Endora casts a spell which enables her son-in-law, Darrin, to speak Italian -- and only Italian. This proves to be an advantage in winning over Darrin's new clients, Chef Romani (Fred Roberto) and Romani's business rep, Signor Acarius (Renzo Cesana, TV's former "Continental"). But things take a sour turn when Romani becomes convinced that Darrin is merely mocking his Italian heritage. Written by Michael Morris, "Business, Italian Style" first aired on September 21, 1967. ~ Hal Erickson, Rovi
