First Aired - 3/17/1996
While following an ''Itchy and Scratchy'' Diamond Anniversary parade float into the bad side of town, Bart meets a homeless man who turns out to be the original creator of Itchy the Mouse back in 1919 who had his idea stolen from him by Roger Meyers, Sr.
* AnvilOnHead: Chester J. Lampwick tells Bart and Lisa the story of how Roger Meyers, Sr. dropped an anvil on him after he requested royalties for his creation. Luckily, he says, he was carrying an umbrella at the time.
* CharlieChaplinShoutOut: Chaplin is seen in the slums when Bart first meets Lampwick. A deleted scene had Homer asking Lampwick to [[EatingShoes eat a shoe]] for him, in reference to the Chaplin movie ''Film/TheGoldRush''.
* ChekhovsGun: Early on, Bart sees an animation cel for sale in the Android's Dungeon. It ends up being the damning piece of evidence needed to prove that Roger Meyers, Sr. plagiarized Itchy from Chester.
** The Android's Dungeon has some of the dolls from ''Itchy & Scratchy Land''. Later on, the Blue Haired Lawyer cites Disgruntled Goat as one of Rodger Mayers Senior's creations.
** The Itchy & Scratchy parade passes through Bumtown (from ''The Springfield Connection''). The abandoned 4-H Club from "The Boy Who Knew Too Little" can be seen as it enters.
* DeliberateValuesDissonance: The 1919 "Itchy" cartoon, where Itchy attacks an Irishman, in a parody of the older theatrical cartoons that have racist caricatures in them [[note]]Which also included the Irish, but these days, censors mostly edit the racist caricatures of blacks (both native Africans and African-Americans), Jews, American Indians, Mexicans, and Asians (mostly Chinese and Japanese stereotypes, but Indians and Arabs are often targeted as well)[[/note]]. Caricatures of Pacific Islanders, the Irish, the Scottish, the French, the British, Russians, Australians, Americans, and Italians (most of the time) aren't cause for alarm by the censors unless MediaWatchdog groups specifically say it's offensive).
* GodIsEvil: In the ''Itchy & Scratchy'' cartoon, Itchy prays to God, whom helps him killing off Scratchy and throws the cat off into the eternal pit of Hell fire. Seems very unethical for a Supreme Being. Then again, he appears to be a mouse.
* HistoricalDomainCharacter: UsefulNotes/TheodoreRoosevelt appears in ''Itchy the Lucky Mouse in Manhattan Madness'' and gets decapitated in Itchy's gruesome tirade.
* IgnorantOfTheirOwnIgnorance: Bart tells Chester he can sleep on the floor in the basement, "just remove the bed".
* MrAltDisney: Roger Meyers keeps his father's head inside a fridge, a reference to the urban legend that Creator/WaltDisney was cryogenically frozen after his death.
* MysteriousMiddleInitial: Chester J. Lampwick.
* MythologyGag: Lester and Eliza are based off the old designs for Bart and Lisa when there were on ''The Tracey Ullman Show''.
* NationalStereotypes: In reference to ethnic stereotyping in old cartoons, Itchy kills off a stereotypically clothed Irishman by sticking him between a trouser press.
* NiceJobBreakingItHero: By helping Chester attain the money he was owed for creating ''Itchy'', Bart causes Itchy and Scratchy Studios to go bankrupt and gets his favorite cartoon pulled off the air.
* NoCelebritiesWereHarmed: Except for UsefulNotes/TheodoreRoosevelt in the ''Itchy'' cartoon.
* ParodyAssistance: That was the real Jack Sheldon as the voice of the Amendment in the ''WesternAnimation/SchoolhouseRock'' parody, "I'm An Amendment to Be".
* PlagiarismInFiction: Roger Meyers, Sr. plagiarized Itchy from Chester J. Lampwick; and Lester and Eliza shown that the U.S. Mail's Mr. ZIP was a plagiarism from a character created by Roger Meyers, Sr. Ironically, Roger Meyers, Jr. points out a number of characters are based on figures from other fiction, just changed to be their own character. Even then, that doesn't let his father off the hook for stealing a character that wasn't his.
-->'''Roger Meyers, Jr.:''' Animation is built on plagiarism! If it wasn't for ''[[Series/TheHoneymooners The Honeymooners]]'', we would have never had ''WesternAnimation/TheFlintstones''! If someone hadn't made ''[[Series/ThePhilSilversShow Sergeant Bilko]]'', there'd be no ''WesternAnimation/TopCat''! WesternAnimation/HuckleberryHound, [[BreakingTheFourthWall Chief Wiggum]], WesternAnimation/YogiBear? Hah! Andy Griffith, Creator/EdwardGRobinson, Art Carney.
* RealLifeWritesThePlot: The story is inspired by the feud between Creator/PatSullivan and Creator/OttoMessmer, whom both claimed to have been the original creators of WesternAnimation/FelixTheCat.
* ReluctantGift: When Roger Meyers, Jr. presents the check, he refuses to let go for a few seconds and Lampwick struggles with him. When Lampwick finally wrests the check away, [[TastyGold he bites it as if testing for a counterfeit coin]].
** How did Bart and Lisa expect to save the cartoon company? Was it the same way Lester and Eliza did?
** When did Apu get busted for indecent exposure? And what about Krusty and his estranged wife?
* RunningGag: Someone offers Chester food for a job, which he never does and complains the food was awful. Then they demand him to do the job he's hired to do, Chester says "Make me!", and a fight ensues.
** The title "The Day the Violence Died" is a reference to [[https://en.wikipedia.org/wiki/The_Day_the_Music_Died "The Day the Music Died"]], the nickname for the February 3, 1959 event when rock 'n' roll stars Music/BuddyHolly, Music/RitchieValens and Music/TheBigBopper all died in a plane crash. The nickname was thought up by Music/DonMcLean in his song "Music/AmericanPie".
** ''Itchy & Scratchy Meet Fritz the Cat'' is a reference to ''WesternAnimation/FritzTheCat''.
** The very first ''Itchy'' cartoon is a stylistic parody of silent animated cartoons like ''WesternAnimation/FelixTheCat'' and ''WesternAnimation/GertieTheDinosaur''.
** Bart and Lisa watch a rerun of ''WesternAnimation/SchoolhouseRock'' on TV.
** The final ''Itchy & Scratchy'' cartoon where Itchy chases Scratchy in a desert landscape over a road brings ''WesternAnimation/WileECoyoteAndTheRoadRunner'' to mind.
* SpecialGuest: Creator/KirkDouglas voices Chester Lampwick.
* StrangeMindsThinkAlike: Grampa Simpson and Krusty the Clown. Both of them offered Chester food as payment for chores he refuses to perform because the food was awful and fight Chester when he dares them to make him do the chores.
* TheUnreveal: We'll never know what plan Bart and Lisa concocted to help save Itchy and Scratchy Studios, since two lookalikes beat them to it.
* WritingAroundTrademarks: The "Schoolhouse Rock" parody is never identified as such, but it looks and feels like one.
