Challenge of the Samurai - S1-E4
Continuity mistake: When Ash goes to get a Poké Ball for the first time, the ball is upside down, but in the next shot, it is upright. Also, behind the same Poké Ball, there is another one, but in the next shot, there is not. (00:03:19)
Answer: There are a lot of fan theories around this, but the most common theme is that Pikachu had another trainer before Prof. Oak, who gave him to Ash. Pikachu didn't appreciate being handed over.
