Remember the scene from "Signs"?

Where Mel Gibson's character walks into his living room to find Joachim Phoenix (his movie brother) and Mel's two movie children sitting on the couch with tin foil hats? Now they don't have to look like such total fashion dweebs!

You'll find these at Eric is Great (kind of says it all, no?). He calls them Tin Foil Hats for the discriminating lunatic!
