Such as at the start, when Harold stops in front of Mr. Green's meat store because he's hungry. Also, while Harold sits across the street from the meat store, Green asks Arnold if Harold is still out there, and the store's front door handle is on the wrong side of the door. Next shot, as Arnold exits the store, the door opens properly. (00:19:30)

The open green front door is back when Harold exits the store. (00:19:05)

Continuity mistake: Helga Blabs It All: While Helga goes after the tape at Sunset Arms, room numbers repeatedly change/vanish, or doors disappear and reappear. Some examples: Door 3 vanishes when Helga lowers herself via rope the first time. When Arnold unfolds the attic stairway, the closest doors are 7 and 8, but when Arnold and Gerald run down those stairs, door 8 changes to door 1. When Grandpa talks to Mr. Hyunh, door 1 is now door 3. When Grandpa and Ernie enter Hyunh's room, door 7 becomes door 5. When Grandma exits door 4, it then changes to door 2.

Tour de Pond / Teachers Strike - S2-E18
Continuity mistake: The kids' teacher in "Teachers Strike" is Miss Slovak, who was their teacher in the first season, but in the first episode of this season they had a new teacher, Mr. Simmons.
Suggested correction: Other than the few episodes that take place during a specific time of year; these episodes are not meant to be taken in chronological order. Just roughly in the same 4th grade school year.
Suggested correction: I agree with the other correction, but it's also worth noting that in the production order, "Teacher's Strike" was made before "New Teacher" was. They were just aired out of order, just like many of the other episodes.

Arnold's Thanksgiving - S3-E14
