<P> The scenes in the opening credits where the trio are frolicking on a boardwalk and riding bumper - cars was shot at the Santa Monica Pier , prior to the building of a larger amusement park adjacent to the pier . A later opening sequence that was shot when Priscilla Barnes joined the show featured the new threesome and the other cast members riding a zoo tram and looking at various animals around the zoo . Those sequences were filmed at the Los Angeles Zoo in Griffith Park . During the opening credits , the little baby boy in overalls who walks up to Janet while feeding the goats at the zoo , is Jason Ritter , John Ritter 's elder son . The exterior shots of the apartment building were filmed at 2912 4th Street in Santa Monica . </P>
