Dr. Einstein: You shouldn't have killed him. Just because he know something about us, what happens?
Jonathan Brewster: We come to him for help, and he tries to shake us down. Besides, he said I looked like Boris Karloff!

Elaine Harper: But Mortimer, you're going to love me for my mind, too.
Mortimer Brewster: One thing at a time!

Mortimer Brewster: Look, Aunt Martha, men don't just get into window seats and die!
Abby Brewster: We know, dear. He died first.
Mortimer Brewster: Wait a minute! Stop all this. Now, look, darling, how did he die?
Abby Brewster: Oh, Mortimer, don't be so inquisitive. The gentleman died because he drank some wine with poison in it.
Mortimer Brewster: How did the poison get in the wine?
Martha Brewster: Well, we put it in wine, because it's less noticeable. When it's in tea, it has a distinct odor.
Mortimer Brewster: You mean, you... You put it in the wine!
Abby Brewster: Yes. And I put Mr. Hoskins in the window seat, because Reverend Harper was coming.
Mortimer Brewster: Now, look at me, darling. You mean, you mean you knew what you'd done and you didn't want the Reverend Harper to see the body?
Abby Brewster: Well, not at tea. That wouldn't have been very nice.
Mortimer Brewster: Oh, it's first-degree.
Abby Brewster: Now, Mortimer, you know all about it and just forget about it. I do think that Aunt Martha and I have the right to our own little secrets.

Mortimer Brewster: Look, you can't do things like that! Now, I don't know how I can explain this to you. But, it's not only against the law, its wrong!
Martha Brewster: Oh, piffle!
Mortimer Brewster: It's not a nice thing to do. People wouldn't understand. He wouldn't understand. What I mean is... Well... This is developing into a very bad habit!

Mortimer Brewster: Now look, darling, how did he die?
Abby Brewster: Oh, Mortimer, don't be so inquisitive. The gentleman died because he drank some wine with poison in it.
Mortimer Brewster: Well, how did the poison get in the wine?
Martha Brewster: Well, we put in wine because it's less noticeable. When it's in tea it has a distinct odor.

Mortimer Brewster: What is this? Did everybody in Brooklyn know I was going to get married except me?
Martha Brewster: We knew you'd find out about it in time.

Mortimer Brewster: Yeah, yeah, I know that bromide. Something borrowed, something blue - old, new! Rice and old shoes, carry you over the threshold, Niagara Falls - all the silly tripe I've made fun of for years. Is this what I've come to? I can't go through with it. I won't marry you and that's that!
Elaine Harper: [Adoring] Yes, Mortimer.
Mortimer Brewster: What do you mean, "Yes, Mortimer"? Aren't you insulted? Aren't you going to cry? Aren't you going to make a scene?
Elaine Harper: [Adoring] No, Mortimer.
Mortimer Brewster: And don't "No, Mortimer" me either! Don't... Don't you see, marriage is a superstition, it... It's old-fashioned, it's... I... Ohhhh...
[He kisses her and hauls her into the marriage license office]

Lt. Rooney: What has occurred?

Jonathan Brewster: [pulling on surgical gloves] And now doctor... we go to work!
Dr. Einstein: No, Johnny. I cannot operate without a drink!
Jonathan Brewster: Pull yourself together, doctor!
Dr. Einstein: I cannot pull myself together without a drink!

Jonathan Brewster: [threatening Mortimer] If you tell O'Hara what's in the window seat, I'll tell him what's in the cellar.
Mortimer Brewster: Cellar?
Jonathan Brewster: There's an elderly gentleman down there who seems to be very dead.
