"Brady Bunch" mom Florence Henderson, who in the past has hawked a popular brand of cooking oil, is now feeling fried over some T-shirts being sold on the Internet by a label with the very un-Brady-like name of Serial Killer. The garments depict Henderson's face and the caption "Porn Queen." A print ad bearing Henderson's picture and signature also endorsed a store selling the shirts: "When I'm not soaked in Wesson Oil from head to toe, I'm shopping at Gravenstones," it declared. Henderson announced this week she is suing both companies for damages.
