Larry David spent a good amount of 2015 and 2016 portraying Bernie Sanders on Saturday Night Live in one of those inspired SNL casting decisions (like Tina Fey as Sarah Palin, Will Ferrell as George W. Bush, or Tom Hanks as the Santa Claus for Halloween). Sanders even returned the favor, unveiling his own Larry David impression during the Democratic primary campaign. Now we know why both of their impressions were so spot-on: the two are actually distant cousins!

That discovery (which we learned earlier this summer) was made during the filming of what was last night's episode of PBS’s Finding Your Roots. Watch below as host Henry Louis Gates Jr. revealed the news to both men, who seemed delighted by it. "People talk to me about Larry David, and I say, 'He does a better Bernie Sanders than I do,'" Sanders says before breaking out into laughter.

Of course, it's not all that crazy when you take into account the fact that all Ashkenazi Jews are at least 30th cousins with each other. You can see another clip of David exploring his family's roots below, in which he discovers his mother had a different name than he thought: "It's so typical of my mother to withhold something like that."

Oh, and one thing that wasn't released in the clips: David also found out during the program that his great-grandfather fought for the Confederacy in the Civil War and owned two children as slaves. "I was shocked. I was completely blown away [by that]," he told USA Today. "Believe me, the last thing I wanted to do was to find all that out on television. It was very un-Larry like. But I’m glad I did it, because it was interesting personally to me to find out all that stuff."
