Nice Girl? (1941)

Prof. Oliver Wendell Holmes Dana is a small-town high-school principal who also has a research study with rabbits underway at his home. He's a widower with three daughters and a housekeeper/cook. He has been awarded a two-year research grant. A handsome advance man arrives to iron out the grant details, and the three daughters vie for his attention. Jane's attraction leads to scheming, raised eyebrows in the town, and some very funny results.
