->''"After you'd known [[BrainlessBeauty 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."''
-->-- '''Terry Pratchett''', ''Discworld/{{Maskerade}}''

The ear drum is a sensory organ within the ear canal, and can be damaged if you stick an object deep enough in it. 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 varation of this trope does not involve physical objects ''going'' into the ear, but rather a POV shot of a character's ear showing an unobsructed view through their empty head and out the opposite ear. At least it proves they're not too [[Pun dense]] for [[UsefulNotes/BlackHoles light to escape them]].

If a living creature does this to another character's ears this overlaps with OrificeInvasion

See also HollowSoundingHead and WhoEvenNeedsABrain. Can occasionally overlap with DisabilityImmunity and OrificeInvasion. Doesn't refer to when things people are ''saying'' go metaphorically "in one ear and out the other"; that sense would be covered by ComicallyMissingThePoint or NotListeningToMeAreYou.

[[AC: Comic Books]]
* The French comic ''ComicBook/LesBlondes'' had a joke around this. A DumbBlonde 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.

[[AC: Comedy]]
* Many DumbBlonde jokes feature a variation on this trope, including the page image and the commercial below.

[[AC: Commercials]]
* An Australian KFC Hot and Spicy ad campaign from the 90s had customers gain the [[FireBreathingDiner ability to breath fire]] after eating the spicy chicken. One commerical featured a guy tucking into a bucket of extra hot chicken while his DumbBlonde 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 ([[http://www.youtube.com/watch?v=uaA8Xg7Z0UA see it here]].)

[[AC: Film - Live Action]]
* In the first ''Film/HotShots'' film, Admiral Benson demonstrates this with a handkerchief through the ears, explaining it as a result of one of his [[RunningGag many war wounds]].
** And don't forget the movie poster.
* In ''Film/LoadedWeapon1'', when MsFanservice asks TheHero to "blow in my ear," doing so results in a hollow jug-sound, her hair covering her other ear billowing in the breeze, and a candle by her head being snuffed out.
* Played with in low budget horror spoof ''Film/StanHelsing''. After Mia (a BrainlessBeauty), 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?''
* Happens in ''Film/TheLivingDaylights''. Just watch it [[http://www.youtube.com/watch?v=QMS-Fe9xXXc here]]. [[spoiler:[[DepthDeception It's just a perspective effect]].]]
* In the first ScaryMovie, this happens to Ray. [[{{Squick}} With a penis.]]
* Years later in ''Dance Flick'' Shawn Wayans (who played Ray) is on the giving rather than recieving end: he seductively sticks his OverlyLongTongue into his girlfriend's ears and the tip of his tongue comes out her other ear (the girlfriend clearly enjoys the experience).
** This gag with the tongue in ear has also been used in ''Film/WrongfullyAccused'', ''Jane Austens Mafia'', and a ''Series/NotTheNineOClockNews'' sketch.
* Happens a few times in ''Film/TheThreeStooges''. For example, in one episode Moe throws a feather duster through Shemp's ears and has to help him pull it out.
* The [[http://24.media.tumblr.com/4c9147b806414d015c1618b7f63f9a8a/tumblr_mka8od2b7q1rthgz2o1_1280.jpg?.jpg poster]] for ''ScaryMovie V'' has a devilish looking Katrina Bowden sticks her tongue into Sarah Hyland's right ear, with the forked tip flickering playfully out the left ear (Hyland's expression while this is going on is hilarious.)
* Happens in French comedy ''La folie des grandeurs'' (a parody of Victor Hugo's ''Ruy Blas''), where Don Salluste's servant attempts to dry his master's ear after his bath, and ends up pulling the towel from the other ear.
* A BlackComedy example in ''FreddysDeadTheFinalNightmare''. Freddy torments a deaf teen named Carlos by sticking a very long q-tip so far into his ear that it pops out Carlos' opposite ear.
* In the 1953 Creator/BobHope film ''Film/OffLimits'' Mickey Rooney is being evaluated for Army service, a doctor uses his penlight to examine Rooney's ears and Hope holds his palm up at the other side to show the light is going straight through unimpeded.
-->'''Bob Hope''': ''Looks like this man is officer material!''
* One of the [[http://static.tvtropes.org/pmwiki/pub/images/heathers_heathers.png publicity shots]] for ''Film/{{Heathers}}'' has Heather McNamara whispering into Heather Chandler's right ear, while Heather Duke clings to Chandler's left shoulder, leaning close to Chandler's left ear to listen in.

[[AC: Films - Animated]]
* [[Film/WhoFramedRogerRabbit Roger Rabbit]] scratches through his ears with a file.

* In ''Film/SpaceJam'', doctor Daffy examines Michael Jordan's ear and is able to see Bugs through the other ear.
* [[Disney/SnowWhiteAndTheSevenDwarfs Dopey]] clears water out of his ears by ''blowing'' it out.
* In ''Disney/{{Pinocchio}}'', Gideon the cat tries to listen to what the coachman is whispering to Honest John by putting his ear to John's other ear. When he can't hear anything, he cleans out the ear with his finger. He also earns bonus points by plugging up his own other ear to make sure nothing comes out.

* An old episode of ''NightGallery'' had a man in a jungle being tortured by having an earwig tunnel through his head, going through one ear and out the other. He survived, but [[spoiler: it left eggs inside]]. Needless to say, the whole thing was biologically wrong.
* In an episode of ''Series/SabrinaTheTeenageWitch'' Zelda looks into Sabrina's ear and can see Hilda through the other ear.

-->'''Lilly:''' (''Lifts Miley's hair and peers into her ear'') "Hey Oliver, I can see you!"
-->'''Oliver:''' (''Looks into Miley's opposite ear'') "Oh, I see you too!" (''They wave at each other.'')
* In ''Series/TheOuterLimits1995'' 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 deliquents. 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 [[BrainlessBeauty pretty ditzy]] so this might have been a stealth pun...
* In the short lived sitcom ''Series/ThePitts'' Lizzy Caplan played a ButtMonkey BrattyTeenageDaughter who 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 embarassment of being a teenage girl with a pipe through her head.) At one point a doctor shone a torch through her pipe and could see out the opposite side.
* One episode of ''TheBeverlyHillbillies'' 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.
* An episode of ''Series/{{Victorious}}'' had Cat get a butterfly stuck in her left ear. After several attempts to get it out Robbie enlists the aid of Andre's grandmother who yells into Cat's left ear, causing the butterfly to fly out the opposite ear. {{Lampshaded}} by a confused Robbie:
-->'''Robbie:''' "But it came out of your right ear."
-->'''[[TheDitz Cat]]:''' "[[ComicallyMissingThePoint It's a miracle!]]"
* Invoked in ''Series/OperationOuch'' when one of the doctors is looking in his brother's ear and claims to be able to see daylight on the other side. His brother hen tries to look for himself.

[[AC: Music Video]]
* The TomPetty 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 [[DumbBlonde blonde]] woman and play the whole song inside her ([[BrainlessBeauty mostly empty]]) head. She eventually uses a q-tip to get rid of them.

[[AC: Newspaper Comics]]
* In an early 1980s ''ComicStrip/{{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 ''ThePerishers'' 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.

[[AC: Print Media]]
* Several versions of this trope turned up over the years in the pages of ''WeeklyWorldNews'' 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").

* In ''VideoGame/{{Psychonauts}}'', Raz is able to look directly into the brain cavity through the ear, and can see right out the other ear of brain-theft victims.
