Inside the Karma-Ceuticals store is a banner with the stonecutters emblem on it.
The new age store Homer and Lisa visit is named "Karma-Ceuticals".
The brand of baby monitor Marge uses is "La-Z-Mom".
In the scene after Lisa becomes Bart's roommate- Maggie hold in her hand one of the characters of Matt Groening's "Life in Hell" comic- named Bongo- he is a one eared rabbit.
After Homer has licked the writing off the Bill of Rights, he shows that he still has the letters on his tongue. The words 'cruel and unusual' can be seen, but they're forwards. They should be backwards since he licked them off.
The 15-star flag should have 15 stripes, not 13.
The Bill of Rights and the Constitution are at the National Archives, not the Smithsonian.
The Liberty Bell isn't on display at the Smithsonian. Instead, you can see it near Independence Hall in Philadelphia, PA.
Hippie Lady: But the I Ching said I had six months till bankruptcy.
Repo Man: Hey, channel somebody who gives a damn!
(Marge is listening in)
Moe: Lenny, how are you doing? This is Moe. I've got some class three gossip here.
Lenny: Well, dish!
Moe: Groundskeeper Willie … you know, the guy in the skirt bought himself a mail-order bride. But he's too cheap to pay the C. O. D., right? So she's still in a crate down at the post office. Wanna go look-see?
Marge: Ooh, this sounds juicy.
Hibbert: Lisa, I'm afraid your tummy ache may be caused by stress.
Homer: Well, that's a relief.
Hibbert: Heh, yeah. Anyway, when it comes to stress, I believe laughter is the best medicine. You know, before I learned to chuckle mindlessly, I was headed for an early grave myself.
Homer: Give it a try, honey.
(Lisa tries to chuckle)
Hibbert: Oh, now you call that chuckling? Come on, child, force it.
Lisa: I'm really not the chuckling type.
Homer: It's true. I'm always making clever noises, and she never chuckles at 'em.
Homer: (turns on TV) Ooh, here's something you like. When Animals Attack Magicians.
Magician: Pick a card, any… (noise of animal attacking) Aaaaaagh!!!
Lisa: That's awful.
Homer: Awful entertaining.
Agnes: Seymour? You were supposed to call me three minutes ago.
Skinner: Sorry, mother, I was driving through a tunnel and my cell phone wouldn't work.
Agnes: I don't want you driving through tunnels. You know what that symbolizes.
Skinner: But Mother, it cuts ninety minutes off my drive.
Agnes: No tunnels!
Marge: It's just until we pay off Daddy's desecration of a priceless artifact. I thought I'd never have to say that again.
Lisa: I can't believe you did this, Dad. Why didn't you put that thing in your room?
Homer: Hmmm. That thought never occurred to me. Funny how your mind works in a crisis.
Homer: What? I heard a yell. Did you touch a wire?
Lisa: What happened to my room?
Homer: Nothing. They just needed a place to put all the electronic gizmos, and I know how much you like that sciencey stuff. So I…
Lisa: You gave away my room!?
Homer: Come on, Lisa, try and see this from the OmniTouch corporation's point of view.
(Homer is sleeping at the power plant with the radio on)
Radio Announcer: FDR is in the White House. An ice cream cone costs a nickel, and a hot new tune by Benny Goodman is hitting the charts. The year is 1939.
Homer: Nineteen … 1939! Oh, my God, I've gone back in time! I've got to warn everybody about Hitler …and get to the ice cream store!
Lenny: Hey, Homer, what's all the hubbub?
Carl: Let me guess. You travel back in time again?
Homer: Shut up. You haven't even been born yet.
Homer: Ooh! Ee! Ooh-ah-ah! Ching, chang, walla-
walla-bing-bang! Ooh! Ee! Ooh-ah-ah!
Homer: Lisa, what's your favorite movie?
Lisa: Until you taped over it, 'The Little Mermaid'.
Homer: (Not evidently listening) That's right! The Odd Couple! So meet your comically mismatched roommate, Bart Simpson! Doo doo doo doo doo doo doo doo, doo doo doo, doo doo doo. Doo doo doo doo doo doo, doo doo doo, doo doo doo. Aahh-doo doo doo doo… (etc, to the tune of the 'Odd Couple Theme')
Security guard: You just licked off the part for cruel and unusual punishment.
(guards beat Homer up)
(The Flanders family nearly drives into Homer's sensory deprivation tank)
Maude: Oh, Neddy, you almost hit that coffin!
(They get out of their car and walk up to the tank.)
Ned: (gasps) Leaping Lazarus! Is this what passes for eternal rest these days? Rod, go get Daddy his burial shovel!
(The tank is duly buried)
Todd: You sure buried him deep, Daddy!
Ned: (laughs) Not so deep the Lord can't find him... and judge him!
Rod: This is the best birthday I ever had!
Homer: Oh, good, I've been meaning to catch a… dream catcher? Give me a break.
Lisa: I just wish you could keep an open mind about other cultures.
Homer: Other cultures are fine. I'm just saying I can get along in life without a tooth… brush.
Marge: Peoples' privacy is at stake.
Homer: Great, I'm gonna eat mayonnaise.
Homer: Who's Fonzie? Don't they teach you anything in school?
Homer: What's keeping Joan Rivers alive?
Woman: Fetal grindings.
Blackboard Joke: I do not have diplomatic immunity.
Couch Gag: Two firemen are holding the couch and adjusting it back and forth to catch Marge, Bart, Lisa, and Maggie as they fall from the sky; then Homer falls through the floor.
Life in Hell
Maggie is playing with a stuffed animal that looks like Binky from Matt Groening's comic strip, Life in Hell.
Make Room for Daddy
The episode title parodies the title of the Danny Thomas sitcom Make Room for Daddy.
