If the crazy old man next door starts talking about 'strange happenings', for goodness sake don't ignore his ramblings to go off and do freebase or intercourse! (his grim visage will come back to haunt you before your demise if you do, and he wasn't even the one to do it)
How about this? Don't take off your clothes. Period. Getting naked in a horror movie is one of the quickest ways to die... unless you're the main character. And do you
really want to chance it?
Besides... think of how embarrassing it would be for whichever poor bastard happened to find your body.
