In their pilot advertising effort, Home Paternity has tapped the Chattanooga-based agency Humanaut to promote a high-quality, affordable DNA testing kit that can be conducted in the privacy of your own home.

The cheeky 3:30 minute long-form ad tackles the most famous paternity case of all time—the Immaculate Conception—and reimagines how the age-old Christmas story would play out on a daytime talk show. Virgin Mary appears on the Maury-esque Who’s Your Daddy? to discuss the dubious details of her child’s paternity. Joseph of Nazareth is there to tell his side of the story, and in an interesting twist, he backs up Mary’s claim of divine conception. “I had a dream in which a very pretty man told me I’m not the father,” Joseph says, referring to the Angel Gabriel. The boisterous audience responds skeptically by chanting, “Chump! Chump! Chump!” Amidst the chaos, the host announces that Home Paternity will determine whether or not God is the baby daddy.
