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.
Adaptation Displacement: The Disney Channel replaced the Benny Goodman score to "All the Cats Join In" with a different song, "Rock Around the Clock" by Bill Haley, for its "DTV" interstitials in The Eighties. To this day, some people think "Rock Around the Clock" was there first, despite having come out 10 years later.
Memetic Mutation: /co/ occasionally has Willie the Whale images being posted in response to inflation/fat threads.
Nightmare Fuel: The wolf's appearance at the beginning of 'Peter and the Wolf."
Viewer Gender Confusion: While they are both referred to as hes, Sasha the woodpecker and Sonia the Duck could easily be mistaken for females, if just for their names. (To Westerners, at least; Sasha is a common male name in much of Europe, including Russia, where the story is set.)
