These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Crazy Awesome: The circus and zoo featured in If I Ran The Circus and If I Ran The Zoo.
Heartwarming Moment: The Lorax originally had the fish, chased out of their lake by pollution, say that "I hear things are just as bad up in Lake Erie". But "People indeed cared a whole awful lot,/ And worked very hard, and better it got." (to paraphrase the book's ending) - and so Dr. Seuss removed the line.
The ending of Horton Hatches The Egg: "And it should be, it should be, it should be like that / because Horton was faithful. / He sat and he sat. He meant what he said / and he said what he meant / and they sent him home, happy one hundred percent."
Misaimed Fandom: Horton Hears a Who has been co-opted as support by many pro-life groups, who use the famous line: "A person's a person, no matter how small" as their rallying cry. In truth, Seuss was commenting on how America was basically ignoring the rebuilding needs of post-WWII Japan, and that line in particular was intended to send the message that regardless of the fact that we had just fought a war against them, treating them that way was simply not right, and would probably engender further resentment against the United States.
The man himself wasn't pro-life and sued a pro-life organization for using the phrase on their stationary.
At least one right-winger has compared liberals to the mooching animals in Thidwick the Big-Hearted Moose, which invokes Death of the Author in light of Seuss' progressive political beliefs.
