A battle begins when Hugo, the new interactive whiteboard, corrects Mr. Ratburn in front of the class.
Arthur announces the beginning of a match between Mr. Ratburn and the unknown challenger from Cupertino, California. Francine and Buster are shocked to see the challenger, and Mr. Ratburn nervously gulps at the sight of the challenger. Arthur tells the two to have a good, clean match and to shake hands before beginning.
After the title card, Mr. Haney announces that Mr. Ratburn's class was chosen to test out a new smartboard for two weeks. After Brain helps Mr. Ratburn turn on Hugo, the smartboard, the students ask Hugo several questions. Then, Mr. Ratburn tells the students that he has to read the instruction manual first. Then, Brain offers to help Mr. Ratburn after class, and Mr. Ratburn accepts Brain's offer.
After school that day, Brain spends some time helping Mr. Ratburn, and they manage to go through the enitre manual. Then Brain sees something in the manual that proclaims Hugo is 100% accurate and he questions how nothing can be 100% accurate.
The next day at school, Mr. Ratburn is teaching the class about the early history of Elwood City, including how Elwood City was catapulted into the industrial age by the opening of the first steam-powered sawmill. Hugo says that Mr. Ratburn is incorrect when he mentions that Jacob Katzenellenbogan opened the first steam-powered sawmill in Elwood City, because Hugo believes that Francis Wheaton was the one who built it. The class is shocked that Mr. Ratburn was wrong, but Brain isn't convinced.
Brain has a dream that night how Pseudo Meta Corporation intentionally programmed Hugo to only be 98% accurate instead of 100%, claiming that most people won't care about a little 2%, which makes Hugo sad. Brain then wakes up from his dream.
Over the next few days, Brain does some research at the library about the early history of Elwood City, while Mr. Ratburn keeps trying to prove Hugo wrong at school to no success. While doing research at the library, Brain learns in a Spring 1902 article of the Elwood City Gazette that Jacob Katzenellenbogan was the one who built the first steam-powered sawmill in Elwood City after all.
One morning at school, after Mr. Ratburn fails to prove Hugo wrong with a question about puppetry, Brain comes in with Alfred Katzenellenbogan, the great-nephew of Jacob Katzenellenbogan, proving Hugo wrong with a document that proves that Alfred's great-uncle built the first steam-powered sawmill in Elwood City.
Hugo malfunctions after being told by Mr. Ratburn to admit that he isn't 100% accurate, after which the entire class cheers. Mr. Ratburn then asks Alfred Katzenellenbogan if he would mind telling the class about Elwood City in its earlier days, and Alfred is more than greatful to do so. He starts telling the class about the time he visited his great-uncle's sawmill, finishing the episode.
