The title is introduced in a staggered fashion. As patrons drive up to a restaurant's valet station, the word "Lions" appears when an elderly couple in a Rolls Royce drive up; then "Tigers" when a couple drive up in a Ferrari 308; then "Monkeys" when a wild costumed couple arrive in a modified Duesenberg convertible; and finally, "Dogs" when Rockford and his date appear in his gold Pontiac.
