Hey Arnold! mistake picture

Girl Trouble / School Dance - S3-E18

Continuity mistake: Besides the fact that when Helga is sharpening her pencil, the desk arrangement changes, one of the students visible when she looks at Arnold is... Helga. This happens because the shot is taken from the episode "Helga's Love Potion."

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].

Answer: No, he did not. He is seen getting off the bus with a suitcase, so he must have not been home for a few days so there is no way he could have known.
