"Blitzkrieg Bop" by The Ramones (Used while Milhouse, Nelson, Bart and Lisa go on their prank rampage.)
Lisa: I can't believe that an alien who looked so evil turned out to be bad.
Marge: Hmm, I guess you should judge a book by its cover.
Secret Agent: Definitely! Especially if you count the inside flap as part of the cover, it usually gives you a great idea of what the book's about.
(From "Mr. & Mrs. Simpson.")
Marge: All those nights I thought you were out getting drunk, you were out killing people?!
Homer: I was out getting drunk, then killing people!
Ned Flanders: That concludes our Halloween show for this year. I just wanna say that for those watching this network, you're all going to Hell and that includes FX, Fox Sports, and our newest devil's portal, The Wall Street Journal. Welcome to the club!
(In "Mr. & Mrs. Simpson" Homer is talking to Mr. Burns via satellite.)
Mr. Burns: Greetings, 241.

(In "Mr. & Mrs. Simpson" Homer and Marge both shoot Principal Skinner.)
Principal Skinner: (Dying) Remember me... on pizza... Fridays.
(In "E.T. Go Home" Bart shows Kodos his bedroom.)
Bart: So, this is my Krusty doll, Funzo, Linguo, Iraq War Sergeant Activity with insufficient armor, Phonic Frog, cat skull, Jim Halterman bobble head doll. He's a local car dealer.
(Kodos grabs the bobble head doll.)
Kodos: Hmm. Do all humans have such weak necks, or just the one you call "Jim Halterman"?
(In "Mr. & Mrs. Simpson" Homer prepares to assassinate Kent Brockman using a sniper rifle.)
Homer: Now all I have to do is think of a clever line before I pull the trigger. (Thinks) Oh, that's a perfect one. But I don't need to say it out loud 'cause I'm by myself.
(In "Mr. & Mrs. Simpson" Marge serves Homer dinner.)
Marge: Homie, I made you my killer lasagna.
Homer's Brain: It's poison. Whatever you do, don't eat it.
(Homer takes a bite.)
Homer's Brain: Okay, you're already eating it, but don't finish it.
(Homer finishes the lasagna.)
Homer's Brain: Okay, you finished it, but don't ask for--
Homer: Seconds, please.
Homer's Brain: You moron! Just kill her!

Chief Wiggum: I would have taken a bribe. (Collapses on the floor.)
(In "Heck House" Bart dispenses a little "wisdom".)
Bart: "Trick or Treat" isn't just some phrase you chant mindlessly like The Lord's Prayer. It's an oral contract!
(In "Mr. & Mrs. Simpson" Marge pulls a bloody machete out of the dishwasher.)
Marge: Hmm. You just can't get Russian gangster blood out. Must be something they eat.
