The Puttermans were a family of plastic robots who outlasted others, thanks to their Duracell brand batteries (a playful reference to their deadpan 1970s ad campaign which featured head-to-head competition between toys). The campaign was made to combat the successful Energizer Bunny ad campaign. The fictional Brand X "other battery" depicted in the ad was made to look like rival Energizer batteries, much in the same way that Energizer's fictional rival "Supervolt" was made to resemble Duracell batteries.
