The Abrasive Side
SpongeBob orders a product that will help him say "no". But things take a turn for the worse when his new "abrasive side" begins to take over his life.
- An Aesop: It's okay to say no, but dont use it as an insult as it would hurt your friends' feelings.
- Big "NO!": Pearl, having been denied new shoes thanks to SpongeBob being asked to. Also SpongeBob himself at the end when he sees Grandma has the abrasive side.
- Big Ol' Unibrow: SpongeBob's abrasive side has Type I.
- Broken Aesop: The episode's intended aesop is that even though it's okay to say no to people, that's no excuse to be rude to them. However, due to Spongebob only being shown to say no to people through his Abrasive side and coming off as rude to them in the process, he is not portrayed in the right when he does say no to them. And both Mr. Krabs and Sandy were rude to Spongebob at the beginning of the episode but they don't get called out for it.
- Call-Back: SpongeBob's "abrasive side" makes an offhand reference to Mr. Krabs keeping his money in his mattress, as was established in "The Lost Mattress".
- Calling the Old Man Out: The abrasive side tells Krabs that he should be paying his employees overtime if he's going to make them work for longer hours.
- The Cameo: Howard Blandy is one of the fish in line.
- Dumbass Has a Point: When SpongeBob admits the reason he couldn't go to Glove World with Patrick was because he couldn't stop doing favors for other people, Patrick tells him that he needs to stand up for himself and say no... though not without asking SpongeBob to scratch his back.
- Extreme Doormat: SpongeBob, as usual. He buys the abrasive side in an attempt to avert it, but it goes a little too well.
- Eye Scream: A businessman steps on SpongeBob's eyes, leaving footmarks in their place.
- Helping Granny Cross the Street: One of the people asking SpongeBob for favors and causing him to miss the bus is his grandma asking him to help her cross the street.
- Here We Go Again!: In the end, now Grandma has the abrasive side, much to SpongeBob's shock.
- Hypocrite: Sandy tells SpongeBob he shouldn't be rude to people, despite taking advantage of him earlier on.
- Informed Obscenity: Mr. Krabs treats SpongeBob's abrasive side using the word "Overtime" as a particularly foul curse word. Forcing SpongeBob to leave until he cleans up his language.
- Jerkass Ball: SpongeBob, thanks to his abrasive side.
- Jerkass Has a Point: Despite eventually Jumping Off the Slippery Slope, SpongeBob's abrasive side was right to call Sandy and Mr. Krabs out on their treatment of him (the former for asking him to be a test subject without notifying him beforehand, the latter giving him an excessively long shift into the wee hours without paying).
- The Man in the Mirror Talks Back: Happens briefly as Abrasive SB laughs at his normal counterpart.
- Mean Boss: Krabs forces SpongeBob to work for extra hours for the exact same amount of money.
- Missed the Bus: SpongeBob misses the bus by doing favors for people.
- Never My Fault:
- The abrasive side completely tells SpongeBob that he drove everyone away, even though it was really the abrasive side's doing.
- Sandy says SpongeBob shouldn't be mean when standing up for himself, ignoring the fact that she was part of the reason he got the abrasive side in the first place.
- "The Reason You Suck" Speech: SpongeBob's abrasive side delivers one to him following his insult to Patrick:Abrasive SB: Don't you remember? We told that pink freak to beat it! In fact, we've already insulted all of your rotten friends, and no one will hang out with you, 'cause you have no friends left, Mr. LoserBob LonelyPants!
