Natalie: Professor? Professor Tilburn? Professor Tilburn. Mr. Franklin here doesn't think that Julie's fish you know the one that I showed you, could live longer than a year or two. What do you think?
Adrian Monk: I think it can.
Mr. Franklin: I don't see how. It's a common variety marble fish. Has a miniscule genome size and almost no immune system.
Adrian Monk: Let's go. Let's get outta here. [off Natalie's look] That's true. That's true about most marble fish. But this is a completely different species. This is the North Korean marble fish.
Mr. Franklin: North Korean?
Adrian Monk: It's a very strong fish. It's a very tough fish. Would have to be to live in a country like, uh...
Adrian & Natalie: North Korea.
Natalie: Right.
Adrian Monk: This fish could live for... Oh, my God, three or four years. [Natalie shakes her head] Four and a half or five. [still shaking] Or six. [nods] Or six, six, that's it. Six years.
