Episode #307 "Lucas Matriculus"

 Griffin is working several jobs and is happy the paychecks are finally coming in. Meanwhile, Jurnee asks Hilton to be her "grandfather" and talk about his life at the school’s Grandparents’ Day. Griffin accompanies Hilton to the school and decides to stick around when he sees Miss Williams, Jurnee’s attractive teacher. The class is less than fascinated by Hilton’s presentation, but when Griffin demonstrates what makes planes fly, he grabs the kids’ attention and makes Hilton proud. When the Lucases praise Griffin, he reminds them that he’s always been good at science and graduated from college with a 3.9 average. Jurnee adds that Griffin really inspired the class, and he agrees to tutor Jurnee and her friend Kevin for an upcoming science test. Jurnee aces the test, but Kevin gets a 68% and holds Griffin responsible. Griffin is upset about his failure - but Miss Williams tells him that Kevin’s test score is the highest he’s ever gotten and that Griffin should really think about being a teacher. Griffin gives Kevin a pep talk, and they continue to work on science together. Miss Williams drops off an application for substitute teaching, but when Griffin realizes that it would mean more schooling, which would in turn mean living in Hilton’s attic for at least another year, he decides it’s not the right professional path for him.
