YMMV / The Simpsons S2 E21 "Three Men and a Comic Book"

• Accidental Aesop: Always negotiate payment for services rendered before engaging in said services. Such a lesson would have saved Bart a week of pointless torment.
• Harsher in Hindsight: The joke about The Cosby Show being taken off the air has become this, since the show's legacy is more or less tarnished, due to Bill Cosby being accused of and briefly imprisoned for drugging and sexually assaulting female celebrities, leading to most TV channels refusing to air reruns of that show anymore.
• Hilarious in Hindsight: Homer and Bart discuss how The Cosby Show was being taken off the air to keep it from becoming stale, and joke about how they would "run that sucker into the ground" if they were in Cosby's position. More than 30 seasons later, The Simpsons is still on the air, and, for some people (and certainly the majority of fans), the show itself has been run into the ground.
• Memetic Mutation: "Kids, could you lighten up a little?"^note Responding to grim/dark posts with this screenshot has become popular, especially on Tumblr, which is home to a lot of grim and dark posts.
