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)
Xmas Story - S2-E8
Continuity mistake: When Fry looks up at the clock tower the display reads "04:26" which implies it is 4 in the morning, instead of before sunset. In addition, once he has climbed up to the top of the tower, the clock has no 0 before the time and simply reads "4:26". The zero returns right at the end of the episode, in a wide shot of New New York. (00:12:40)
Xmas Story - S2-E8
Continuity mistake: While Fry is commenting on it being his first Christmas without his family, it can be seen that the door to the hallway is open. but when Hermes comes in, there's the sound of the door opening. Also, Hermes waves the two stacks of cards. The stack in his right hand has a red envelope in it that changes to white in the wide shot.
Xmas Story - S2-E8
Continuity mistake: When Bender starts serving the bird for everyone, you see a chair between Fry and Tinny Tim. In the closer shot, Bender is in between Fry and Tinny Tim where the chair should be.
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.
