A Battery Ad Built as a Counterpunch
Duracell had already made the toy rabbit a battery mascot: its ads showed drum-playing rabbits that eventually stopped, while the one powered by Duracell kept going. The image turned an invisible product difference—how long a battery lasts—into something viewers could watch.
Energizer answered by borrowing the setup and changing the punch line. In its ad, a line of toy rabbits drums across the screen, but one keeps marching after the others have quit. The pink rabbit in sunglasses was designed to make the rival’s familiar demonstration look like an opening for a joke: even the rabbit ad could be outlasted.
The Joke Was Also the Product Claim
The parody worked because the action did double duty. The rabbit’s relentless drumming was comic, but it also acted out Energizer’s selling point: its battery would keep a device running longer. Rather than explain battery performance in technical terms, the commercial gave viewers a simple test they could understand at a glance—who stops first?
That made the Energizer Bunny more than a one-off gag. It became a recognizable character whose defining trait was persistence, while the original advertising idea remained easy to identify in the background. The rivalry turned a competitor’s mascot into the setup for Energizer’s own, more enduring punch line.
