The Freshman

Harold Lamb (Harold Lloyd), a bright-eyed but naïve young man, enrolls at Tate University. On the train there, he meets Peggy (Jobyna Ralston). They are attracted to each other.

Harold decides that the best way to ensure his popularity at school is to emulate his movie idol, The College Hero, down to mimicking a little jig he does before greeting anyone, and taking his nickname, "Speedy". However, the College Cad (Brooks Benedict) quickly makes him the butt of an ongoing joke, of which the freshman remains blissfully unaware. Harold thinks he is popular, when in fact he is the laughing stock of the whole school. His only real friend is Peggy, who turns out to be his landlady's daughter, described in one of the film's title cards as "the kind of girl your mother must have been". Read more on Wikipedia.
