i didn't catch the name of the episode, but it's the one where Nightwing and Catwoman team up, to Batman's chagrin. the 'wing and the Cat look at a list of ships coming in to the docks, in hopes to find a clue to the case they're working on. When they show the screen, look at the other names of ships coming in to the harbor: the S.S. Minnow, The Andre Doria... there are others, but those are the only two i caught.
