As of yesterday, I officially own a foil tinhat that I made with a friend who thinks they are only to deflect brainwaves and have no other meaning at all (poor naive child >.<) - I tried to make it into a deerstalker and stopped halfway though, and as such am now the proud owner of a tinfoil helmet with one flap sitcking out at 90 degrees on one side. Subtle.
I also find it immensely useful for keeping lollipops on when you need your mouth for talking.
So yes, that's that bit of information out there now, aren't you glad? >__<
