Chalkboard: Ralph won't "morph" if you squeeze him hard enough
Couch: Repeat of the circus/showbiz extravaganza couch gag from "Lisa's First Word".
Bart: Cheer up, Homer.
Marge: What if you pretended that this couch were a bar? Then you could spend more nights at home with us. Huh?
Homer: I'm not going to dignify that with an answer.
Lisa: Look on the bright side, Dad. Did you know that the Chinese use the same word for "crisis" as they do for "opportunity"?
Homer: Yes! Cris-atunity.
Airport Official: If word gets out about this then Krazy Klown airlines will be a laughing stock. In return for your silence, I'm prepared to offer your family free tickets to anywhere in the United States, excluding Alaska and Hawaii, the freak states.
Homer: Woo Hoo!
Homer: Good news, everybody! Because I endangered lives, we can fly anywhere we want!
Lisa: Mom, you've been cooking all night?
Marge: (happy) Judge, jury, and executioner, all rolled into one, you are!
Lisa: See, Dad? I told you Mom would have problems.
Marge: No, no, honey, it's all right. Really, I'm fine, I'm all right. (to self) Mother always said, 'Don't complain. Be good. Behave. Behave. Be nice. Smile. Be polite. Don't wink, don't make waves. (walks out)
Homer: You heard your mother's ramblings. She's fine, so behave.
In this episode, it's established that Margie is aviophobic (has a fear of flying), but in season three's "Mr. Lisa Goes to Washington", the Simpsons flew on a plane to Washington, DC and Marge didn't freak out like she did in this episode.
