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. In Paris during 1920, they meet Ernest Hemingway who is in good spirits until Brian's prattle drives him to suicide (though Brian does manage to get his pen). Brian and Stewie then take Chris to Brazil before the invention of the soccer ball, Australia before the invention of the shark-tooth necklace, and Italy before the invention of pasta where Stewie calls the Italians ridiculous people, causing a live-action sequence where Tony Sirico, angered at the Italian insult, reprimands Stewie about it. Then they visit 1776 during George Washington's crossing of the Delaware River where George Washington is wearing arm floaties. They visit 1944 on D-Day where they witness "Double D-Day" as big-breasted females in bikinis cause the Germans to stop shooting while the Warrant song "Cherry Pie" plays. The boys stop to visit Jane Austen to release their time-travel farts. While there, they find that she is attracted to the farts which help inspire her to write "Pride &amp; Prejudice". 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. After an unseen visit to the British Parliament, Stewie gives money to a young Adolf Hitler (whom he mistakes for a young Charlie Chaplin). When they find Chris has learned nothing from the trip for his history test, Stewie calls Chris a moron. This angers Chris so much that he leaves and boards the RMS "Titanic" with Stewie's return pad, leaving them to board the ship to stop him.
