What are some Pokemon bloopers that you remember the most? I can remember quite a few, but I'll list them by season:

Kanto:
In Primeape Goes Bananas, Ash calls Professor Oak to tell him that he just won his Marsh Badge. Professor Oak comments to Ash that Gary has his Rainbow Badge and that Gary has captured 30 Pokemon. However, in Mystery at the Lighthouse, Professor Oak said that Gary had 45 Pokemon. I hope he meant 30 more Pokemon, because remember Professor Oak was talking about eating Ash and Gary's Krabby?

Orange:
In Pokemon Double Trouble, when Luana brings Ash, Misty and Tracey into the hotel, there are a bunch of Pokemon dancing/exercising. One of those Pokemon is a Sandslash. But if you listen to it, the Pokemon says "Sandshrew!"

Johto Journeys:
In Fighting Flyer with Fire, Ash is telling Falkner about Pidgeot. He said the following: "A Fearow was attacking a bunch of Pidgeot, but Pidgeot and I stopped them."
Actually, the Pokemon weren't Pidgeot, they were Pidgey and Pidgeotto.

Johto League Champions:
In All That Glitters, Ash was talking about how his Pokemon helped him to earn all of his badges. He says that Charizard, Pidgeotto, Pikachu and Scyther helped him win many gym battles. One problem: Ash never had a Scyther! Tracey had a Scyther, but Ash never did. Also, when Ash said Pidgeotto, it showed a picture of a Pidgeot.

Master Quest:
In A Tyrogue Full of Trouble, Ash uses Dexter to tell him about Tyrogue. It says that Tyrogue is the evolved form of Hitmonlee and Hitmonchan. Anybody who knows Pokemon knows that Tyrogue is the PRE-evolution of Hitmonlee, Hitmonchan and Hitmontop.
