Crooke: Do you know where Woodridge Avenue is?
Robinson: Yep, back the other way.
Crooke: Do you know how many times I dropped my gun tonight?
Robinson: Yeah, five times so far.
Crooke: Whadda you mean so far?
Robinson: Well, you're not home yet.
Robinson (about Crooke): Okay, I'll bring him in.
Crooke: Be careful. He may have another gun.
Crooke: The Maltese Falcon? Gee, I wish I was home when you called.
Robinson: So do I. Then you'd have an alibi.
Crooke: Where are you calling from?
Robinson: Your apartment.
Crooke: But that's impossible. I don't have a phone in my closet.
Robinson: You also don't have a door in your closet.
Mrs. Polasky (points shotgun at Crooke): Reach, copper! One move and I'll blow your brains out! Higher! I wanna see your fingerprints on the ceiling!
Ellen Corby later played Grandma Walton on The Waltons.
The title refers to the 1955 Alfred Hitchcock movie To Catch a Thief starring Cary Grant and Grace Kelly.
