When Disney's Little Mermaid came out, my dad got very grumpy after listening to "where the people are" because all he heard was "I want more..." and assumed it was a plug for crass commercialism and continually getting more Stuff. He wouldn't listen when I pointed out it was the exact opposite -- that she's saying the stuff isn't important, what she wants is experiences.

I kinda assume the same is true for the people who think "Puff" is about drugs. They hear "puff" (clearly a drug reference) and "magic dragon" (obviously a hallucinogenic drug", and don't even listen to the rest.
