->''"HEY, FRANK! Whaddaya say when your mom catches you in your room with a jar of peanut butter and the family dog?"''
-->-- [[AudienceParticipation Audience member]] at ''Film/TheRockyHorrorPictureShow''

A character with a guilty conscience reacts to the appearance of an authority figure with a cry of "Wait! I can explain!" and launches into an explanation of how whatever-it-was wasn't their fault.

Often, it turns out that the authority figure really wanted to talk to them about something else, and wouldn't even have known about whatever-it-was if they hadn't tried to explain.

The next step in the evolution of this trope is also common: a parent will confront their kid in a vague way, and the kid will confess to whatever he or she has done. The parent either knew the kid was up to something, but had little idea of what the specifics were; or, the parent was just making a routine surprise inspection.

Alternately, a phrase spoken by someone whose Masquerade's about to be blown who's about to make with some quick ClarkKenting to protect the secret.

A DiscreditedTrope as the line is rarely played straight nowadays. And considered the number of times its been parodied/subverted, it's well on its way to be a DeadHorseTrope. As such, a common subversion is for the character in question to deliver this line... then resignedly admit that no, actually they ''can't'' explain it.

Often caused by the situation being NotWhatItLooksLike. See also the cousin Trope NoodleIncident.

[[folder: Anime and Manga]]

* Mana in ''Anime/DokiDokiPrecure'' said this when her friend, Alice, caught her and Rikka's transformation.
* ''{{Higurashi No Naku Koro Ni}}'': Keiichi to Satoko, during the Curse Killing Arc. Satoko arrives back on the scene just in time to see [[spoiler:Keiichi holding a bloody axe, with Rika's mutilated body on the ground next to him]]. Understandably, she's a little more than distressed at this. Keiichi proceeds to chase her and yell variations of this and NotWhatItLooksLike at her. [[spoiler:He really didn't do it. He was just holding the IdiotBall at the time]].
[[/folder]]

[[folder: FanWorks]]
* In the ''StarTrekTheOriginalSeries'' fanfic ''FanFic/OnceUponAFarmhouse'', Kirk says this word for word to Amanda when he realizes she caught him and Spock sneaking out. His explanation, however, is mostly, "It was my fault, not his."
[[/folder]]

[[folder: Film - Animated]]
* In ''Disney/{{Aladdin}}'' just after his treasonous plot against the Sultan has been revealed, Jafar tries saying "All this can be explained." Exactly ''how'' is a mystery for the ages.
* At the end of ''WesternAnimation/{{Balto}}'', this forms part of Steele's HumiliationConga.
-->'''Steele''': You guys weren't there, so you don't--wait a minute, guys! Wait just a second...please!
* ''UltimateAvengers'' has Bruce Banner's plot of using the Super Soldier Serum on himself so he could control the Hulk has been discovered so he gives out this explanation before being pinned down by Nick Fury.
[[/folder]]

[[folder: Film - Live-Action]]
* Subverted heavily in ''Film/TheUsualSuspects'', where [[spoiler:Verbal's attempts to evade giving information to the police turn out to be an elaborate strategy to get the police to believe him when he actually does provide (wrong) information]].
* Subverted in ''Film/IronMan'' when Pepper walks in on Tony apparently being molested by robots:
-->'''Tony Stark''': Let's face it, this [[NoodleIncident isn't the worst thing you've caught me doing.]]
* Said by [[TimCurry Dr. Frank N Furter]] in ''Film/TheRockyHorrorPictureShow'' before he sings his final song ("I'm Going Home"). Unfortunately for him, Riff Raff and Magenta don't buy his story and promptly shoot him.
* ''Film/TheMask'':
-->'''Stanley Ipkiss''': Wait, I can explain everything!\\
'''Lt. Kellaway''': Oh yeah? You can explain everything? ''[gets the rubber mask from the jacket]'' Explain ''this''.\\
'''Stanley Ipkiss''': Um...
** It should be noted, that was a ''fake'' mask the BigBad slipped into Stanley's jacket to make him look like a liar.
* ''TheDeparted'' when Maddy, the psychiatrist, finds out Sullivan working for Costello.
-->'''Maddy''': You know, I thought I was the liar.
-->'''Sullivan''': Hey, I can explain that!
* Played for laughs in ''Film/TheBluesBrothers'' where the 'explanation' turns out to be a series of increasingly unlikely excuses. Amazingly enough they do the job and let the brothers make their escape.
* The [[{{Film/Annie1982}} 1982]] and [[{{Film/Annie1999}} 1999]] film versions of ''Annie'' include the scene from the musical where Miss Hannigan defends herself regarding Annie's escape attempt, thinking that Grace Farrell came to the orphanage to investigate that incident.
[[/folder]]

[[folder: Literature]]
* ''Discworld/MakingMoney'' features Moist von Lipwig's first words to Lord Vetinari when he has been summoned as "look, I can explain." Vetinari's actually summoned him for something else entirely, but Moist does have to spend some time why there were mongooses in the posting boxes. (Someone had come up with the brilliant idea of SummonBiggerFish to take care of snakes, who were introduced to eat the toads, who were introduced to eat the snails, who were eating the glue on the postage stamps.)
* In the ''Literature/HankTheCowdog'' book "The Case of the Measled Cowboy", Hank begins to rehearse his explanation to the woman of the house, Sally May, for the tremendous mess that he and her son made in her absence. Subverted in that he admits he can't get any farther than "I can explain."
[[/folder]]

[[folder: Live Action TV]]
* Several times in ''Series/{{Smallville}}'':
** Lex Luthor, in an attempt to convince a female friend that she deserves better, got her to a nightclub, where she found the man she is engaged with when he is supposed to be on a business trip. The guy says the line repeatedly. To quote a reviewer, "If you are just going to say that, it is clear that you can't explain s***."
** When Chloe and Clark are both [[NotHimself not themselves]], they do some intense making out right under Lana's nose. When Chloe strips Clark, the [[spoiler:red kryptonite]] is removed and he is back to normal. He says this to Lana who slams the door in his face after NotWhatItLooksLike. He can't explain anyway as he must save Chloe before she get herself killed [[spoiler:as some parasite makes her dangerously implusive]], and Clark can't tell Lana about the [[spoiler:red kryptonite]] anyway.
** Lana once says this when Lex finds out she stole his car. There is absolutely nothing she could explain, really.
** Jimmy says this when Chloe, who is at the time his girlfriend, walk in on [[{{Supergirl}} Kara]] and him alone but not doing anything suspicious. Chloe's paranoia is somewhat justified given her [[spoiler:meteor infection]].
** Clark tells this to Lois when he "accidentally" left her in the rain for three hours.
** And again in ''Echo'' when he didn't show up [[spoiler:for a date.]]
** And ''again'' in ''Escape'' when Lois caught him [[spoiler:[[CrowningMomentOfFunny in the shower with a naked Chloe.]]]]
* A primary CatchPhrase on ''Series/GetSmart'' subverts this: "I can explain ''nothing''!"
* Almost a CatchPhrase for Major Nelson on ''Series/IDreamOfJeannie'', to the point where he once said, "I'm not sure what I did, sir, but I'm positive I have an explanation for it."
* In an episode of ''Series/{{Supernatural}}'', a priest disturbs Sam as he's performing a seance in the church basement.
--> '''Sam:''' I can explain... actually, no I can't.
** A couple of Hunters discover Sam's role in [[spoiler:starting the Apocalypse]] and declare they're going to blow his head off. Sam says he can explain, then flounders because he is in fact guilty as hell. So they kill him. [[DeathIsCheap Again.]]
* Much British humor (''Series/FawltyTowers'', ''Series/MrBean'', and ''Series/JeevesAndWooster'' being prime examples) is based on this sort of thing, although the three examples are set about it in different ways. Basil Fawlty comes up with an explanation that is even more unbelievable than the truth, Bean just pretends nothing is happening, and Bertie Wooster gets too nervous to explain.
* ''Series/StargateSG1'' episode "Upgrades". The protagonists are specifically told to remain on base by the general and promptly disobey their orders due to [[ImportedAlienPhlebotinum their superpower-giving and super-stupid making armbands]]. This leads to the following exchange:
-->'''General:''' Can you explain to me why several witnesses put you people at a restaurant in town last night?\\
'''[[AdventurerArchaeologist Daniel]]''' (interrupting Jack): Sir, I can explain everything! (Pauses) No, I can't.
* From ''Series/{{BlackAdder}} Goes Forth'', Blackadder assuming that his commanding officer has realized his glamorous showgirl is actually a "strapping six-footer from the rough end of the trenches":
-->'''Blackadder:''' I can explain everything, sir!\\
'''Melchett:''' Can you, Blackadder? Can you?\\
'''Blackadder:''' Well...no, sir.
** And of course, he thinks Blackadder is saying he can't explain "the mystery of love" and he remains blissfully unaware that the woman he loves is one of his underlings.
** Another one earlier in the same series; Blackadder has been repreived from his death sentence by George's uncle, and then learnt that George and Baldrick got drunk and never actually ''asked'' his uncle to do so.
--->'''Baldrick''': I think I can explain, sir.\\
'''Blackadder''': Can you, Baldrick?\\
({{Beat}})\\
'''Baldrick''': No.
* The earlier ''Blackadder II'' had a similar gag where Blackadder is entertaining his fiercely Puritanical aunt and uncle while simultaneously holding a drinking competition. Things seem to be going well, until one of the drunks (dressed as a monk) bursts into the room, vomits in the fireplace, and leaves, saying "Great booze-up, Edmund!" When asked if he can explain, Blackadder spends the next minute staring into space and working his jaw as he tries to come up with an explanation, then finally says "...Yes I can."
** [[CrowningMomentOfAwesome And he does.]]
** Incidentally, the man really was a monk, although one of extremely ill repute. Considering that puritans couldn't stand monastical system, that probably didn't do Edmund any favours, either.
** Later in the same episode Blackadder returns to the room, completely 'faced, wearing a cardinal's hat, fake breasts and a feather up his bum. When his Aunt demands he explains, he just pauses a second and replies "....I ''can't''. Not just like that."
* {{Lampshaded}} in an episode of ''Series/FatherTed'' when Ted is caught with a stolen whistle and ''attempts'' to explain everything with a hastily-improvised sob story about a crippled boy attempting to train a horse to win the Grand National. He stops halfway through when Dougal reveals that they found out the real culprit while Ted was out of the room.
** Played entirely straight, however, in "Are You Right There, Father Ted?", featuring the collector of Nazi memorabilia who has left his collection to Ted in his will for various farcial reasons - a collection Mrs Doyle has put up in the house, believing it to be the expected delivery of new furniture - just before Ted returns from the pub with the inhabitants of the island's Chinatown. Uses the seemingly common "I can explain everything... Actually, no, I can't" delivery.
* Subverted in ''Series/{{Coupling}}'' when Susan accuses her ex Patrick of filming them in bed together and keeping the video. Patrick responds with "I can explain.....Yes I did".
* Blurted by Nate in an episode of ''Series/{{Leverage}}''. When his ex-wife finds him after he came to Kiev when he heard she was in trouble, he speaks this line. It's also used in the first season finale when his ex-wife finds out that he was spying on her. WordOfGod says that he [[CatchPhrase used the phrase a lot]] during their marriage.
* ''Series/DrakeAndJosh'' pilot episode has this when the former caughts the latter dressing up like a woman:
-->'''Drake''': Oh my God!
-->'''Josh''': I can explain!
-->'''Drake''': Oh my God!
-->'''Josh''': I can explain!
* ''Series/{{Community}}'': Jeff when noticed by one of his former lawyer buddies, has to come up with an explanation on the spot.
-->'''Jeff:''' I can explain. I'm a teacher. Wait, that's worse than the truth. I'm a student.
** Later in the same episode, Troy says it verbatim to a janitor who catches him in someone else's office. Then he plays for time by insisting "Let me explain!" to the still silent janitor, and then stands there awkwardly, unable to think of anything, until Annie comes in and chloroforms him.
** Also, in the BottleEpisode, when everyone discovers [[ItMakesSenseInContext Abed's log of the girls' periods]] and begin to get distressed:
--> Abed: Wait, I can explain! (beat) [[GenreSavvy Oh, I thought you were all just going to yell over me.]] I really can explain.
* In the ''Series/{{Seinfeld}}'' episode "The Heart Attack", George is in the hospital, thinking he's had a heart attack. After learning from the doctor that he didn't, [[ComedicSociopathy Jerry decides to mess with George]], leading to this:
-->'''George:''' Kill me now. I'm begging you. Let's just get it over with. Be a pal. Just take the pillow and put it over my face.
-->'''Jerry:''' ''(Nonchalant)'' Well, uh, what, kinda like this? ''(Forces the pillow down on George's face)''
-->'''George:''' WHAT ARE YOU DOING?! WHAT ARE YOU, CRAZY?! ''(Elaine walks in)''
-->'''Elaine:''' JERRY! (Jerry stops)
-->'''Jerry:''' ''(Mock guilt)'' Elaine...what are ''you'' doing here? ''(Removes pillow)''
-->'''George:''' Jerkoff.
* ''Series/ElChavoDelOcho'':
** Whenever Doña Florinda assumes Don Ramón did or tried to do something to her son, she won't listen to whatever explanation he's got to offer.
** Also, Don Ramón once told his daughter Professor Jirafales was coming to visit him. Her immediate reaction was loudly pleading him not to believe anything Professor Jirafales says. Don Ramón asked her what he'd say and she realized she spoke too much.
* ''Series/{{Friends}}''
-->'''Phoebe:''' Oh my God, you're getting a massage? You never let me massage you!
-->'''Monica:''' Phoebe, I can explain! You see...God, I gotta get better at lying.
* ''Series/{{NCIS}}'' had a scene where Tony was doing a horse impression and suddenly realized from everyone's expressions that Director Vance was [[RightBehindMe right behind him]]:
-->'''Tony:''' ''(without daring to turn and look)'' I can explain, sir.\\
'''Vance:''' Sit down, Doctor[[note]]He's accompanied by an NCIS psychiatrist[[/note]], this should be good.
[[/folder]]

[[folder: Newspaper Comics]]
* ''ComicStrip/CalvinAndHobbes'' used this trope when Calvin's mother went for an interview with his teacher, Miss Wormwood. Calvin begins packing a suitcase to run away. When his mother comes back and tries to talk to him, she unknowingly {{Perp Sweat}}s him and he panics as he tries to explain what he thinks Miss Wormwood told her:
-->'''Calvin's Mom''': Calvin, I...
-->'''Calvin''': Yike! You're home! I didn't even finish pack...that is...um...lies! Everything Miss Wormwood said about me was a lie! She just doesn't like me! She hates little boys! It's not my fault! I'm not to blame! She told you about the [[NoodleIncident noodles]], right? It wasn't me! Nobody saw me! I was framed! I wouldn't do anything like that! I'm innocent, I tell you!
-->'''Calvin's Mom''': What noodles?
-->'''Calvin''': Oh! Uh...noodles? Ha ha...you must have heard wrong. I didn't say noodles.
* ''ComicStrip/FoxTrot'' also used this in a strip where Peter punches a guy at school for making a joke about Denise and is told his parents will be called:
-->'''Peter''' (''worried''): Hi.
-->'''Andy''': Peter, the school called me today.
-->'''Peter''': Look, I know what you're going to say. Fighting is wrong. I know that. It was a momentary lapse. It won't happen again. I'll have to serve detention, but Mr. Krimpshaw says he may not put it on my permanent record. I'm sorry, I'm sorry, I'm sorry. I was an idiot, all right?!
-->'''Andy''': They called to say someone found your wallet.
-->'''Peter''' (''thinking''): "Was" nothing.
-->'''Andy''': Now, then. What's all this about a fight?...
** On another instance, Peter, after his mother looks under his mattress and tells him she found something, insists that [[IReadItForTheArticles he reads the magazines there for the articles]] until she shows him that she found his baseball glove there.
[[/folder]]

[[folder: Radio]]
* Parodied in ''Radio/{{Nebulous}}'', where Nebulous's underling's try to explain their attempted DyingDeclarationOfLove, but Nebulous simply shrugs the explanation off, saying "if you got drunk and indulged in foreplay, I'm sure you had a damn good reason."
* In practically every episode of ''NavyLark'', CPO Pertwee is caught out ... exclaims, "I can explain!" ... and often does.

[[folder: Webcomics]]
* In ''[[http://tmi-comic.com/ Too Much Information]]'', when Ace (who occasionally [[TheAce live up to his name]]) is making out with a strappin' Scottish lass on the doorstep, and her grandmother walks in on them, his quick "I can explain!" is answered by a dry "Be fun tae see ye try..." before the CoolOldLady reveals that she's got no objections whatsoever.
* In ''Webcomic/KevinAndKell'', Corrie [[AvertedTrope narrowly avoids falling into this twice]] regarding her being a sheep disguised as a wolf. When [[http://www.kevinandkell.com/2000/kk0909.html Fiona mentions that she knows her secret]]. Corrie assumes that Fiona knows her true species, and is about to remove her wolfskin when Fiona tells her that she actually "knows" that she's Ralph's daughter (which turns out to be true, unbeknownst to either). Later on, [[http://www.kevinandkell.com/2002/kk0110.html when the power goes out at a slumber party]], Fiona and Rhonda tell her she's hiding something, but before she can articulate an answer, they say that she's wearing ''Bruno's sheepskin'', (he sometimes wears her on his back, but later wears a skin made out of her wool).

[[folder: Western Animation]]
* ''WesternAnimation/DannyPhantom'': Danny's response after the strange events of the FreeTheFrogs episode? "I can explain... actually, I really can't."
** Or, when his family (mostly Jazz) comments on his odd behavior, Danny's Response is "ITS A LIE, [[BlatantLies I'M NOT]] [[SuspiciouslySpecificDenial A GHOST!]]" Thankfully, Jazz just figured he'd gotten a girlfriend.
* Twice in the episode "Prehibernation Week" of ''WesternAnimation/SpongeBobSquarePants'', an ordinarily normal-looking fish is revealed to apparently wear Osh-Kosh overalls, a beanie, and a giant lollipop underneath his regular clothes (well, okay, the second time Sandy just ripped up a building from its foundation and revealed the fish in the kiddy clothes, but anyway).

As Jack is trying to free her, he says he can explain everything--then stops, and goes, "Wait, I already did."
