OMAHA, Neb. -- ABC has inked a deal that may look a lot like 30-minute weekly ads for an insurance company, ShowBuzz.com reported on Monday.

The cavemen featured in Berkshire Hathaway-owned GEICO car insurance commercials have a cult following. Comedian John Lehr told Newsweek magazine that he has been mobbed by paparazzi that want their own photos taken with him in caveman costume. He plays one of his cavemen in the wildly popular ads.

ShowBuzz.com reported that the creators of "Third Rock From the Sun" have signed a two-year deal with ABC to create a sitcom based on the cavemen. Bill Martin and Mike Schiff reportedly signed a seven-figure pact, which has an option for a third year. They also will develop new projects for ABC TV Studio.

Much like in the ads, the three cavemen will navigate regular modern life from their homes in Atlanta, ShowBuzz reported.

The popularity of the cavemen has been good for GEICO. Newsweek reported that since 1998, sales have jumped to $11 billion from $2.8 billion. The insurer's own site offers caveman merchandise for sale.

Can the cavemen make it as TV stars? The site also allows fans to read the cavemen's blog and tour their apartment on CavemansCrib.com.
