Trials and Tribble-ations

Trials and Tribble-ations' is the Star Trek: Deep Space Nine sequel to the Trouble with Tribbles, an episode of the original Star Trek. In this episode, Captain Benjamin Sisko must travel back in time to prevent the Klingons from altering history, and changing the events of "Trouble with Tribbles" so that they end in Kirk's death. In their travels to the past, Jadzia Dax reminisces about her previous host's travels with Kirk, and Dr. Bashir lusts after a woman who, in a joke reminiscent of Futurama, may be his great-grandmother.
