On the one hand, it's pretty funny, especially the pictorial showing you how to make the hat using simple, everyday, household items. On the other hand, it's pretty sad if all it really takes to stop alien mind control is a leather hat lined with some plastic sheeting and duct tape.
You'd think they would have figured out some better methods of mind control by now, especially since, y'know, they've already worked out how to travel across the vastness of space and all that.
But what would I know? Do I look like a space alien from beyond the stars to you, puny human?
