YMMV / The Simpsons S 16 E 9 Pranksta Rap

• Harsher in Hindsight: Chalmers reveals in the end that his wife is sick. As later seasons established him as a widower who lives alone with his daughter Shauna, his wife likely died from said illness.
• Memetic Mutation: The "Thursday the 20th" necklace mentioned below is a popular meme whenever the 20th of a month falls on a Thursday (usually several times a year).
• One-Scene Wonder: Towards the end of the episode, Alcatraaaz and his entourage provide video evidence of Bart attending the "Murder 4 Life" benefit concert for Skinner and Lisa. After seeing a rapper wearing a giant watch indicating the exact time Bart was at the show, Skinner laments, "If only we had the exact date." The video then shows a rapper wearing a "Thursday the 20th" necklace◊.
• Strawman Has a Point: The ending positions Lisa as a Principles Zealot who wants to expose the truth even though letting Bart's lie stand will hurt no one and help multiple people, but considering that Wiggum failed to discover the truth himself and got an innocent man jailed for kidnapping (even if he liked being in jail), he probably shouldn't have been promoted to Police Commissioner.
