Wild Card Excuse

"Uhhh... internet."

—Timmy Turner to everyone who asks where he got his stuff from, The Fairly OddParents

The Wild Card Excuse is a Subtrope of Blatant Lies. It often consists of a set of Blatant Lies or a Lame Excuse that is elevated to a Running Gag in the series.

In a game of cards, a wild card can be played in any situation. The wild card excuse is the same way. Late for class? You hit your head. Acting strange? You hit your head. You were seen lighting things on fire with your mind? You hit your... Okay, you get the point. What matters is that the same excuse is always used, no matter the situation, no matter how implausible it is, and it is always believed.

Subtrope of Blatant Lies. Supertrope to Foreigner Excuse. Compare Global Ignorance, Bad Liar, It's for a Book. Contrast Lame Excuse, Hurricane of Excuses, Suspiciously Specific Denial. See also Excuse Plot, and the actual Wild Card.

Not to be confused with a reason to read the early superhero works of George R. R. Martin.

Examples of Wild Card Excuse include:

Anime and Manga

The World God Only Knows is the Trope Namer, where Elsee frequently tries to excuse Keima's weird behavior by saying he's been playing too many video games, and a caption in chapter 83 calls this the "wild-card excuse".
Mahou Sensei Negima: The Mages Hand Wave things like people flying, shooting fireballs, or giant demon mecha with "It's CGI."
- This one actually makes a little sense: The original Japanese phrase means "special effects," which includes CGI, but also fireworks and other stagecraft. But somebody translated it as CGI on accident, and the other translators thought it was funny enough to keep.
In the Webtoon Kubera, Fire God Agni, doing his best to disguise himself, tends to get critically close to revealing his secret to our Idiot Hero Kubera. However, whenever something strange happens, he credits to his jumper. That includes surviving her Megaton Punch and spontaneously combusting.
Prince of Tennis: Ryoma's excuse for being late: "I was helping a pregnant woman to the hospital."
In Fairy Tail, Happy's answer to questions such as "Why are you blue?", "Why can you fly?", or "How come you can talk?" is always "Because I'm a cat!" cheerfully and likely intentionally ignoring the fact that these questions are due to the fact that he is a cat.
Ouran High School Host Club handwaves such questions as "Why is there suddenly a piano there?" with "It's the music room!" This is perfectly reasonable - of course a piano would be in the music room, albeit hidden by a convenient curtain - until a later episode, in which the same excuse is used to explain away the presence of a cage that drops from the ceiling.
- Actually, when the cage appears, the line is something like "Why is there a cage here? Isn't this a music room?". The piano appears at the end, and the punchline is: "Why is there a piano here?" "Well, it is a music room, after all."
School Rumble: "... cause this is the Tea club, after all."
In Detective Conan, Conan often blurts out smart observations in a crime scene in front of the grownups. His excuse of knowing this? He watches a lot of television hiding the fact he's a 17-year-old Teen Genius inside a 7-year-old body.

Fan Works

Shirou of In Flight, every time someone calls him on anything strange about him. Eventually his flock start completing the sentence for him.

Shirou: Legacy of a misspent youth.

In Oh God Not Again, anytime a character asks Harry how he knows seemingly impossible things.

Harry: My psychic scar told me.

Literature

In Everworld the characters often pretend to be traveling minstrels as a cover for the fact that they're from an alternate dimension
Terry Pratchett lampshades this one in the Johnny Maxwell Trilogy.

A project. If Saddam Hussein had said he was doing a project on Kuwait, the Gulf War might never have happened.

Discworld:
- In Interesting Times, Rincewind visits the Agatean Empire, where foreigners are routinely executed. He's advised to tell anyone who gets suspicious that he's from Bes Pelargic, an Agatean town looked down on by everyone else for being a bit weird.
- Likewise, when the Patrician, Nobby and Colon are undercover as Klatchians in Jingo, Sgt Colon is explained as being from Um, a town proverbial for stupidity. Every time someone gets suspicious about him (he doesn't know what a minaret is, he's unfamiliar with couscous, he's surprised by a flying carpet), the Patrician deftly turns it into an Um joke, and everyone laughs and relaxes.
In the first book of the Song of the Lioness series, Alanna always uses "I fell down" to explain her black eyes, and broken bones, and other conspicuous injuries obviously gotten from fighting. This is Justified in that this is the traditional response for brawling pages.

Live-Action TV

In Sliders, whenever the team lands on a new world and has to explain why they don't know what's going on, they use the excuse "We're from Canada." We've hardly ever seen it fail. Although one time they had to pretend to be illegal immigrants from Canada the entire episode, who had snuck south into Mexico for work. (Thanks to the non-existence of America in the middle, and Mexico ending up with California.)
- That gag may have been used because the show originally filmed in Vancouver although set in San Francisco.
Buffy the Vampire Slayer mostly averted this, our heroes generally coming up with new, individualized (if implausible) excuses each time. On the other hand, Sunnydale's police department (when not suffering from Sunnydale Syndrome) usually covered up monster attacks by explaining that it was "gangs on PCP."
Used often in Smallville during the earlier seasons, when any questions Clark Kent was asked about his interest in the caves or any Native American symbols that were related to his Kryptonian heritage were met with "It's for a term paper" — to the point where Lex Luthor himself actually lampshades it later.
A variation in Doctor Who, the question being "Who are you?" and the answer being "I'm the Doctor.", rarely yielding any further questions.
- There are sometimes further questions, but very rarely answers, at least none that are directly relevant.
On Lost, mentioning Canada is always a clue that the speaker is lying. Fugitive Kate tells Ray she's Canadian. Ethan claims to be from Ontario. The Others believe Bonnie and Greta are on assignment in Canada, not jamming signals in the Looking Glass Station. In "The Other 48 Days," Nathan tells Ana-Lucia he's from Canada, which is probably true, but the audience is meant to think it's a lie because Ethan said the same thing.
Saturday Night Live - The Coneheads handwave their weirdness by claiming to be from France.
Fawlty Towers: Manuel being from Barcelona. It explains his bad English. It fails to explain anything else.
Supernatural has a minor variation: The brothers have fake identities every case (FBI agents, doctors, etc), and stick with that for the entirety of the episode—which makes sense, considering they're stuck in a small town. This has led to truly ridiculous claims, such as managing to get everything for a case by being health inspectors.

Naked Woman: Wh-what are you and that kid doing in the women's showers?
Sam: Don't worry, ma'am. I'm with the health department.

One episode of Scrubs had Jordan repeatedly justifying her Jerkass tendancies with "My parents were mean to me". Everyone immediately accepts this as a sufficient explanation. At one point she even says it out loud in response to something she was merely thinking. And of course, it turns out to be a lie anyway.
The X-Files: In Bad Blood: "We were drugged."
Kelly Kapoor in the American version of The Office has a melodramatic wild card up her sleeve:

Michael: You cannot say "I was raped" and expect all your problems to go away Kelly, not again. Don't keep doing that.

Video Games

Near the beginning of Final Fantasy X, Tidus is advised to say "I got too close to Sin's toxin" to cover up his ignorance of life in Spira.

Visual Novels

In Princess Waltz, Liliana uses "I lived abroad" to explain how she was able to jump out of a second-story window with a friend on her back without injury.

Suzuku: Ah, that explains it.
Nishimoto: That's someone who lived abroad for you.

Web Comics

xkcd has "my code's compiling" (see also Alt Text).

Web Original

In the Reincarnation Fantasy web novel Tori Transmigrated, Tori (once forty-year-old Tori Felix, now teenaged noble Victoria de Guevera) uses "I read it in an old, obscure book" as her all-purpose explanation for any aphorism, insight or idea from Earth she might come out with.

Western Animation

The Fairly OddParents: A Running Gag response earlier on happens every time Timmy is asked where he got his wished-for stuff from. Namely the quick response "Internet". See also the page quote.
- One episode subverts this Trope:

Dad: [seeing that Timmy's room is full of stuff that he hasn't bought for him] "Young man, where did you get all these nice things?"
Timmy: "Uh...Internet?"
Dad: "And where did you get Internet?"
Timmy: "Uh...uh..."
Dad: [gasps] "He's stammering! Our son is the Wall-2-Wall-Mart shoplifter!" [screams like a girl]
Timmy: "What?! You don't think I stole this stuff, do you?"
Dad: [screams like a girl again]
Timmy: "That's a yes...but I didn't do it!"
Dad: [screams like a girl again then passes out]
Mom: "That's it, young man, you know you're not supposed to make your father scream like a girl three times in one day!"

- In one episode, while trying to explain why he was suddenly rich, he tried both an inheritance claim, and the usual claim, before settling on "I inherited the Internet!"
  - That particular example eventually becomes a subversion, as a later episode that follows the friends he told this to has them not buying it.
- The peak, however, has to be Superman-esque HEAT VISION being accepted as coming from the Internet... before the Internet existed.
- Weirdness is turned Up to Eleven when Vicky wants to get married to Chip Skylark. Where does she find a justice of the peace willing to marry a pop idol to his crazed teenage fan against his will? "On the Internet!"... Which implies that you really can get anything and everything on the Internet.
Johnny Test: Dukey the speaking dog is always "a kid with a rare hair disorder".
In the "Knifin' Around" episode of Space Ghost Coast to Coast featuring Thom Yorke from Radiohead, Space Ghost takes a break from the interview to discretely reveal to his director, Moltar, the fact that he has illegally copied Radiohead CDs. When Yorke appears to be listening in, Space Ghost covers by saying, "Don't look at me... we're talking about dragons!"

Real Life

Weather balloons have bit of notoriety amongst UFO enthusiasts as it's probably the most often used explanation ever for UFO sightings even against testimony of people who have claimed to flew next to it.
- Well, Secret Experimental Aircraft Tests have to be kept Secret.
- And it doesn't help that during the Cold War there really was an Air Force project focused on what were basically highly secret weather balloons (it involved detecting hidden nuclear testing), and that the Air Force took a while getting the hang of covering up the project's existence. While the convenient public perception that they were really covering up alien contacts evidently came about by incompetence rather than planning, the result worked... and the connection stuck around.
