Plot

After being dismissed from a writing class held by Professor O’Callaghan (Stephen Root) at a community college for his inability to come up with fresh ideas, Brian wishes he could find some inspiration. Stewie introduces him to numerous classic writers via his time machine, including Luke the Evangelist, Charles Dickens, Ernest Hemingway, and Mark Twain. After hitting it off with the latter, Brian insists he follow them back to the present, where they fill him in on the years he missed. While looking up some modern terms on Brian’s phone however, Mark Twain becomes hooked on pornography and renounces writing, which puts classic literature in jeopardy. Figuring that Twain’s stories are more important than Twain himself, Brian tries to sell off The Adventures of Huckleberry Finn as his own without updating the language. Joe and the rest of the students are offended by it and Brian gets expelled from Professor O’Callaghan’s writing class. Chris reveals that Twain’s influence has ruined porn and suspect that he’s in California. Stewie and Brian discover that he’s become a porn actor himself and convince him to go back to his time, knowing that anyone can make porn but not everyone can be a great writer. Twain agrees, but swipes a tug tube on his way home. In the final scene, the Griffin family see a commercial of Twain’s Tug Tube business that Twain had also started and is now run by Mark Twain V. Brian and Stewie are concerned that this might be too big to undo as Chris is heard shouting who took his Tug Tube out of the dishwasher.
