* [[SugarWiki/FunnyMoments Crowning Moment of Funny]]: "I just went ''GAY'' all of a sudden!"
** Also worth mentioning: "Ohhh, you've torn your coat."
** Susan imitating a speaking clock over the phone to annoy David as he talks to his fiance. A house guest arrives, checks his watch, and corrects her as she's doing it.
** When David discovers the dinosaur bone is missing and immediately asks Susan what she did with it:
-->'''Susan:''' "What would I do with a bone?"
-->'''David:''' "I wouldn't dare give a reason for anything you would do!"
** At the very end, when David finally collapses under the strain, Susan catches him and comments with mild interest: "David, you fainted."
* EsotericHappyEnding: David loses his fiance (though they weren't marrying for love anyway), and his dinosaur skeleton (whether it's irreparable is unclear). However, he gets Susan, who he is at least very fond of at this point, and his museum does get the funding it requires.
* VindicatedByHistory: The film was a flop in its first release, to the point where Katharine Hepburn had to buy out her contract to RKO and Howard Hawks was fired from ''Film/GungaDin''. Nowadays, it's regarded as a classic.
