Continuity mistake: The food cart dissapears once LaBarbara stops playing it. (00:17:20)
Continuity mistake: At the end of the episode, when Bender and the Countess Delaroca are hanging on to the escape pod, the diamond on the diamond bracelet the Countess was hanging onto changes position between shots.
Continuity mistake: In the intro, before the main titles, the Professor informs the crew that he's booked them on the maiden voyage of the Titanic. When Leela says "Looks nice," at the beginning of the "scary" Titanic montage, the right side of her shirt is undamaged. During the middle of the "scary" Titanic montage, it suddenly becomes torn.
Continuity mistake: The spaceship Titanic, when seen from space and at the dock, has a yellow trim around it. However, when Bender and the Countess are parodying the scene from the 1997 film Titanic, the trim is white.
Continuity mistake: During the Titanic's naming ceremony, Zapp stands next to the ship, with the word "Titanic" in shot, just above the grey part of the hull, very low down on the ship. However, during the rest of the episode, the word "Titanic" is located further up, just below the white trim.
Continuity mistake: Zoidberg holds the airlock open with his claw while lying on the floor. As the door lifts up and opens Zoidberg is stood up and first through the door.
Answer: You are thinking about episode 20 of series 2 - "Anthology of Interest I". She technically never kills anyone, but in the episode she ask a "What if machine" (one of the Professor's inventions) what would happen if she was more impulsive. The machine then shows the more impulsive Leela killing off the Professor to get the money from his will and thereafter killing Hermes, Bender, Scruffy, Cubert, Nibler, Amy and Zoidberg to cover it up. Finally she does something really impulsive with Fry.
