* AlternateAesopInterpretation:
** The story was an allegory for Fascism but many perceived it as one for [[GoodGirlsAvoidAbortion abortion]].
** It works as an allegory for Isolationist foreign policy too.
* SequelDisplacement: This one is much better known in the mainstream than ''Literature/HortonHatchesTheEgg'' and especially ''[[Literature/HortonAndTheKwuggerbugAndMoreLostStories Horton and the Kwuggerbug]]''. In fact, there are some who are aware of the other stories that think they're a sequel to ''Hears a Who!'' instead of the other way around (especially since ''Kwuggerbug'' only got an official book release in 2014).
