This episode has one of my favorite James moments, when Team Rocket get blasted by voltorbs and electrodes, and he paraphrases the song classic "Show me the way to go home, I'm tired and I want to go to bed."

LOL His face especially is priceless.
I also really like Gary in this episode. Although he's not as great as he was in "The Battle of the Badge", it's nice to see him and Ash get along reasonably well after the first half of the season.
I also find it interesting that Jessie, James, and Meowth actually considered quitting for all of three minutes. Personally, I'm glad they're still here. Where would the show be today without Jessie's temper, James's personality, and Meowth's wit?
