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.
YMMV: Puff The Magic Dragon
Death of the Author: Stoners won't relinquish their reading of Puff as a metaphor for weed, in spite of the author's insistence that no such metaphor was intended.
Ear Worm: The original song. Other songs introduced in the films qualify as well.
