For nearly a quarter-century, from the 1960s until the 1990s, Worthington ran a series of offbeat television and radio advertisements for his auto dealerships patterned loosely after the pioneering "oddball" advertisements of Earl "Madman" Muntz. They began as a parody of a competitor who appeared in advertisements with a puppy recently adopted from the pound. They were known as the "My Dog Spot" ads because each commercial would introduce "Cal Worthington and his dog Spot!" However, the "dog" was never a dog. In most cases, it was an exotic animal being led around on a leash, such as a tiger or elephant. These commercials began as a parody of a long-running series of commercials produced by salesman Chick Lambert, who worked for multiple Los Angeles-area Ford dealers over many years. These commercials invariably began with "I'm Chick Lambert, Sales Manager here at Ralph Williams Ford, and this is my dog, Storm." Storm was a German Shepherd dog, and was usually lounging on the hood of the first car to be featured in the ad.
