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!
