Taffy: You're a little too short for me.
Meyer: I could wear stilts.
Havilland: You think she could handle a meat cleaver?
Kling: I don't know but any girl with legs like that can't be all bad.
King: (about Mrs. Andrade) She doesn't look like the axe murderer type to me.
Carella: Who does? If you could tell a murderer by looking we'd be outta business.
Kling: (about Mrs. Livingston) Do you still feel the same way about mothers?
Carella: She's no mother.
Kling: What is she then?
Carella: Do I have to spell it?
Carella: Let's start with the mother
Kling: Why the mother?
Carella: Because I'm sentimental.
A hand in the garbage can, plenty of hot chicks, good suspense, and a particularly nasty and psychotic villain make for a good episode.
