Yes, the whole story's told in a sidebar.

This was an attempt by the government to kill off those of us aware of the true nature of things! Think about it!

Tinfoil - Free, cheap, non-toxic (Unless you eat it to absorb its properties.. but those people are just crazy).

What's the alternative? Why LEAD of course! It blocks everything! But simply wearing it on our heads..That can be lethal! The lead will permeate the skin on our skulls and give us lead poisoning directly in our brains! And it ain't cheap either! How can I continue to afford to stock up on freeze-dried astronaut food??! And don't even get me going about how heavy it is.. My head could snap clear off my spine because of the weight!

Damn you, government sponsored scientists! You've FOILED our plans again!
