LOW VOLUME -- REMEMBER TO TURN DOWN THE HEADPHONES AFTERWARD!

A Las Vegas woman, who was home alone at the time, found a stranger knocking on her door and asking to speak with her. He repeats the same questions, over over, until the husband -- speaking through the ring system from elsewhere -- asks him, "who are you?"

That's where things get 100% NOPE.

Vegas police later arrested the man on numerous charged but have reportedly been unable to identify him, booking him under 'John Doe' for now. Just in case that brought you down a little, here's a much more hilarious and fun-loving psychopath to enjoy.
