Ass Pull: Squidward unashamedly being a fan of Boys Who Cry makes absolutely no sense from just about any perspective and is very hard to swallow. Squidward has been long established to be much more into classical and, for lack of a better term, sophisticated art and music, such as classical style, and him going crazy over a boy band of all things comes completely out of left field. And it's not like he's portrayed as a closeted fan or considers it a Guilty Pleasure either, which would have at least given it some credibility.
Jerkass Woobie: While Pearl is still the Bratty Teenage Daughter she usually is, she's sympathetic in this episode to the mere fact that Mr. Krabs's cheapness won't let him throw her so much as a decent birthday party. While wanting a fancy party may be unreasonable, wanting her dad to think of something other than money for once isn't.
Moment of Awesome: SpongeBob saving Pearl's party by bringing all the gifts he bought with Mr. Krabs' credit card, including the real Boys Who Cry.
"Karate Island"
Broken Base: Some people find this one of the better season four episodes for its humor, other peoples find it one of the worst due to SpongeBob's treatment of Sandy.
Magnificent Bastard: "Master" Udon ostensibly offers to crown SpongeBob "King of Karate" as a ploy to rope him into his real estate scheme. Luring SpongeBob to the fabricated Karate Island, Udon plays to his pride as a martial artist even as Sandy casts doubt upon his words. When she attempts to free SpongeBob from signing Udon's contract, he deploys a series of his minions against her, traps her in a cage and engages her in a karate match himself when she breaks free, before recovering from seeming defeat to scam Squidward as his next mark with the allure of being named "King of Clarinets".
