This is when a character gets on another character's nerves, usually by talking nonstop, and the other character covers his ears and starts singing so he can't hear him.
The person doing this will almost always either start singing The Star Spangled Banner
, or else just go "La la la". This is sometimes done (in-universe or in real life) to avoid hearing a spoiler
, something Squicky
, or anything else that a character feels he or she would be better off not hearing. Usually Too Much Information
- Done in an Australian ad for insurance, aka CUA, where many people are blocking their ears and singing 'LA LA LA LA' all for just insurance rates.
- In an episode of Happy Endings, Brad does this twice. First, when someone brings up Sexandthe City, going "lalalala, I have it on DVR!" Then later, when Max mentions that Jane (Brad's wife) slept with nearly every guy she dated, he says "lalalala, let me know when you're done!"
- Played for Laughs in an episode of True Blood: One of the main characters is a psychic, and one of her friends wanted to keep a secret from her. When the psychic tunes into her friend's thoughts, all we hear is "LALALALALALALALALALALALALALA".
- Invoked/Exploited/Enforced (whatever) in Bones where Booth has to talk to Brennan and Sweets about something grisly in front of his young son, so he has his son cover his ears and sing a song while the adults talk.
- Attempted by Kurt on Glee when his dad gives him "The Talk". Fortunately his dad forces him to sit and listen to what winds up being a very sweet discussion about the importance of self respect and sex.
- A dead serious example in Farscape where John escapes Scorpius by singing "The Star Spangled Banner" to drown out the influence of Scorpius' neural clone.
- A very funny version in Stargate SG-1 when O'Neill tries to calm down a very angry Teal'c.
O'Neill: Look, T, I'm not gonna tell you how to raise your kid, but I've always found that sticking your fingers in your ears and humming loudly solves a whole slew of problems.
- When G'Kar objects to the Centauri Emperor's upcoming visit to Babylon 5, Sheridan sarcastically tells him that if he can't deal with it he should put his fingers in his ears and hum really loud until it's over.
- When Charlene and Robbie on Dinosaurs ask a teacher questions he doesn't want to answer he goes "La la la, can't hear you!"
- In Avenue Q, Rod tries using "la la la" when Nickie tries to discuss homosexuality with him in the "If You Were Gay" number.
- There's an NPC in Ratchet & Clank: Going Commando - a biker in Vukovar Canyon on planet Barlow - that uses this trope because Ratchet offended him; he is only willing to listen to Clank.
- This happens twice in Kid Icarus: Uprising: Thanatos does it when Pit wonders aloud whether Thanatos is Obfuscating Stupidity or just dim, and Viridi does it when Pit comments on how the Komaytos look like Metroids (because, according to Viridi, the two video game universes have nothing to do with each other).
- In The Sims 2, if two sims have a bad conversation one of them might cover his or her ears and go "La La La La!".
- In Tales of Monkey Island Episode 1: Launch of the Screaming Narwhal, Guybrush does this when he is talking the Voodoo Lady. To avoid her very long talking, Guybrush plugs his ears and says, "La-la-la-la! Not listening!" This mutes the Voodoo Lady's voice before Guybrush unplugs his ears, just in time to hear the rest of the Voodoo Lady's talking.
- Similarly in The Curse of Monkey Island, if you don't want to hear Le Chuck's explanation of past events, one of the options is for Guybrush to turn his back to him, cover his ears and shout "Lalala, I can't hear you, lalalala".
- Diablo II: Blizzard warns you, they will not recover your Hardcore Character if it dies.
Blizzard will not, and does not have the capability to restore any deceased Hardcore characters. Don't even ask. La-la-la-la-la, we can't hear you...
- In Super Smash Bros. Brawl, Snake gets sick of the Colonel making fun of Luigi and calls him out on it only to get this response, doubling as a Mythology Gag:
Snake: Colonel, what's gotten into you?!
Colonel: La li lu le lo! La li lu le lo! La li lu le lo!
Snake: Colonel, snap out of it! Colonel!!! Coooooooloneeeeeel!!!
- A running gag in early Arthur, King of Time and Space was Arthur doing this every time Merlin started predicting things he didn't want to hear.
- In Freefall, one of the robots uses this as a "security measure" against sticky notes detailing Gardener in the Dark, an update which will effectively lobotomize every robot on the planet, and which is forced on any robot which searches the name on the network, because all they know about it is that it's so dangerous it caused one of them to open his power breaker to avoid its effects. 
- Understandably done in Questionable Content by Faye while Dora and her recently out of the closet younger sister feel the need to openly discuss intimate things.
- In Hiimdaisy's Let's Destroy the Shagohod, Snake gets defeated by The End and dragged a fair distance away from the boss arena. Snake gets slightly frustrated, and starts sprinting through the jungle. When a guard spots him, Snake, while still sprinting, says "La la la! I can't hear you!"
- In Leftover Soup, Jamie takes Simon's suggestion a bit literally.
