- Tommy Chan: Hey, you know, Pop, I've got an idea about this case.
- Charlie Chan: Yes? Well?
- Tommy Chan: Well, I had an idea, but it's gone now.
- Charlie Chan: Possibly could not stand solitary confinement.
- Tommy Chan: When it comes to detective work, I know my P's and Q's.
- Charlie Chan: But are you familiar with rest of alphabet?
- Charlie Chan: I remember you since last time I arrest you. Is six years ago in Singapore, remember?
- Cooper: Yeah, I remember.
- Charlie Chan: Very great pleasure to arrest you again, Mr. Cooper.
- Mrs. Marsh: You're stupid thinking these people would murder anyone. They're too busy murdering the English language.
- Capt. Flynn: Say, do you suspect any of the people who were present when she died?
- Charlie Chan: Suspect everyone on general principle.
- Birmingham Brown, Chauffeur: [at the police station] If he ain't a black market man, my name ain't Birmingham - and I can prove it is.
- Tommy Chan: He's right. That man's business is as dark as a...
- [looking for something dark to point at]
- Birmingham Brown, Chauffeur: It ain't exactly THAT dark.
- Birmingham Brown, Chauffeur: Well, if it ain't, uh...
- Ben Carter: Ben Carter's my name.
- Birmingham Brown, Chauffeur: Benjamin Carter! Yeah! Boy, it's been a long time. I haven't seen you since...
- Ben Carter: Longer than that.
- Birmingham Brown, Chauffeur: Yeah?
- Ben Carter: The last time I saw you, you was living over...
- Birmingham Brown, Chauffeur: Oh, I moved from there.
- Ben Carter: Yeah?
- Birmingham Brown, Chauffeur: Sure. I moved over to, uh...
- Ben Carter: How can you live in that neighborhood?
- Birmingham Brown, Chauffeur: I don't know.
- Ben Carter: Now where I'm living, I only pay...
- Birmingham Brown, Chauffeur: It ain't THAT cheep, is it?
- Ben Carter: Sure it is.
- Birmingham Brown, Chauffeur: Hey, looky here.
- Ben Carter: What?
- Birmingham Brown, Chauffeur: Is you still married...
- Ben Carter: No, I divorced her.
- Birmingham Brown, Chauffeur: Yeah?
- Charlie Chan: [after accidently bumping a passer-by] Oh, I beg your pardon.
- Horace Karlos: Sir, to meet a gentleman who apologizes for bumping you in these days is a rare thing, indeed. He is either a coward or a gentleman. I give you credit for the latter.
- [they both bow]
- Birmingham Brown, Chauffeur: As mad as I am with that man, I hate to think of what I think of him. It makes me blush.
