Pokemon: Season 3, Episode 15

3 - 15: Fighting Flyer with Fire

As our heroes stare in amazement at the Violet City gym, Jessie and James, in a rather pathetic disguise, make their appearance pretending to be conducting a survey on behalf of the Pokémon Bureau. Although Ash, Misty and Brock have never heard of it, they let Jessie examine Pikachu to see if he meets the official Violet City gym standards. Jessie and James confiscate Pikachu and run off.
