* PlagiarismInFiction: Roger Meyers, Sr. plagiarized Itchy from Chester J. Lampwick; and Lester and Eliza shown that the U.S. Mail's Mr. Zep 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.

* 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?
