That's because the Seinfeld co-creator and Sanders are actually third cousins.
David came to the realization while filming an upcoming episode of the PBS show, Finding Your Roots, hosted by historian Henry Louis Gates. The show researches the family history of various celebrities.
The revelation came Wednesday when a reporter, who had received an advance copy of the show, asked David about it during an appearance on a panel for the Television Critics Association.
