[Andy is on the phone to a mentally unstable caller]

Det. Andy Sipowicz:
So you got your coat hangers hangin' from your windows, right? Did you string four hangers per pane? Radio and ultraviolet waves, yeah, yeah. Any attempt whatsoever to control your mind from beyond your windows, those hangers are going to neutralize. Right. What about the aluminum foil; did you cover your ceiling? Well, then, you're in business. You've got yourself an alien-thought-proof room there, right. Look, one other thing effective with these control rays is, uh, refuse to think about 'em, yeah. Take a walk, read a book. We call that the "delusion technique." You fend them off with what you're thinking, and it gradually weakens their hold. Alright, yeah. Wonderful, yeah... sure thing, keep in touch.
