The nameplate on Chief Clifford's desk reads PETER J. CLIFFORD.
McCloud: (to Flynn) I'm overly interested in these New York detective things, these crimes of purple passion, axe murders and things like that, they-they fascinate me, I love 'em.
McCloud: (to Barney Sweetwater) Yeah, seems like people never are what they ought to be.
McCloud: Excuse me, Miss Dawn?
Jackie Dawn: Yeah. What are you dressed for?
(at Fifi's Live Models)
Charles "Bubba" White: I never met a New York model before.
Jackie Dawn: Yeah, well neither have I.
McCloud: Slept like a log, ate like a hog.
McCloud: If we'd a had this Jack Faraday character down in Taos, New Mexico, we'd a had him a lot longer than two and a half hours. We'd a had him tied s' tight he couldn't fight the flies off.
Chief Clifford: Is that right?
McCloud: That's right, and branded, you betcha.
Ernestine White: (on the New York hotel where her son Bubba has ensconced her) It doesn't even seem American. It's so elegant!
