Meyer: We're all romantic. Or crazy.
Josie: I don't have any excuses for what I did.
Carella: We see a lot worse.
Carella: (to Josie) No one shoots a hole in a canoe for practice.
Kling: Why don't you find a girl who can type like I did?
Havilland: Type! Mine can't even read.
Josie: (to George) Now that I've had a taste for money I'm starved for it.
Very good episode with William Schallert cast against type as a hitman and Pat Crowley changing her hair color (at least for a while) as his intended victim.The storyline is a bit shallow as the viewer should be able to guess what's going on but the suspense and the acting in this one make up for it.
