Corrected entry: Ash suddenly has a Charmander, but his original Charmander evolved all the way to Charizard a long time ago, and we never see him get another Charmander. He couldn't have gotten another one, as we see each and every single pokemon that he catches within the show. Even in the Japanese-only episodes, he catches a bunch of Tauros, which Oak mentions when he returns to the lab.
Corrected entry: Misty manages to pull Ash and Pikachu out of the water with a fishing rod. I know there's some suspension of belief required, but that's just a little too unbelievable. She's never known to be particularly strong, so pulling out something weighing roughly 120% of her own body weight so easily, causing them to literally fly through the air, is just crazy.
Corrected entry: When Meowth comments that Victreebel's Sleep Powder works well, James closes his eyes, tilts his head up, and says "Yes, we're a knockout combination." As he says this, his nose inexplicably grows to about ten times its normal length, but goes back to normal after he says the line.
