You can block that invisibility thing. A roll of aluminum foil, a little duct tape and a wire coat hanger.
My tin foil hat has a pigeon feather, jauntily attached. It sweeps away all the hypnotic stuff the strangers from other worlds throw at us. On the other hand, maybe the aliens have already landed at the White House. Sure have seen some funny going ons there in recent years! :)
