Marty Ingels guest stars as Dan, the owner of Samantha and Darrin's diaper service. Or at least, that is who Dan claims to be. In truth, he is a spy from a rival advertising agency, and he plans to swipe all of Darrin's ideas by planting a "bug" in baby Tabitha's rattle. Featured in the cast are Don Keefer as Kimberly and Alex Gerry as Wright. Written by David Braverman and Bob Marcus, "Dangerous Diaper Dan" first aired on November 3, 1966. ~ Hal Erickson, Rovi
