In another world, it might seem like inviting a fictional CGI dragon for an interview is just a desperate attempt to make these last episodes of The Colbert Report especially flashy, but we live in this world (EARTH) and Colbert having the dragon from The Hobbit as a guest is actually really great. Smaug is definitely one of the more polite dragons to have appeared on The Colbert Report over the years! It turns out he and Colbert have a lot in common, except Colbert knows more about Tolkien, of course.
