Three Hundred Big Boys - S5-E11
Continuity mistake: When Bender is being filmed stealing the cigar, we see the "robocop" showing the footage on his screen. In the wide angle you can see he has the siren on top of his head, then in the next shot it's suddenly not there. Then he actually raises it out of his head in the final angle.
Continuity mistake: When Bender is a "female" and is putting stuff in his locker, in one angle you can see a yellow item next to his pink handbag. Then in the wider angle, this item is gray.
Continuity mistake: Right at the end, Bender is smoking a cigar and says something like "Emotions should be hated." In the very next shot when he has stood up, the cigar has vanished from his hand and there isn't anywhere he would have put it down.
Continuity mistake: When Bender and the other obsolete robots are watching a snail crawl across the beach, the snail is shown to be in the center of the screen with the robots standing around. Cut to Bender inserting a CD in his mouth, it then goes back to showing the original angle, but the snail has suddenly disappeared, and not enough time has passed for it to have crawled all the way out of the shot. (00:12:10)
Continuity mistake: The "Cartridge Robot" never takes the "Introduction" tape out of his slot, but in the wider shot it's suddenly vanished.

Other mistake: When Fry says "Hey Bender" 3 times he then picks up the phone and says "Hey Bender" but watch carefully and you'll see he doesn't pick up the phone he just reaches out and suddenly has it.
Continuity mistake: In the first episode of season 6, "Rebirth", near the end after the real Fry comes out of the Rebirth chamber, the robot Leela says that she and the robot Fry are in love she now has the real Leela's mechanical arm device on. But she never had it before or after that shot.
Attack of the Killer App - S6-E3
Other mistake: As the Antarians are stripping Bender, the hinges for his door are shown on the left. However, the hinges should be on the right.
Lrrreconcilable Ndndifferences - S6-E11
Other mistake: When Lrrr is looking at his reflection in the clothing store, the necklace he's wearing is seen as it appears normally, not reversed as a mirror image should be.
Continuity mistake: Season 6, episode 19 "Yo Leela Leela": When Bender discovers Leela's secret writing place, throughout the entire scene the lipstick marks on his head keep changing places, sometimes disappearing and reappearing. Most noticeable is the one on the right side of his head: it disappears when he is shown from that side, then reappears as soon as the angle changes.
Continuity mistake: When everyone is being scanned by the machine that determines who stays on Earth and who gets evacuated, the machine approves Amy, saying that they were in the same sorority and they do a "Sigma Beta" dance.

Continuity mistake: The five arrive at the theater. When Fry says "Search me, no don't. I'm carrying", there is no-one next to Fry on the left for a good foot and a half. In the next shot, Amy has appeared about a half foot next to him. (00:02:25)
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.
