Kotsuban uranai! Ranma wa nihonichi no oyomesan - S1-E14
Continuity mistake: The altar brought in by Tofu's mother is a big one (Ranma comments as such), but it's much smaller when everyone prays to it a few moments later. (00:03:35)
Continuity mistake: Debbie Dobson is looking through a photograph album, the pages she has open have photos of her sister Gemma. The angle changes when Gemma enters the room, just before Debbie turns the page the photos that can now be seen are of Debbie herself. (00:04:45)
