Plot: Cybill's hot flashes and herbal treatments don't make her feel any younger, nor does Ira's visiting mother Ruth, who has traded in pantsuits for trendy clothes and an herbal pleasure of her own (or, as she calls it, ""a little sweet wheat""). But Ruth is a hit with Zoey, since she arrives in a pink Cadillac that's a present for her granddaughter, much to Cybill and Ira's dismay
