Quote from Captain Stottlemeyer in Mr. Monk and the Red Herring
Lieutenant Disher: This is, uh, all we found. It was in his back pocket. Adrian Monk: "2:30 Sea of Tranquility." What is that? A club? Captain Stottlemeyer: No, I don't think so. Who'd want to go to a club called the Sea of Tranquility? Besides you.
