Marge: I'm not going to live in a house of evil just to save a few dollars!
Evil Spirit: Get out.
Marge: What on earth was that?
Homer: Probably just the house settling.
(Lisa finishes reading The Raven.)
Bart: Lisa, that wasn't scary, not even for a poem.
Lisa: Well, it was written in 1845. Maybe people were easier to scare back then.
Bart: Oh, yeah. Like when you look at Friday the 13th, part one. It's pretty tame by today's standards.
(Kang shows off his TV to the Simpsons.)
Kang: On this cable system, we receive over one million channels from the furthest reaches of the galaxy.
Bart: You get HBO?
Kang: No. That would cost extra.
(In the evil house, Marge catches the rest of the family trying to kill each other with knives.)
Marge: That does it. Children, get dressed. We're leaving.
Homer: Come on, Marge. You said you'd sleep on it.
Marge: I don't care what I said. This family has had its differences and we've squabbled, but we've never had knife fights before, and I blame this house.
(Lisa confronts Kang and Kodos.)
Lisa: Well, why were you trying to make us eat all the time?
Kang: Make you eat? We merely provided a sumptuous banquet. Frankly, you people made pigs of yourselves.

Bart: Are you my conscience?
Evil Spirit: I--Yes, I am.
(Homer convinces the family to stay in the "Bad Dream House.")
Homer: Now, wait a minute, Marge. It's only natural there'd be some things wrong with an old house like this. It's a fixer-upper. What's the problem? We get a bunch of priests in here--
Marge: I'm not going to live in a house of evil just to save a few dollars.
Homer: Don't be so stubborn! We're not talking about a few dollars.

(A scene from "The Raven.")
Homer: (Chuckles) Though thy crest by shorn and shaven, thou--
Narrator: I said.
Homer: --art sure no craven, ghastly, grim and ancient Raven wandering from the nightly shore--Tell me. Tell me what thy lordly name is on the night's Plutonian shore!
Narrator: Quoth the Raven.
Bart: (Interrupting) Eat my shorts!
Lisa: Bart, stop it! He says "nevermore." And that's all he'll ever say.
Bart: Okay, okay.
(In "Bad Dream House" Homer calls up his realtor after he finds out the house was built on an Indian burial ground.)
Homer: Mr. Ploot, Homer Simpson here. When you sold me this house, you forgot to mention one little thing. You didn't tell me it was built on an Indian burial ground! (Pause) No, you didn't! (Pause) Well, that's not my recollection! (Pause) Yeah? Well, all right, goodbye!
(Homer hangs up the phone and turns to his family.)
Homer: He says he mentioned it five or six times.
(Kang and Kodos show off the amenities on their spaceship.)
Kang: And over here is our crowning achievement in amusement technology: an electronic version of what you call table tennis.
(Kang shows off a video screen that features the vintage video game Pong.)
Kang: Your primitive paddles have been replaced by an electronic--
Bart: Hey, that's just Pong. Get with the times, man.

Kang: Well, we did build this spaceship, you know.
Kodos: Anyone from a species that has mastered intergalactic travel, raise your hand.

Marge: Sorry. Your game is very nice.
