Plot:

While attending a writing class at Quahog Community College, Brian is dismissed due to his inability to come up with gripping story ideas. Willing to help him hone his craft, Stewie uses his Time Machine to let Brian meet a multitude of great writers, including Luke the Evangelist, Charles Dickens, Ernest Hemingway, and Mark Twain. The latter in particular makes an imprint on Brian, who offers to let him join them in the present day despite Stewie's insistence that it's a bad idea. The two give Twain a crash course on all the history he's missed, but while letting him look things up on the internet, he discovers pornography.

Brian becomes frustrated by Twain's new addiction, citing him and literature as a whole for why society is the way it is today. Angered, Twain steals Brian's phone and runs off to look at more porn. Figuring that the writing is more important than the man behind it, Brian attempts to preserve Twain's legacy by publishing The Adventures of Huckleberry Finn under his own name, only to get cancelled and expelled from his writing class. After Chris reveals that Brian's actions have ruined porn, Stewie vows that Twain must be brought back to the past to fix everything. He and Brian find Twain having become a porn actor and convince him to return home, although he manages to bring a fleshlight back with him, starting a successful business empire by selling them in his own time.
