Rob is blowing a whistle, over and over.

Bob: “Why are you blowing that whistle, Rob?”

Rob: “To keep the dragons away.”

Bob: “I see no dragons.”

Rob: “It works!”

    okay but people don’t actually wear those. It’s just a joke.

    Let’s look at “tin foil hats” a bit closer: although several carefully-arranged layers of tin foil can indeed serve as a Faraday cage, wearing that as a hat would be insufficient to perfectly block RF/EMF signals because a person would need to cover their whole face and neck and shoulders and body, wrap their whole entire body in tin foil, because if there’s any opening that can access through to the brain, which would be through the neck, the Faraday cage would be ineffective.

    So yeah, people don’t really wear those hats.

      So you’re saying it’s just as effective as a whistle that “keeps away dragons”? i.e. It’s an adequate deterrent for the bullshit it “prevents”?
