30 Graveyard Shift

Squidward and SpongeBob are forced to work 24 hours a day by Mr. Krabs, so that he can get more money. Squidward soon gets bored, and tells SpongeBob a scary story to just scare him. SpongeBob then gets scared, but is told by Squidward that the story is fictional. However, when Squidward and SpongeBob are alone, the events in Squidward's story begin to occur. But not for long as the ghost of a non-fictional character named "The Hash Slinging Slasher" turns out to be someone who wanted to become a fry cook recruit in the Krusty Krab.
