Stock Audio Clip

Sometimes in cartoons, a character may say the same line over and over, with the same recording of the same line. There is a variation in which two characters may get into an argument (Duck Season! Rabbit Season!) and use the same sound clip. A subtrope of Catch Phrase and Stock Sound Effect, and an audio variation on Stock Footage. Also common in video games, where it usually becomes the Most Annoying Sound.

Film

 * A Hong Kong martial-arts movie titled Hapkido, in its original English dub, referred to the titular martial art as "kung fu". It was later redubbed to correct this-- but rather than redubbing the dialogue completely, the dubbers just pasted the word "hapkido" over "kung fu". It's frequently the same recording of the word-- even when several different characters are saying it. It must be seen to be believed.

Live Action TV

 * In the Doctor Who serial The Chase during the Daleks' fight with the Mechanoids all the lines spoken by the Daleks were from earlier in the serial (in fact mostly from their first scene in the first episode).
 * Inverted in a Monty Python's Flying Circus sketch, where a vox pop interviewee (Eric Idle) is stuck in a rut (stuck in a rut, stuck in a rut). Instead of replaying the same dialogue over and over, Idle just repeats the phrase.

Western Animation

 * Courage the Cowardly Dog: Muriel: Two recordings of "Oh my!"; Eustace: "Stupid dog!", "BOOGA BOOGA BOOGA!", various grumbles; Courage: "The things I do for love!", "Muriel, I'll save you!", babbling; All characters: screaming. Dr. Vindaloo: What is up with that?
 * With the titular character, it's quite possible that the voice actor did a -single recording session- and never stepped into the studio again. "Oh no!", his whining noise, his scream, the oddly low-pitched laugh, all sound the same each time you hear them. In fact it's more likely you will be surprised by hearing a -less often- used sound clip for Courage.
 * Ed, Edd n Eddy: Ed: Gravy! Rolf: You crazy!, laughing Nazz: This is stupid. Kevin: Dorks! Jimmy: And it was such a cute squirrel, too. Ouch! Wah-ha-ha-haaaa (that whiny crying he does from time to time, such as getting hoodwinked by Eddy with "Smilyland" or after getting maimed by his own eyelash curler).
 * The Roadrunner's "Meep Meep".
 * The practice is parodied in The Simpsons in the episode "The Itchy & Scratchy & Poochie Show", when one of the people working on the Itchy & Scratchy show claims that not only did Warners reuse a single "Meep Meep", they actually had the voice artist say "Meep" once and then doubled it up.
 * Futurama uses the exact same scream every time Amy falls over.
 * The episode "Brannigan, Begin Again" used a recording of the judge calmly saying "I'm going to allow this" several times, in increasingly odd circumstances.
 * Phineas and Ferb: Candace: several different screams, "Meep...". Perry: chattering. Isabella: "Whatcha doin'?". Bob Weber: "OK!"
 * Spongebob SquarePants frequently has an off-screen guy shout "My leg!," usually as the series equivalent of That Poor Cat.
 * Don't forget Spongebob's signature laugh.
 * Disney has the Goofy Holler. ("Waah-hoo-hoo-hooey!") Used mostly on the Goofy shorts (natch), but pops up on the animated features, theme parks, and even the live-action films.
 * Much of Tom's screams and yelps are recycled throughout the many shorts he has appeared in.
 * In an episode of American Dad, Stan accidentally discovers the joys of A Date With Rosie Palms while trying to treat an injury to his groin. The same ludicrously over-the-top scream is recycled every time he orgasms.
 * Lampshaded in the latter-day Bugs Bunny cartoon Invasion of the Bunny Snatchers, where the badly drawn and animated alien dopplegangers of Daffy, Elmer and Sam constantly repeat (respectively) "You're despicable," "I'm hunting wabbits" and "Rackafrackin' varmint" ad nauseum. Bugs, collecting the lookalikes to get rid of them, calls them "broken records."

Other

 * The Wilhelm scream. Look it up; you've Heard It A Million Times.
 * There's stock background radio noise, including one that sounds like "Seventy-Eight Straight Track Cupcake".
 * That outrageously overused sound of a cat screeching: Mrrr-EEOOOWWW!! Sometimes, not just the one screech, but several from that one stock audio track!! Give it a rest already, Hollywood!!
