Silk Stalkings was a type of detective show on USA in the early 90's and probably late 80's too. anywho, i just remembered one episode where this guy tied a girl down on a bed, and was trailing the corner of his jacket over her stomach. she was bucking and had a wide grin. idk about laughter cuz i had to keep my TV down or else my parents would come in and yell. anyway, the guy eventually stopped and then stabbed her in the solar plexus with an ice pick. the rest of the show revolved around solving the murder.
