Goofs:
Errors made by characters (possibly deliberate errors by the filmmakers): At the very end of the film, Baxter and Fran sit down to play a game of Gin. This game is played with 10 cards dealt to each player, but Baxter deals at least 13 cards to both Fran and himself before the picture finally fades out. (more)

Quotes:
Fran Kubelik: I never catch colds.
C.C. Baxter: Really. I was reading some figures from the Sickness and Accident Claims Division. You know that the average New Yorker between the ages of twenty and fifty has two and a half colds a year.
Fran Kubelik: That makes me feel just terrible.
C.C. Baxter: Why?
Fran Kubelik: Well, to make the figures come out even, if I have no colds a year, some poor slob must have five colds a year.
C.C. Baxter: [sheepishly] Yeah... it's me.
