It is a good ep, one of my favorite. Worf is midwife to Keiko's baby in Ten-Forward!

There is a long tradition of Data's head working without his body. I reference Nemesis (the film, although they can hardly be considered canon) where they pick up B4, data's predecessor, and he talks to them headless while they drive. I also feel like he may have been talking in Time's Arrow when he was detatched from his body, but the more I think about it he was really only talking when he was attached.
