Mr. Arnold: I'm stage manager here and this opera's going on tonight even if Frankenstein walks in.
Charlie Chan: Small things sometimes tell large story.
Sanatarium Guard: Say, I worked around sanitariums before. It's not so bad. I like the cuckoos myself. They're the same as anybody else, only they're smart enough to admit they're nuts.
Sergeant Kelly: [looking at a note written in Chinese] What's that? A laundry list?
Charlie Chan: Much laundry, but all dirty.
Inspector Regan: Kelly, you stay here. It might do you a little good to meet a real detective.
[after a pause]
Inspector Regan: Ask Mr. Chan to come in.
Sergeant Kelly: Wait a minute! You haven't called Chop Suey in on the case? Have you, Chief?
Inspector Regan: No, but it's not a bad idea, and take your hat off! You could learn a little politeness from the Chinese too!
Charlie Chan: Honorable father once say, "Politeness golden key that open many doors."
Sergeant Kelly: I don't like that guy Borelli! I think he uses perfume!
Charlie Chan: Roses and romance like tenor in opera - sing most persuasive love song.
Mr. Arnold: My name's Arnold. I'm stage manager here, and this opera is going on tonight even if Frankenstein walks in.
Charlie Chan: Man who ride on merry-go-round often enough finally catch brass ring.
Charlie Chan: Very old Chinese wise man once say, "Madness twin bvrother of genius because each live in world created by own ego. One sometimes mistaken for the other."
Charlie Chan: Case still wide open like swinging gate.
Sergeant Kelly: Watta yuh mean?
Charlie Chan: Gravelle not murderer.
Inspector Regan: Not Gravelle?
Charlie Chan: Excuse please, will demonstrate hypothesis.
Sergeant Kelly: What?
Charlie Chan: Word of Greek origin, hypo meaning...
Sergeant Kelly: [interrupting] Hypo! I get it! He's hittin' the pipe again!
Mme. Lucretia Borelli: Is this some ridiculous attempt at saving your face, Mr. Chan?
Charlie Chan: Humble countenance merely facing facts.
Sanitarium Guard 1: What's the mater Joe? Nervous?
Sanitarium Guard 2: Aw this job gives me gooseflesh. You're new here, but in a couple of months you'll get as jumpy as me.
Sanitarium Guard 1: Hey I've worked around sanitariums before, it's not so bad. I like the cuckoos myself. They're the same as anyone else only they're smart enough to admit they're nuts.
Lee Chan: I knew we were on the right track Pop! The first time I saw Madam Borelli, I was sure she was guilty, because...
[the visor on his helmet slams shut, cutting him off]
Charlie Chan: Case now closed.
Mr. Arnold: Did you ever see a baritone you could trust?
