Continuity mistake: When Fry and the kid are racing along the motorway, just after they let go of the cars they are holding onto, they head into a lamp post. This leads them to banging their heads and collapsing on the floor, because the ribbon they were holding onto forces them into the lamp post. When they fall on the floor, the dust shoots up. After the dust disappears, the lamp post has as well, meaning that the ribbon isn't actually tied around anything.

Continuity mistake: As Zoidberg goes to toss his old shell in the dumpster, there is a crack down the back. In a previous shot, we see the back of him for a second and there is no tear in his shell.
Continuity mistake: In the episode "Mars University" we are shown how robots in "Futurama" attend a regular college, alongside humans and other species, over a periode of at least one college semester. Bender even talks about how he attended and majored in bending (minoring in Robo-American history). However, in this episode, we are shown that his entire "education" consisted of downloading a file at the factory where he was made. There is a clear inconsistency in these two stories of Bender's education.

Continuity mistake: When Lucy Lui shines the projector at the evil Lucy Lui you can see the movie running. How is that possible if the projector is not pointed at the screen?
Answer: Yes Leela knew from early on that Fry had feelings for her. They were pretending to be a couple in 'A Flight to Remember' from season 1 and Fry tried to get on dates with Leela ever since. She just didn't show signs of the feelings maybe being mutual before some of the later episodes.
