Hey Arnold!

April Fool's Day - S5-E14

Character mistake: Helga makes Arnold sit in a plate of chocolate pudding as a prank. Arnold then asks Grandpa on the phone to bring him a new pair of pants. When Grandpa arrives, he asks Arnold, "What's that on your pants?" The pudding is not on Arnold's pants; it's on the back of his shirt. (00:06:25)

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.
