Antony Perkins in Pretty Poison (1968)

Dennis Pitt: Boy. What a week. I met you on Monday, fell in love with you on Tuesday, Wednesday I was unfaithful, Thursday we killed a guy together. How about that for a crazy week, Sue Ann? 
Sue Ann Stepanek: "Unfaithful Wednesday?" 
Dennis Pitt: I was just joking, Sue Anne. That was in another country. Forget it. I do, no kidding, love you. I love you.
