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.

!!!Tropes (YMMV tropes can be found [[YMMV/TheSimpsonsS7E18TheDayTheViolenceDied here]]):

* AnvilOnHead: Chester J. Lampwick tells Bart and Lisa the story of how Roger Myers, 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.
* GenreSavvy: When Snowball the cat hears that Chester Lampwick is an animator she quickly runs away in panic...
* 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.
* HeyItsThatVoice: Creator/KirkDouglas voices Chester Lampwick.
* HistoricalDomainCharacter: 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."
* LostForever: The only copy of the first Itchy cartoon is destroyed when the film catches fire and burns up.
* MrAltDisney: Roger Myers 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.
* NoCelebritiesWereHarmed: Except for Teddy Roosevelt in the Itchy cartoon.
* ParodyAssistance and HeyItsThatVoice: That was the real Jack Sheldon as the voice of the Amendment in the ''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. Cause that doesn't let his father off the hook for stealing a character that wasn't his.
-->'''Roger Myers, Jr.:''' TV 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''! Huckleberry Hound, [[BreakingTheFourthWall Chief Wiggum]], WesternAnimation/YogiBear? Hah! Andy Griffith, Edward G. Robinson, Art Carney.
* RealLifeWritesThePlot: The story is inspired by the feud between Pat Sullivan and Otto Messmer, 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]].
* RiddleForTheAges: 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.
* ShoutOut:
** "The Day the Violence Died" is a reference to "The Day The Music Died", the official nickname for February 2, 1959, when rock 'n' roll stars Music/BuddyHolly, Ritchie Valens and the Big Bopper all died in a plane crash. The nickname was thought up by Music/DonMcLean in his song [[Music/AmericanPie "American Pie"]].
** "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/WileECoyoteAndRoadRunner'' to mind.
* TimeMarchesOn: Nowadays the idea that Chester Lampwick had created Itchy way back in 1919 and is still alive to this day seems even less likely than it did in 1995.
* WritingAroundTrademarks: The "Schoolhouse Rock" parody is never identified as such.
