Chalkboard: I do not have diplomatic immunity
Couch: Repeat of the couch gag from "Bart the Mother" where two firemen save Marge, Bart, Lisa, and Maggie from falling by using the couch as a safety net--and end up missing Homer as he falls through the floor.
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: 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’)
(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.
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!
