Lisa Kudrow gave Conan O’Brien a little lesson in Irish ancestry this week.
The Friends actress is currently the executive producer of the US version of 'Who Do You Think You Are?’ and was one of the latest guests on O’Brien’s late night chat show.
So, while Kudrow chilled on his famous couch, Conan decided to quiz her on why it was taking so long for the show to get to the roots of O'Brien's ancestry.
“Irish ancestry is really tough,” she explained.
“You all have the same name; everybody is called Patrick”.
We’re not sure what you mean Lisa, we don’t know anybody called Patrick O’Brien … oh wait.
