Story : Syd firmly tries to fend off the romantic advances of a handsome businessman (guest star David Lee Smith) whose family is linked to the Mob, and lavish gifts begin to wear her down while at the clinic. She diagnoses a sickly landscaper (guest star Tim Ransom) who she suspects is being poisoned by pesticides. Elsewhere among the Hansen clan: Joanie -- on the eve of her new shop opening -- becomes concerned when boyfriend/business partner shows little interest in her infant daughter; Jim indulges himself when he commits to helping Lilly rig up a Rube Goldberg contraption as part of a school project; and Robbie begins to appreciate the hidden allure of Jim's clumsy veterinary assistant in a whole new way.
