In season 8's "My Sister, My Sitter," Lisa brings Bart to the ER. Everyone in line is sitting down, except for Smithers. When Lisa asks if they can cut in front of him, Smithers, while straining, explains, "I really would rather get this taken care of."
Only years later are we now finally realizing why Smithers was unable to sit down. Ah, innocence...
Sure, Lisa's reading a blatant knock-off, but hey, animation is built on plagiarism! If it weren't for someone plagiarizing The Honeymooners, we wouldn't have The Flintstones. If someone hadn't ripped off Sergeant Bilko, there'd be no Top Cat. Huckleberry Hound, Chief Wiggum, Yogi Bear? Hah! Andy Griffith, Edward G. Robinson, Art Carney.
This store was seen in the background when the family visited Chinatown. And if you are still unsure of what this joke means, might we suggest contacting Mr. Sparkle? He'll send you a premium that'll answer questions 100%.
This image was presented at the end of a clip show as a tongue-in-cheek joke about the future of The Simpsons. But please, don't take it seriously. You should have no fears, they've got stories for years. Like... Marge becomes a robot. Maybe Moe gets a cell phone. Has Bart ever owned a bear?
We knew this day would eventually come: when the running gags become self-aware. Now that they've developed intelligence, they will soon turn on us. It's only a matter of time before humanity is destroyed forever.
...Oh, wait. We just thought about another explanation: some really lazy writers.
