In One Ear, Out The Other

Go To

After you'd known Christine for any length of time, you found yourself fighting a desire to look into her ear to see if you could spot daylight coming the other way.

The ear drum is a sensory organ within the ear canal and can be damaged if you stick an object deep enough in it. In addition, there's no direct path from one ear to the other inside the head, even if material could get through the eardrums — rather, the ears hook up to the nose and throat via the Eustachian tubes, though the eardrum is designed to be watertight. In an ideal situation, nothing should pass through the ears and enter the throat!

This is not the case in cartoons. In the toon world, the ears are there so sound (or just about anything) can go directly into the brain (or out the other ear if the character has no brain to speak of).

Sometimes, the thing that went into the ear ends up visible in the character's eyeballs, as if they were just windows into his head.

A variation of this trope does not involve physical objects going into the ear, but rather a POV shot of a character's ear showing an unobstructed view through their empty head and out the opposite ear. At least it proves they're not too dense for light to escape them.

If a living creature does this to another character's ears, this overlaps with Orifice Invasion.

See also Hollow-Sounding Head and Who Even Needs a Brain?. Can occasionally overlap with Disability Immunity and Orifice Invasion. Doesn't refer to when things people are saying go metaphorically "in one ear and out the other"; that sense would be covered by Comically Missing the Point or Not Listening to Me, Are You?.

  • An Australian KFC Hot and Spicy ad campaign from the 90s had customers gain the ability to breath fire after eating the spicy chicken. One commerical featured a guy tucking into a bucket of extra hot chicken while his Dumb Blonde girlfriend sitting beside him is completely absorbed in a very cliche sounding soap opera. Without taking her eyes off the screen she asks him what he is eating. He responds by leaning over and blowing softly in her ear causing a jet of flame to shoot straight out of her other ear. As he leans back she blinks, shakes her head slightly, comments that it sounds nice and reaches for a piece herself, still without taking her eyes off the screen. See it here.

  • American artist George Condo has painted several satirical portraits of Queen Elizabeth II, one of which shows her with a carrot lodged through her ears.

    Comic Books 
  • The French comic Les Blondes had a joke around this. In an early volume a Dumb Blonde is listening to some gossip on her cell phone and laughing out loud. Her equally blonde friend asks her what the gossip is and the first blonde tells her to stick her ear next to the first blonde's other ear, allowing her to listen in on the phonecall. It works. A later strip had a similar joke involving an iPod an the two girls sharing a single set of earbuds.
    • The 24th volume has a longer joke where Kim brings a nervous Vanessa along to a Star Wars convention. Kim is dressed in full Jedi robes and carries a toy lightsaber but poor Vanessa lacks any sort of costume and is nearly thrown out. Kim tells the other fans that the "the Force is strong in her [Vanessa's] family" and 'proves' it by turning off the lights and having Vanessa shine a blue flashlight in her left ear... the beam of which naturally shines out Vanessa's right ear, looking like a lightsaber passing harmlessly through her (ala Obi-Wan in Episode IV). The other fans love it and literally fall down in worship of Vanessa, much to her surprise and delight.
    • The 27th volume has Vanessa trying to get water out of her left ear after a shower. She 'loses' two cotton swabs down her left ear, only to discover them coming out her right ear.
  • An early Billy & Buddy page had Boule's dad try to administer some eardrops to Bill. The first ear goes fine, but when he switches to the second ear, the drops in the first start leaking out just at the right time for Boule (and soon Dad as well) to mistake it for this trope.
  • The trope image is a one-panel gag taken from the 1940s Good Humor comics (now in the public domain, readable here.).

    Comic Strips 
  • In an early 1980s Garfield strip, Garfield witnesses a bug flying into Odie's ear... only to come out of the other one. Smiling, he thinks/speaks to himself: "Figures."
    • In a later strip Jon whispers into Odie's ear what he is going to get Garfield for Christmas, only to stop when he notices Garfield listening at Odie's other ear.
  • A 1960s The Perishers strip had Maisie being chased by Wellington with a water pistol. Maisie asked Marlon for help, only to have Wellington squirt the gun into Marlon's ear, straight through his head, into Maisie's face. Marlon, of course, hardly noticed.
  • A 1940s-era political cartoon by Dr. Seuss showed a line of citizens waiting to have Uncle Sam spray a "mental insecticide" into their ear (a teasing reference to Seuss' advertising work for Flit insecticide). Out of the other ear was blown a "Racial Prejudice Bug." The citizen is shocked to realize that such a creature was living in their head.

  • Played with in low budget horror spoof Stan Helsing. After Mia (a Brainless Beauty), does something particularly stupid the irritated hero blows in her ear and lifts up the hair on the other side, pretending he can blow through her head. Except blowing in Mia's ear really does cause a wind whistling-through-empty-space sound and the oblivious Mia looks around nervously for the source of the noise.
    Mia Do you guys hear that?

    Live-Action TV 
  • An episode of Night Gallery has a man in a jungle being tortured by having an earwig tunnel through his head, going through one ear and out the other. He survives, but it leaves eggs inside. Needless to say, the whole thing is biologically wrong.

  • The Outer Limits (1995): In the episode "From Within", a small town is invaded by prehistoric slug-like parasites who crawl into a victim's head through nostrils or earholes and turn them into hedonistic delinquents. A waitress has one slug crawl in her right ear, then much later falls out of her left ear dead, leaving her back to normal. This might have been a mistake, but she did come across as pretty ditzy, so this might have been a stealth pun...
  • In The Pitts, Faith at one point gets a pipe lodged through her head (side to side rather than front to back) at ear level and is completely unharmed (other than the social embarrassment of being a teenage girl with a pipe through her head). At one point, a doctor shines a torch through her pipe and can see out the opposite side.
  • One episode of The Beverly Hillbillies features Granny giving Jethro a physical before he joins the army. At one point she is using a candle to look into his ear then, still looking in the same ear, moves the candle to the other side of his head. She blows in the original ear, snuffing the candle out.

    Music Videos 
  • The Tom Petty and the Heartbreakers music video for "Make It Better (Forget About Me)" has a tiny Petty climb into the ear of a (very confused looking) young blonde woman and play the whole song inside her (mostly empty) head. She eventually uses a q-tip to get rid of them.
  • The Björk music video for "I Miss You" is part live action, part animated (by John Kricfalusi) and features a sexy cartoon Flintstones-like 'cave girl' version of Bjork with a bone going through her ears. This is far from the weirdest sight to appear in the video.

    Print Media 
  • Several versions of this trope turned up over the years in the pages of Weekly World News ranging from a man with transparent brain tissue (so one could shine a light in one ear and have it come out the other), to a young Kansas woman who discovered someone blowing in her ear would result in a breeze coming out the other side to a dimwitted Californian surfer dude who was cleaning his ear with a q-tip, and "not finding much resistance" decided to see how far it could go (right out the other ear it turns out, which the surfer found "way cool").

  • Waxy Wendy (also called Cute Tippi) from the Garbage Pail Kids trading cards is a girl who uses a giant cotton swab to clean both ears simultaneously.

    Video Games 
  • In the Psychonauts game series, someone with their brain removed can still be quite alive, but unable to do much apart from mutter things like "Teevee... hacky sack..." and wander around staring. Looking into the ear of someone without a brain allows you to see right through. (This is not considered a very serious injury, since the usual method of brain removal is exposing someone to super sneezing powder and having them sneeze their brain out through their nose. On the bright side, reinstalling the brain doesn't really require more sophisticated technology that a sturdy funnel.)
  • The depressed inventor in Day of the Tentacle tries to blow his brains out and points his "Bang!" Flag Gun to his left ear but all that happens is the flag coming out the other ear.

How well does it match the trope?
