A depressed Plankton diffidently goes to the Krusty Krab one morning without a plan to steal the formula, telling Karen that he will "wing it." When he goes inside, he slips on a wet floor and is ridiculed by Mr. Krabs. Two observing customers comment that there should be a wet floor sign, and that they would sue Krabs if that happened to them. Plankton then pretends to be horribly injured, and threatens to sue unless Mr. Krabs gives him the formula, but Krabs obviously refuses.
Fearing that he will lose the case, Mr. Krabs hires a lawyer named Richard A. Bottomfeeder, who tells him that he won't charge him anything, unless they win, and that they will counter-sue Plankton for everything he owns. Later, in Mr. Krabs' office, SpongeBob wants to read his testimony speech to Mr. Krabs. However, Mr. Krabs tells SpongeBob he could be a liability. As they prepare to leave for the court hearing, Bottomfeeder slips and falls, breaking his back. He gives SpongeBob his briefcase, saying, "The one thing you need to win this case is in this here case." SpongeBob takes Bottomfeeder's suit and arrives late to the hearing, dubbing himself "SpongeBob LawyerPants." When the first witness takes the stand, however, SpongeBob and Mr. Krabs realize that Bottomfeeder didn't give them the combination of the suitcase.
Plankton comes to court in a wheelchair and cast, and gives a convincing testimony, earning the sympathy of the jury. Meanwhile, SpongeBob desperately attempts to open the case, but to no avail. Plankon uses the fact that Krabs does not own a "wet floor" sign as evidence against him, while SpongeBob only demonstrates Krabs' unhealthy greed in his attempts to defend him, accuses Plankton of being a fake, but the courtroom goes against Krabs. He then calls Squidward to the stand, but Squidward testifies against Mr. Krabs, saying that this is his only day off in three years.
Mr. Krabs tells SpongeBob to give up, but SpongeBob gives a short sermon telling him that they can't quit now. When he finishes, he hits the case lightly, and it opens. They peer inside, only to find a Krabby Patty. Realizing that they can win the lawsuit with this, SpongeBob calls Plankton to the stand and seduces him with the Krabby Patty, eventually getting him to confess. Plankton then tries to steal the Krabby Patty, but is quickly stopped. The jury goes into deliberation and finds Mr. Krabs not guilty, but still proclaiming that he is cheap. SpongeBob then gives Mr. Krabs a homemade "wet-floor" sign, riddled with nails and shoddy paint. Mr. Krabs accepts the gift because it is free.
Running Gag: People slipping on the wet floor. Mr. Krabs and SpongeBob struggling to open the case.
When SpongeBob said that Mr. Krabs being cheap was a "ludicrous statement," in many other episodes SpongeBob agrees that Mr. Krabs is cheap for example, in "Krabby Land," SpongeBob said that all he saw was "Cheapy the Cheapskate" (Mr. Krabs), and in "Pickles" and "Can You Spare a Dime?." SpongeBob calls Mr. Krabs a "crustaceous cheapskate" which kind of proves that SpongeBob thinks that Mr. Krabs is cheap.
When Plankton said "That was easy," he sounded extremely similar to the "That Was Easy" button normally sold at the store Staples.
This is the first time something was set to "obliterate," in this episode's case, SpongeBob's blender. The second will be in "License to Milkshake" with Captain Frostymug and his Shake Simulator.
Squidward mentioned, when he was called up to defend, he said that it was his first day off in three years. He could have been referring to the episode "Squid on Strike."
In real life, the jury would have had to deliberate to review the evidence before giving the verdict.
Despite the fact that Plankton was faking his injuries, Mr. Krabs would be liable because there was a potential for injury. Mr. Krabs had a duty of care to keep the floor slip free and/or provide proper signage to designate a slippery floor, and he could be charged with negligence because he did not meet whatever standard of care exists in Bikini Bottom.
When Plankton and Mr. Krabs enter the court room, the music from The People's Court is heard.
When SpongeBob opened the case, the Krabby Patty wasn't hot but when he showed Plankton, it was.
At the end of the episode, the jury deems Krabs not guilty. However, this was a civil trial, meaning Krabs could have been found liable. "(not) Guilty" is only used in criminal court.
When Plankton says, "I'm sorry Gram-gram!" he says it as if she was dead. However, she was still alive in "Gramma's Secret Recipe," but it could've been his other Grandma or he lied.
In most other episodes, there is a wet floor sign at the Krusty Krab.
When Plankton enters the courtroom, the fish on the right on the door is blue. When the jury is seen again, the fish is orange. The third time they are seen, she is blue again.
When Plankton slips and falls, he is next to the counter. But later, he is next to Charlie and Nat's table.
In Bahasa Malaysia version, when the jury cries after hearing Plankton's fake story, their cry sound was mute.
When Mr. Krabs goes after the dollar in the room, Tom's eyeballs are colored white instead of yellow and after SpongeBob yells "Answer the question!" to Mop, Tom's eyeballs are white again.
In the beginning, when SpongeBob says, "Careful Plankton, I just mopped there," "Plankton" isn't in the captions.
Charlie and Nat are seen at the table when Plankton slips on water. However when Mr. Krabs teases Plankton they are both nowhere to be seen. They do return afterwards when Nat gives Plankton an idea.
Before Plankton goes, "Ow, my other arm!," Mr. Krabs had his hand next to Plankton's wheelchair, but then when he says it, Mr. Krabs' hand is right next to Plankton, and then in the next shot, both of his hands are down.
