It aired on Fox in the United States on January 4, 2015, and is written by Alex Carter and directed by Joe Vaux.
In the episode, Stewie and Brian take Chris back in time so he can perform well in a history exam.
At school, Principal Shepherd tells Peter and Lois that Chris is at a "D−" average and will have to repeat the 9th grade unless he passes his history class finals overseen by Mr. Harpington.
Stopping off in 1803 at one of the locations on Chris' history final, they observe U.S. President Thomas Jefferson trying to convince the U.S. Congress to approve the Louisiana Purchase.
Brian and Stewie then take Chris to Brazil before the invention of the soccer ball, Australia before the invention of the shark-tooth necklace (both similar in that the citizens stand around and do hardly anything) and Italy before the invention of pasta where stereotypical Italians are seen bashing rocks against other rocks and exclaiming stereotypical "vowel sounds"; Stewie calls the Italians ridiculous people, transitioning into a live-action sequence where Tony Sirico, angered at the Italian insult, reprimands Stewie about it.
Arriving in the 1990s, Stewie, Brian, and Chris witness a man dancing to Go West's "King of Wishful Thinking".
During the time travel, Brian takes a detour to kill Ivan Pavlov for his experiments on dogs.
In an interview ahead of the start of the season, Family Guy executive producer Steve Callaghan told Entertainment Weekly “I don’t want to spoil the episode too much, but I can say this: Toward the end of the second act, Chris ends up separating himself from Stewie and Brian, and ends up boarding the Titanic.”[2] The episode received an audience of 5.53 million, making it the third-most watched show on Fox that night after The Simpsons episode "The Man Who Came to Be Dinner" and Brooklyn Nine-Nine.
