SpongeBob's cousin, Stanley, comes to visit. He brought a letter for SpongeBob from his Uncle Sherm. It states that Stanley cannot hold a job because he destroys everything he toches, hoping SpongeBob can deal with Stanley better. This turns out to be true, as Stanley messes up almost every single thing he touches (or in the case of the fridge, empties). This starts to bother SpongeBob. Stanley then gets a job at the Krusty Krab, but whenever he messes things up, SpongeBob willingly blames himself for Stanley's messes so Stanley can keep his job. But SpongeBob eventually can't take this any more, and SpongeBob tells Mr. Krabs about how he was constantly counterframing Stanley for his mishaps. But Mr. Krabs has an idea, and he tells Stanley to get a job at the Chum Bucket, with the purpose of destroying the Chum Bucket, and taking advantage of Stanley's troubles. Plankton hires Stanley, thinking that his fry cook skills would be as good as SpongeBob's, as Stanley is related to him by blood. But Stanley accidentally destroys the Chum Bucket, much to Krabs' delight.
