The best way to get yourself hundred percent proved protection from brain slugs and alien brain-control transmissions you can wear a tin-foil hat. That's a well known fact. But in order to get two hundred percent protection you need to move further and take some more serious approach for your brain security.
This guy decided that more tin foil the better. He couldn't probably convince his wife in the necessity of the protection layer everywhere so he grabbed his couch, his desktop pc and a few giant rolls of tin foil and moved to his garage, where before they stored some food supplies - you still can see that passage down the floor.
Now he can feel himself relaxed. Or maybe there is a need to put a tin-foil hat too? Just in case..
