he'd generally first impale the bot, and the bot would surrender upon being impaled (but get destroyed anyway). Some, however did not surrender, which meant that JB had to react quickly or he was going to get hit again. In fact, against Electrobot it was just to make him lose his balance so he'd fall off his ledge so they could actually fight on equal terrain.
Fanbot not only laughed off the impalement but the subsequent slashing, in fact, the impalement ONLY served the purpose of distracting him enough that his fan motor stopped. But once the robot regained his footing after being tickled he picked up JB who was holding into his (fully powered) laser lance and tossed him a great distance, then prepared to destroy him. The ONLY reason JB was still alive is because Fanbot was very clumsy despite being so ridiculously overpowered. In fact, Professor Hart not only said that JB got lucky (the monster could have easily broken his laser lance with his fan blades, even at full power) but that the Skybase missiles wouldn't hurt him either. So JB had to use the VR Technobazooka on him to destroy him, and then used the laser lance only as personal revenge (even though it still did nothing). Unlike the Mechanoid example, this is also canon in Speilban. In both shows, after the initial run, due to time constraints, the Technobazooka scene was cut, leading to Fanbot suddenly appearing in a different location than when JB summoned the laser lance and the impalement failed and Fanbot suddenly has a huge cloud of white smoke surrounding him that looked like it was caused by something else.
