Funny / After the Thin Man

• Nick and Nora arriving home after a long train ride, intending to sleep right through New Year's Eve, only to walk in on a "Welcome Home" party for them that had grown so out of hand that most of the guests don't even seem to know who Nick and Nora are.
• Nick becoming a one-man snark parade while stuck in a room with Nora's elderly male relatives, who have all fallen asleep, talking to them as though they're having a discussion-turned-argument whenever one of them snores.
• This exchange:
  Nick Charles: You see, when it comes to words like that, an illiterate person...
  Polly Byrnes: Whaddaya mean "illiterate"!? My father and mother were married right here in the city hall!
• When Nick finds yet-another-body:
  Nick: What is this, bank night?
• Quack Doctor Kammer's stunned comment after the murderer is dragged away raving: "My god. I was right. He really was crazy."
• The "walk this way" gag:
  Nick: Well, I'll try. (imitates the shambling old butler).
• Nora is found in an embarrassing situation and tossed in the drunk tank with a bunch of other women until Nick comes to pick her up.
  Police Secretary: Is this the one who was doing the fan dance?
  Nick: If she is, she's been holding out on me.
• Nick winding up playing peek-a-boo with Asta around the end of a couch after Asta runs off with a clue tied to a rock.
• After dropping a series of increasingly unsubtle hints throughout the movie, Nora drops all pretense at the end and outright presents Nick with the pair of baby socks she's been knitting. As the look of dawning realization spreads across Nick's face, she smiles and quips:
  Nora: And you call yourself a detective.
