Love's Labors Lost in Space - S1-E4
Continuity mistake: After Zapp Brannigan shows off his 'big book of war', he returns it to a pouch at the side of his chair. Two shots later there is no sign of the pouch or the book. Also, when he gets out of the chair, there are no buttons on the armrests, but when he returns to it later, there are two on each side. (00:07:20)

Continuity mistake: We can see that the door of the cargo area is nearly on the ground. How come Fry can then run out of the same door and then fall out of the door near the top of the ship? (00:17:00)
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.
