- Inspector Michael 'Mike' O'Hara: What's the matter, Bates? Can't you take 'em?
- Detective Bates: [Trying to act macho] Are you gonna come quietly, Falcon?
- Gay Lawrence: [Putting his finger by his lips and mouthing a 'shhh'] Yeah, I won't even wake you up.
- Max Carlson: [to Rita knowingly] I think you can be relied upon to close our deal with 'The Falcon.'
- Rita Mara: I think so. Then we meet at your apartment.
- Max Carlson: That's right. Come on, Dutch.
- Gay Lawrence: [to Dutch] Oh, your hat.
- [Handing him his hat]
- Max Carlson: Awfully sorry we won't meet again.
- Gay Lawrence: [Drolly] Oh, that's one nice thing about my murder.
- Inspector Michael 'Mike' O'Hara: [to Helen, sarcastically about Gay] I'm beginning to think that the worst thing I could do to that guy is let you catch up with him.
- Gay Lawrence: [When he realizes that the crooks intend to throw him down a trap door into the river] You know, they say the best people are using concrete these days.
- Inspector Michael 'Mike' O'Hara: [Discovering that he has mistaken a phony diamond for a real one] That settles it! I'm gonna change my wife's stone for a washing machine!
- Inspector Michael 'Mike' O'Hara: Wait a minute, Falcon. You can't let me down! You're the only guy who knows the diamond racket inside out.
- Gay Lawrence: Get thee behind me, O'Hara.
- Gay Lawrence: You're going to fix a window?
- Needles, a Henchman: [Ominously] No, I'm gonna fix your wagon.
- Inspector Michael 'Mike' O'Hara: [Understating] Only a little murder wrap is all.
- Helen Reed: Murder?
- Inspector Michael 'Mike' O'Hara: Yes.
- Helen Reed: What makes you think you're a detective? Just because your arches are broken down?
- Jonathan 'Goldy' Locke: I tell yuh, I'm as sober as a judge.
- Policeman: I'll put you before one, and we'll find out.
- Inspector Michael 'Mike' O'Hara: [Seeing Gay and Helen embracing] Awww, touching, ain't it?
- Jonathan 'Goldy' Locke: [Referring to a bet he's lost to Helen] Yeah, touches me for a buck.
- Gay Lawrence: [Leaving with O'Hara] Oh, good-bye, darling.
- Helen Reed: [Taking the dollar from Goldie] Yes, it'll be a down payment on my straight jacket.
- Gay Lawrence: I'm just an innocent bystander.
- Inspector Michael 'Mike' O'Hara: Rather a peculiar place to do your by-standing, isn't it?
- Jonathan 'Goldy' Locke: Don't be a chump, the boss will handle her.
- Helen Reed: That's what I'm afraid of!
