While Kathy plan a surprise birthday party for her father, Mr. Frisby tries to teach Ernest the proper way to 'hard sell' a customer, a technique that meets with disaster - so much so that Ernest gets fired from his job. With the help of his friends on Jupiter, Ernest develops a sales approach that appeals to his customers' soft spot and manages to sell merchandise that had sat on Mr. Frisby's shelves for years. Frisby hires him back with a bonus and Ernest promptly spends it on a birthday present for Mr. Frisby.
