Watch Larry David and Bernie Sanders react to the news that they're actually cousins

Larry David debuted his impression of Bernie Sanders during season 41 of "Saturday Night Live" to wide acclaim.

The impression was almost not an impression at all, because the point was that the two are basically the same. It was almost like they're related.

And on the season four premiere of the PBS show "Finding Your Roots," David and Sanders discovered that they actually are. 

Interviewing David and Sanders separately, host Henry Louis Gates, Jr. explained how guests' DNA are compared and matched for similarities. In front of each guest was a book that would reveal his cousin.

"I hope it's a good athlete," David said. When he opened the book and saw a photo of Sanders, he laughed and said, "What the hell?!"
