The Poop that Took a Pee is a fictional book written by Butters Stotch as a sequel to The Tale of Scrotie McBoogerballs in the episode "The Tale of Scrotie McBoogerballs".
Although Cartman, Stan, Kyle and Kenny wrote The Tale of Scrotie McBoogerballs, in an effort to write a truly vulgar book worthy of being banned by parents and schools, the boys were afraid of being punished for their work and instead claimed it had been written by Butters. Despite the fact the book was written as nothing more that vulgarity for the sake of being vulgar, readers seem to over-analyze the book, claiming that it has deeper meaning than the boys intended. The book's disturbing subject matter however still causes the reader to vomit before even getting past the first sentence of the first paragraph of the first chapter.
Due to the popularity of the first book, Butters proceeded to write a sequel to the story, The Poop That Took a Pee. However, as Butters does not have the sort of extensive and vulgar vocabulary as the boys, the vulgarities in his book are limited to repetitive references to 'poop' and 'pee'. Although this story was not as vulgar as the one written by the boys, readers claimed that the book had deep meanings and that Butters had "gone to his roots", causing the book to be another success. At least until the book caused a man to murder the Kardashians (a show Butters himself loved), similar to how The Catcher in the Rye supposedly caused a man to kill John Lennon. The murder of the Kardashians caused the public to turn their back on Butters as he was the book's writer and therefore he shares responsibility, thus ruining his status as an author.
