When a man gleefully terrorizes a stranger; a woman, ON CAMERA, in FRONT of witnesses, shrieking with enough breathless excitement to raise the pitch of his quivering voice half an octave because he wants her "to remember him for the rest of her life", that's not only smoke... that's a 5-alarm blaze. And the fat one is just as bad.
