Anthology of Interest I - S2-E20
Continuity mistake: When Zoidberg calls a meeting with the other planet express workers he says the clock stopped at 4:15. In one shot, however, the clock is at a different time.
Continuity mistake: As Gunter is crying in the dorm, the number of bananas change between shots as well as the position of them on the floor. The changes are most notable when Fry approaches Gunter in the room.
Continuity mistake: When it's Nibbler's birthday, in a far away shot of Nibbler in his chair, the three balls on it are pink, but in the close up they are green. (00:04:20)
Continuity mistake: At the beginning of the episode there is tape on the armrest of the couch, but later in the episode there is no tape anywhere on the couch.
Continuity mistake: During the court case, the lady judge has a band-aid on her forehead. It disappears and reappears throughout the scene. (00:06:20)
Continuity mistake: Whilst Fry, Leela and the professor are on the log near the waterfall they are very close to the right side of the river. A few shots after Gunter puts the hat back on his head you can see they and the log are now all the way over to the left side of the river.
Deliberate mistake: In the dorm room, Fry's punch cup appears out of nowhere. [According to the DVD commentary, this was done on purpose.]
Bender Gets Made (a.k.a. Bendfellas) - S2-E17
Continuity mistake: When the cops spot Bender at the Oilade stand, the letters on the stand become much bigger than in previous shots, and the price disappears.
Bender Gets Made (a.k.a. Bendfellas) - S2-E17
Other mistake: The strap for Leela's eye-patch on the right side of Leela's head (from her perspective) goes just over her ear. The left side goes above her ponytail. This would prevent the two ends of the strap from meeting.
Put Your Head on My Shoulder - S2-E10
Continuity mistake: After the accident when Fry looks at his body, there is a tool kit or something similar more or less right in between the body's legs. In a few moments there is a shot from above and the kit is several feet to the right of the body without anyone touching it.
Continuity mistake: After the fight with Destructor when Bender lies flatten to the ground, the wrestling manager appears with nothing in his hands. When it cuts he is suddenly holding a cigar.
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.
Xmas Story - S2-E8
Continuity mistake: When Bender goes off the cliff, we see in the overhead shot that there are no kids on the icy lake, nor are there any tress near the lake. When it cuts there are kids on the ice and trees surrounding it. (00:02:45)
Put Your Head on My Shoulder - S2-E10
Continuity mistake: When the tow truck appears to tow Amy's car back to Earth, the window is completely steamed. The tow truck driver only wipes away a small bit of the steam but in the next scene the window is completely clean.
Continuity mistake: In the clip before Fry knocks Fox off the air, the one person says, "Could you repeat the last part? *pause, cut.*" When we later see it broadcast on Omicron Persi 8, it says, "Could you repeat that last, *cut*."
Continuity mistake: When Leela is feeding Nibbler there are two drawers and two knobs right behind Nibbler. When it cuts their positions and appearance change. (00:00:55)
My Problem With Popplers (a.k.a. The Problem With Popplers) - S2-E18
Continuity mistake: When the hippie tells everyone to join hands, the cord from the microphone change position in the next shot. (00:19:10)
Fry and the Slurm Factory - S2-E4
Continuity mistake: When they arrive at the gates there are two slugs with clothing on the one on the left has lighter skin than the one on the right, but when they show the next shot they have changed places.
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.
