- Funny Moments: LOTS.
- Jessie and James's cheesy Valley Girl disguises, complete with Jessie's Totally Radical dialogue (lampshaded by Ash) and James's cheesy falsetto voice that eventually results in a Drop the Hammer moment on him.
- Ash's excited reaction when the Gentleman asks if anyone else wants to challenge his Raticate.
- James's Imagine Spot when he thinks all the Pokémon they will be stealing will be just for him and Jessie.
- The Magikarp Salesman tricking James into buying a Magikarp, and James's Imagine Spot and excited voice and laugh.
- Ash, Pikachu, Misty and Brock eating extremely fast at the buffet at the beginning of the second act.
- Brock lusting over the Gentleman's beautiful female partner (of course).
- Jessie and Meowth's reactions to James buying the Magikarp, especially Jessie beating up James among learning he used both their salaries to pay for the Magikarp. We even saw blood and a tooth flying from the Hit Flash!
- James's depression after finding out he was tricked.
- Jessie vacuuming up trainers' Pokéballs while saying "Suck them up! Suck them up! Suck them ALL up!"
- The Dirty Coward Captain of the St. Anne who claims the ship is "unsinkable" and that he is "just testing out one of the lifeboats."
- Harsher in Hindsight: The St. Anne's captain leaving the ship first becomes less humorous when one remembers the Costa Concordia disaster, In which the ship's captain left prematurely before proper evacuation.
- Tear Jerker: Ash's flashbacks to all the good times he had with Butterfree and the sadness he shows when he begs the Gentleman to trade him back can really hit hard for viewers who've given away something precious, but regretted it later.
- They Wasted a Perfectly Good Plot: While the episode managed to get its point across about how you shouldn't trade Pokemon without really meaning it, some fans couldn't help but wish that Ash was shown palling around and properly battling with Raticate for a bit before returning it.
- Values Dissonance: Team Rocket's disguise as ganguro teens, a distinctly Japanese trend which Americans have often mistaken for blackface. It's safe to assume that the only reason this wasn't cut was that it would have caused a big enough plot hole to take the follow-up episode down with it. That, or they assumed people would just think they applied some form of spray-on tan.
YMMV / Pokémon S1E15 "Battle Aboard the St. Anne"
