* In an episode of ''WesternAnimation/UncleGrandpa'' named [[ItMakesSenseInContext ''Uncle Grandpa Ate My Homework'']], Dennis gets an A+++++-+!
* The plot of ''WesternAnimation/AvatarTheLastAirbender'' revolves around this. Fire Lord Ozai is the most powerful firebender in the world. But on the day of Sozin's Comet, every firebender will be much stronger than usual, which allows him to burn the world! He forgot that the Avatar was ''also'' a firebender, among other things.
* In an episode of ''WesternAnimation/ReBoot'', Megabyte gatecrashes a concert and produces a powerful electric guitar. Unsatisfied with the sound after a couple tests, he reaches for the dial and cranks it up to 11.
** At this point Bob jumps up on stage, whips out his own guitar, and the two of them have [[http://www.youtube.com/watch?v=al6ssH4vkdY an epic rock-off]]. Megabyte then says "I've always wanted to do that", gives Enzo the guitar as a birthday present, and drives off in his stretch limo.
* In ''WesternAnimation/ThePowerpuffGirls''' episode 'Bubblevicious', Bubbles got sick of being the "kid" in the group, so she turned the training simulator up to eleven to prove she was "hardcore". The result is a [[Awesome/ThePowerpuffGirls Crowning Moment of Awesome]] for her, and her sisters acknowledge it.
--> '''Buttercup:''' Wow, [[{{Badass}} she took the laser]] [[ShoutOut all the way]] up to 11!
* In the opening sequence of ''WesternAnimation/BumpInTheNight,'' Mr. Bumpy actually uses a crayon to add an 11 setting to his amp before jacking it all the way up.
* In ''WesternAnimation/TheSimpsons'', Pete Townshend (Guitarist for Music/TheWho) has an amp with a setting in place of 11 reading simply "Whuh-Oh", that's strong enough to partly demolish a wall made of solid garbage.
** Mr. Burns hires a hypnotist to motivate his softball team.
--->'''Hypnotist''': You are all very good players.
--->'''Team''': We are all very good players.
--->'''Hypnotist''': You will beat Shelbyville.
--->'''Team''': We will beat Shelbyville.
--->'''Hypnotist''': You will give 110 percent.
--->'''Team''': That's impossible. No one can give more than 100 percent. By definition, that is the most anyone can give.
* In the ''WesternAnimation/VeggieTales'' video "The Star of Christmas," [[GadgeteerGenius Seymour (Pa Grape)]] sends Bob and Larry's characters to the church where a Christmas pageant is going to be held in a rocket car. He warns them that although the car has 11 engines, they should only fire engines 1 through 10, and that [[DangerousForbiddenTechnique under no circumstances should they fire the untested rocket 11.]] Larry does anyway when the car shows that the church is out of the range of 1-10.
* In the "S'Winter" episode of ''WesternAnimation/PhineasAndFerb'', Doofenshmirtz builds a laser that has a melting capacity of seven...on a scale of one to five.
** Much of the show is the titular brothers taking everything Up To Eleven.
--> '''Phineas:''' Guaranteed to kick any party up to an eleven!
* In ''WesternAnimation/HomeMovies'', Duane's band SCAB scrawled the number 11 on the far end of their amps' volume dials.
* In the ''WesternAnimation/TeenTitans'' episode "Only Human", Cyborg is able to exceed the limitations built into his cybernetics in order to defeat Atlas. (The fact that Cyborg's human mind and willpower - not his robotic body - is the stronger part of him is later a big plot element in the third season.)
** Cyborg complains that, as a machine, he cannot go beyond 100% of his ability. He eventually goes up to 130% before the power readout breaks, and he decides not to replace it.
** A literal example occurs in "The Lost Episode", where music-using villain Punk Rocket cranks his guitar up to eleven for more power.
* In the episode "Out of This World" of ''WesternAnimation/RubyGloom'', Frank and Len crank the volume of their music up to eleven curiously at Poe's suggestion. Cue fireworks and an explosion that sends them all into orbit around the moon.
* ''WesternAnimation/MegasXLR'' is build around this trope. The guns, the robot, even the karaoke get turned to eleven regularly. Its stereo system goes [[ExaggeratedTrope up to eleven]] [[OverNineThousand thousand]].
** Said stereo actually has more security preventing its use than ''all of Megas' weapons'' and is the one weapon Coup actually considers cruel to use. As if that didn't already show how powerful it is, when combined with Coup's off-key voice, it becomes a weapon of mass destruction capable of destroying a massive space station and an army of monsters and robots in seconds.
* In ''WesternAnimation/ShaunTheSheep'', whilst trying to cure one of the other sheep of hiccups, Shaun pulls out an electric guitar and amplifier and turns the amplifier up to eleven. As soon as he plays a single chord, a mushroom cloud is seen rising out of the field.
* One episode of ''WesternAnimation/ChalkZone'' takes it one step further by cranking it up to 12 in a song at the end. It's part of the lyrics, even.

* In ''WesternAnimation/EdEddNEddy'', when Eddy and Ed take control of the school newspaper they pull the speed control lever on the printing press beyond its maximum setting, tearing through the outside of the press in the process, and write "Stupid fast!" near the new setting.
* In ''CodenameKidsNextDoor'', a cold Numbuh 3 was looking for a heater inside an ice cream factory and immediately turns it to it's maximum capacity: "Like, eleventy billion degrees". The Delightful Children From Down the Lane angrily ask [[LampshadeHanging who had the idea of putting a heater inside an ice cream factory]].
* In ''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius'', Jimmy's jetpack has a setting called, "ARE YOU NUTS!?". It's very good at cancelling out the rotation of a ''super tornado that extends beyond the Earth itself''.
* In ''WesternAnimation/WanderOverYonder'', episode "The Party Animal", when Emperor Awesome cranked the volume of his planet-ending party all the way up to 11.
