The only thing better than Brian Cox appearing on the tellybox? Brian Cox appearing on the tellybox alongside Conan O'Brien.
Just click play to watch his chat with the American talkshow host - which includes discussions about aliens, teleportation and time travel, and Professor Cox swearing in true British fashion.
It also features him being hilariously flummoxed by a comment about Abraham Lincoln. But, hey - he's a man of science, not American history, right?
