Aunt Erma"" has imposed a format on the inspired lunacy this time: she is the helpless prey of one self-help craze after another, from ""The Sub-Total Woman"" to ""How to Perform Home Surgery Using Sewing Basket Notions."" Happily and predictably, she discovers she isn't up to the mark -- the open marriage suffers from terminal draft, her son's teacher penetrates her defensive body English -- so she goes back to being herself, with a gentle remonstrance against taking oneself too seriously. There's fun along the way -- son Jaws II devours a roll of film from the refrigerator, Erma juggles obscene phone calls at the Save The Whale Sperm Bank, and a snoring husband provides ""the first GP-rated Aviance Night in the history of cosmetics."" It's a little more gimmicky, but also somewhat more fully developed than standard Bombeck fare: the one-liners are there, tucked neatly inside the familiar suburban scenarios, but tackling her self-development both expands Bombeck's range and reins in her topic wanderlust. Longtime followers will cover the course in short order, while the uninitiated will find lots to chew over.
