Charlie Chan
- Curator: It's very nice of you to give up a quiet evening at home.
- Charlie Chan: Quiet evening?
- [Charlie chuckles]
- Charlie Chan: I don't have to be a detective to know that you don't have ten children.
- Lord Buckley: The diamonds never should have been left unguarded.
- Charlie Chan: Possibly, but advice after a mistake is like medicine after the funeral.
- Stanley Chan: But how can you know where the jewels are, Pop? There were absolutely no clues.
- Charlie Chan: Very true, but sometimes no clues are biggest clue of all.
- Nancy Chan: Wait a minute. Where's Chu-Chu?
- Henry Chan: Oh, no. Not lost again.
- Charlie Chan: You like to be detectives? So think. Where would the dog go?
- [the Chan family hears a loud crash, then find Chu-Chu about to feast on some knocked-over dinosaur bones]
- Stanley Chan: Wham Bam, we're in a jam.
- Charlie Chan: Aiya! It appears our job at the museum isn't over.
