Story
Brian is dismissed from a community college writing class taught by Professor O'Callaghan, voiced by Stephen Root, for lacking fresh ideas. Stewie takes him to meet authors through the time machine. Mark Twain comes back with them, discovers pornography on Brian's phone and gives up writing, which puts his books at risk. Brian submits The Adventures of Huckleberry Finn under his own name, leaves its language untouched and is expelled. The pair track Twain down in California, where he is performing in pornography, and persuade him that writing is the rarer gift. He returns to his own time with a stolen sex toy and builds a business on it.
