Father Is a Prince (1940)

Carpet-sweeper manufacturer John Bower has no patience with inefficiency, lawyers, or vacuum cleaners. He's a bit of a skinflint, too. His family thinks he works too hard. He feels inferior for not having gone to college, so now he doesn't want his children going, either. His daughter Connie is afraid to break the news of her engagement to Gary Lee, especially since not only is Gary a lawyer and a college grad, but his father owns a vacuum-cleaner company, too.
