Okay. I'm not even going to pretend to be doing serious work. It's late in the afternoon right before a three-day weekend. Time for some serious unseriousness.
For those of you deeply worried about the radio signals that might come through your dental fillings, as a public service, we bring you the AFDB (Aluminum Foil Detector Beanie) site. The site managers have put in a lot of time and effort here. History, instructions for building your own, academic papers, a blog, and mind control news.
Also, reasons not to trust commercial versions (are there such things?) To wit, "Since you should trust no one, always construct your AFDB yourself to avoid the risk of subversion and mental enslavement. Sometimes, AFDBs will be sold on places like eBay. Do not purchase these pre-made AFDBs, even if the seller seems trustworthy. They may contain backdoors, pinholes, integrated psychotronic circuitry or other methods that actually promote mind control." Who knew?
Personally, I think the site is run from a secret location somewhere on the grounds of the Reynolds Wrap factory. Enter this site carefully, BTW. It's full of mind-control items that will immediately cause you to be hungry and/or run to the grocery store to buy a big ham and, of course, Reynolds Wrap, Then you'll have to invite people over and cook the ham, because it's Easter, after all.
Speaking of Easter, this site contains the sad results of people who didn't wear their AFDBs and, therefore, were sucked into the Peeps vortex.
