It looks cooler if you have the sun visor facing backward

For many years, a small coterie of our citizenry has been convinced that tin foil chapeaus will repel the gummint's mind control rays. Four MIT students have put this theory to the test, using a variety of hat designs. They found that the foil beanies actually increase signal strength for radio waves within frequencies allocated for government use.

It requires no stretch of the imagination to conclude that the current helmet craze is likely to have been propagated by the Government, possibly with the involvement of the FCC. We hope this report will encourage the paranoid community to develop improved helmet designs to avoid falling prey to these shortcomings.

Then again, maybe someone paid them to say that.
