 With Michael planning to be away from home for a few weeks due to his work, and Sandy needing to concentrate on a major project for school, the Hogan siblings decide they need to hire a temporary housekeeper. After several applicants fail to meet the test, David makes his recommendation: Melanie, a scatterbrained, beautiful blonde who aspires to be a hairdresser. Melanie, as it turns out, had just been fired as a waitress at the local teen hangout for screwing up yet another order, and David - who witnessed the termination - feels sorry for her. Of course, Melanie doesn t work out, as she is so concentrated on her upcoming career as a hair stylist (and planning to perm Mrs. Poole s hair). Eventually, David and Sandy decide they have no choice but to fire Melanie. But Melanie announces she s resigning to take another job, which makes David just as mad. Sandy later remarks that Melanie - although easily distracted - is not a bad person and just might get it together someday. In fact, she may just be a good hairdresser ... that is, until Mrs. Poole comes in with the hairstyle from hell!
