Hey Arnold! (1996)

Longest Monday / Eugene's Pet - S2-E4

Continuity mistake: In "Longest Monday" at one point in the episode, Arnold and Gerald run off of a bus and down an alley. Two fifth graders come chasing after them. In the next scene, you see Arnold and Gerald hiding in the sewer under the 5th graders. Arnold then crawls through a very narrow tube, and Gerald follows. You then see the end of the tube and Gerald come out of the it first, and Arnold climbs out last. It would be impossible for Arnold and Gerald to switch places inside the tube because it was way too narrow.

The Aptitude Test / Oskar Gets a Job - S3-E9

Interviewer: You're kidding, right?
Arnold: No, it's not a joke, he really wants to work.
Interviewer: He's 38 years old, he's never had a job, and you expect me to hire him... as an X-ray technician? [Laughs].

Show generally

Question: Does anybody know what year this show takes place? I've noticed that there are all these present day video games, keyboards, etc. on the show, but all the cars are old fashioned.
