I Can Explain

"HEY, FRANK! Whaddaya say when your mom catches you in your room with a jar of peanut butter and the family dog?"

- Audience member at The Rocky Horror Picture Show.

"Argit: No, please buddy! Don't kill me! I can explain! Argit: ANYTHING!"
 * Explain WHAT?

- Ben 10: Ultimate Alien

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.

Invariably, 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 Clark Kenting to protect the secret.

A Discredited Trope as the line is rarely played straight nowadays. And considered the number of times its been parodied/subverted, its well on its way to be a Dead Horse Trope. 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 Not What It Looks Like.

Film
"Tony Stark: Let's face it, this isn't the worst thing you've caught me doing."
 * Subverted heavily in The Usual Suspects, where.
 * Subverted in Iron Man when Pepper walks in on Tony apparently being molested by robots:

"Frank: I can explain... Audience: This better be good, you got killed the last time."
 * Said by Dr. Frank N Furter in The Rocky Horror Picture Show 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.

"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..."
 * The Mask:

"Maddy: You know, I thought I was the liar. Sullivan: Hey, I can explain that!"
 * The Departed when Maddy, the psychiatrist, finds out Sullivan working for Costello.

Literature

 * Making Money 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 Summon Bigger Fish 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.)

Live-Action TV
"Sam: I can explain... actually, no I can't."
 * A primary Catch Phrase on Get Smart subverts this: "I can explain nothing!"
 * Almost a Catch Phrase for Major Nelson on I Dream of Jeannie, 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 Supernatural, a priest disturbs Sam as he's performing a seance in the church basement.

"General: Can you explain to me why several witnesses put you people at a restaurant in town last night? Daniel (interrupting Jack): Sir, I can explain everything! (Pauses) No, I can't."
 * Much British humor (Fawlty Towers, Mr. Bean, and Jeeves and Wooster 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.
 * Stargate SG-1 episode "Upgrades". The protagonists are specifically told to remain on base by the general and promptly disobey their orders due to their superpower-giving and super-stupid making armbands. This leads to the following exchange:

"Blackadder: I can explain everything, sir! Melchett: Can you, Blackadder? Can you? Blackadder: Well...no, sir."
 * From 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":

"Baldrick: I think I can explain, sir. Blackadder: Can you, Baldrick? (Beat) Baldrick: No."
 * 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.

"Drake: Oh my God! Josh: I can explain! Drake: Oh my God! Josh: I can explain!"
 * 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."
 * 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, completly 'faced, wearing a cardinals 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 Father Ted 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 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 a recent episode of 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. Word of God says that he used the phrase a lot during their marriage.
 * Drake and Josh pilot episode has this when the former caughts the latter dressing up like a woman:

"Jeff: I can explain. I'm a teacher. Wait, that's worse than the truth. I'm a student."
 * Community: Jeff when noticed by one of his former lawyer buddies, has to come up with an explanation on the spot.

"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."
 * 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.
 * In the 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, Jerry decides to mess with George, leading to this:


 * El Chavo del Ocho: Whenever Dona 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.

 * Calvin and Hobbes 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 Sweats him and he panics as he tries to explain what he thinks Miss Wormwood told her:

"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?..."
 * 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:


 * On another instance, Peter, after his mother looks under his mattress and tells him she found something, insists that he reads the magazines there for the articles until she shows him that she found his baseball glove there.
