Mayor Quimby: And now, it gives me great pleasure to present the power plant warning sign, which will be visible from the hills to the entire city. And now, a demonstration! The nuclear plant status will be presented as such.
Warning sign: [NO PROBLEM. EVERYTHING IS FINE.]
Warning sign: [MINOR FALLOUT. ROLL UP WINDOWS.]
Warning sign: [MELTDOWN. FLEE CITY.]
Warning sign: [CORE EXPLOSION. REPENT SINS.]
Audience is in stunned silence over gravity of such a warning; all except for Carl, Homer, and Lenny, who are snickering because they think that warning sign is ridiculous
Homer: Joke's on them. If the core exploded, there would not even be the power to light that sign!
Homer: Hello, my name is Mr. Burns. I believe you have a letter for me.
Postal Worker: Okay, Mr. Burns. What's your first name?
Homer: I don't know.
Outside post office sitting on steps
Homer: Gee, Bart, do you have any more bright ideas?
Homer: I'll show you mad in the morning! (chokes Bart)
Marge: Homer, you encouraged him. You should be strangling yourself!
