There’s a scene in Stanley Kubrick’s comic masterpiece Dr. Strangelove in which Jack D. Ripper, an American general who’s gone rogue and ordered a nuclear attack on the Soviet Union, unspools his paranoid worldview—and the explanation for why he drinks “only distilled water, or rainwater, and only pure grain alcohol”—to Lionel Mandrake, a dizzy-with-anxiety group captain in the Royal Air Force.
Ripper: Have you ever heard of a thing called fluoridation? Fluoridation of water?
Mandrake: Ah, yes, I have heard of that, Jack. Yes, yes.
