To learn the language, she spends time with Harolds manipulative, henpecking wife Edna Trevor, who speaks Italian. Unfortunately, in the process, she also learns Ednas overbearing ways. Meanwhile, Charles, who has a policy of not working for married couples, takes a new job with Rawlins, who was jilted by his bride. With Charles replaced by Mrs. Ford, Stanleys bathroom fills with beauty products and lingerie, and Stanley is kept awake by the television, which his wife watches to learn English. To make matters worse, her highcalorie Italian cuisine causes his weight to balloon, and she informs him that her mother will come from Rome to live with them. ........
