On a semi-related note: I was watching some movie or TV show recently, and there's a scene that goes approximately like this:

Character A: "something, something, something, Doors of Perception."

Character B: "Okay, Timothy Leary."

Character A: "Huxley."

Character B: "What?"

Character A: "Huxley wrote The Doors of Perception, not Timothy Leary."

The thing is, I can't remember now what that was from and it's bugging the shit out of me. Any chance anybody here is familiar with the work in question and could tell me what it was?
