Pieces of the front apartment door were rigged on strings to pull out when the door was shot by the guns.
Ethel: Now Lucy, are you sure you heard right?
Lucy: Cross my heart and hope to--oh!
(Ricky is about to leave to go to the basement with Fred to check the furnace)
Lucy: Ricky! You're not gonna leave me at a time like this! When you come back I might be gone.
Ricky: Well if you go, leave me a note and tell me where I can find my clean socks.
Ricky: (taking the phone from Lucy and hanging it up) Now look, honey. Calm down, will you? Let's talk this thing over. Now wait a minute.
Lucy: A lot of talking you're gonna do with a silver wire wrapped around your neck!
Ricky: Now look, honey. Why would those people wanna give us a rub down?
Lucy: (correcting Ricky) Rub us out!
Lucy: 10 o' clock in the living room and all's well!
Ricky: 10 o' clock in the bedroom and all's well!
Fred: 10 o' clock in the hallway and all's well!
Ethel: (muffled) 10 o' clock in the kitchen and all's well!
Lucy: Kitchen inspector, will you report to the living room?
(Ethel enters with a turkey leg in one hand and her gun in the other)
Ethel: Yes sir.
Lucy: Ethel are you eating on duty?
Ethel: No sir.
Lucy: What's that?
Ethel: Oh uh...well I'm not very good with a gun so I thought if somebody tried to sneak in the back door I'd beat them to death.
Lucy: Ethel, I hope they get here before you eat your club away.
Lucy: It was only a very clever ruse that I managed to escape from their apartment right under their eyes.
Sergent Morton: How did you manage that?
Lucy: I pretended to be a chair.
Sergent Morton: I don't think the police can help you madame. Why don't you call an upholsterer?
Sergent Morton: Thirty-second precinct, Sergent Morton speaking.
Sergent Morton: Name please.
Lucy: They're going to rub us out, and they're not going to use an eraser either.
Lucy: Ethel, you're nuturing two vipers in your brownstone bosom.
Lucy: Listen, just because I promised Ricky I wouldn't set foot in this apartment doesn't mean I can't set knees in.
Mrs. O'Brien: That's pretty corny dialogue.
Mr. O'Brien: Yeah, even for television.
Ethel (to Fred): You're never too busy to do anything when there's a blond around.
Lucy: Ethel Mertz, how do you dare let a woman like that with a figure like that come into this building?!
Ethel: Say, that must be the new tenant coming up now. Isn't he handsome?
Lucy: Handsome? How can you call him handsome with those bugged out eyes and long hairy legs?
Ethel: Huh? Hey, you got a fly on the lens.
Ricky: Come on honey, I want my breakfast.
Lucy: There's some coffee over there. I'll make you some soft boiled chairs in a minute.
Lucy: I mean eggs. Look at those chairs, will you, Ethel?
The original opening sequence had changed in this episode. In this new sequence, the animated Lucy and Desi are in a field plastering a Philip Morris box with the star names and the title.
K.T. Stevens (Mrs. O'Brien) and her husband Hugh Marlowe were among Vivan Vance's closest friends.
Hayden Roarke (Mr. O'Brien) would end up playing Dr. Bellows on I Dream of Jeannie 14 years later.
