Watch MyFlixer. A group of boys are playing baseball on a playground, and one of them hits the ball over the fence, breaking the window of a house belonging to a professor. He calls in a repairman, who arrives to fix the window and is admitted by the professor's pretty maid. Attracted to her and wanting to see her again, after he fixes the window he sneaks back to the house that night and breaks it again, hoping she'll call to have him come out and fix it. She does, but it doesn't turn out exactly the way he had hoped.
