(CNN) - Now we know why Larry David's imitation of Bernie Sanders was so good: They're related.
On an upcoming episode of the PBS show "Finding Your Roots," David found out that he is genealogically tied to the senator from Vermont.
David mentioned the connection between the two during an interview Wednesday night.
However, David couldn't remember the exact link, saying Sanders is "like a third cousin or something."
The news brought smiles to people's faces on Twitter.

David repeatedly imitated Sanders on "Saturday Night Live" during the presidential campaign.
His show, "Curb Your Enthusiasm," returns to air in October.
