YMMV / Animal Crackers

• Adaptation Displacement: The film is much more well known than the stage play, which is impossible to revive without the Marx Brothers (though it has occasionally been mounted with actors imitating them).
• Hilarious in Hindsight: Chico and Harpo recognize one of the high-society partygoers as a former fishmonger named Abie, and Chico taunts him by chanting "Abie the Fish-man" in mocking singsong. Decades later, we'd be introduced to another "fish-man" named Abe.
• Parody Displacement: Eugene Oneill's Strange Interlude, which featured characters stepping out of the action and verbalizing their inner monologues, was popular enough at the time that both the stage and screen versions of Animal Crackers featured a parody of it, but most people hear about it for the first time when Groucho says "pardon me while I have a strange interlude".
• Signature Scene: Groucho's comment about "shooting an elephant in his pajamas".
