Chalkboard: None

During the alien segment Marge's necklace is white for a brief moment.

Marge: Hello everyone. You know, Halloween is a very strange holiday. Personally, I don't understand it. Kids worshipping ghosts, pretending to be devils...things on TV that are completely inappropiate for younger viewers. Things like the following half-hour. Nothing seems to bother my kids, but tonight's show-which I totally wash my hands of-is really scary. So, if you have sensative children, mabye you should tuck them into bed early tonight instead of writing us angry letters tomorrow. Thanks for your attention.

Evil House: You will die, you will die slowly. Your stomach will swell, your intestines will writhe and boil, your eyes will burst; and some horrible stuff, possible your brains, will start coming out through your nose.

Bart the Raven: Eat my shorts!

Homer: Come here, you little raven!

Bart: Wait a minute! That's a schoolbook!
Lisa: Don't worry, Bart, you wont learn anything.

Homer: Listen, you big, stupid space-creature. Nobody, but nobody, eats the Simpsons!

(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Kang: Your primitive paddles have been replaced by an electronic--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.
Homer: Marge and I played that old game before we were married.
Kang: Well, we did build this spaceship, you know.
Kodos: Anyone from a species that has mastered intergalactic travel, raise your hand.
(Kang and Kodos each raise a tentacle. Bart raises his hand, but Homer slaps it down.)
Kodos: All right, then.
Marge: Sorry. Your game is very nice.

(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.
(Homer slowly begins floating to the ceiling.)
Homer: We're talking about a few thousand dollars!
(Homer realizes that he is floating upwards and begins screaming.)
Homer: It’s got great high ceilings!
(Homer screams as he suddenly plunges back to the floor.)
Homer: Tell you what. Let’s, uh, sleep on it, okay?

In "Hungry Are the Damned," when the family is gazing up at the UFO and Homer says the burgers are getting cold, the burger he is eating has a bite out of it. However, in a close-up shot, it is a whole burger again.

In "Hungry Are The Damned," at the very end, the family sees Kang and Kodos' ship and Marge's necklace is white like Lisa's, when it really should be red.

Poltergeist

The house in the "Bad Dream House" segment vanishes in a fashion similar to the house from the 1982 movie Poltergeist.

Psycho

The house in "Bad Dream House," looks just like the house that Norman Bates lived in the 1960 classic film Psycho.

The Exorcist

The scene where Maggie's head turns completely around without stopping is a take on the 1973 classic horror film The Exorcist.
